Sectors to the Antipodes by composites

Michael Jaeger

Technical Service - Ashland

In his speech, Michael Jaeger spoke of the sodium hypochlorite, which is used and occurs in many processes, such as the treatment of water and disinfection, odor control, chemical synthesis and the cleaners of exhaust. The liquid containing sodium hypochlorite are corrosive to many materials. Plastics reinforced with fiberglass (FRP) are the preferred building materials, as confirmed in a recent survey of the industry, and as demonstrated in numerous Case Histories published. Jaeger reviewed the main applications of hypochlorite, new and historical studies of chemical resistance, and proposed solutions for a better life of service.

Oscar Gadea Ugarte

Cray Valley Iberica, S.A.

In a society increasingly concerned about the health and safety of persons, ensuring fire safety already is not an option, but an obligation. This was one of the starting points of the presentation of Oscar Gadea, which had an impact on that composites have provided fire-retardant properties in many venues throughout history. However, according to Rossi, as protection against fire regulations are moving, these materials will become obsolete and it is essential to develop new technologies to provide solutions in this regard, both product and process. Cray Valley has launched a new range of intumescent products for composites (FireBlock), for the incendiary safety in fields as diverse as transport, construction and industry.

Eric Dallies

OCV Reinforcements

Eric Dallies talked about innovation in the glass fibre reinforcement and compounds technology carried out by the Owens Corning company. The firm has developed a new generation of technology of reinforcement that redefines the availability and the value of the materials of high-performance glass fibre as a family based on a formula R-vidrio and now has expanded to include glass S high-performance reinforcements. The points of reference for high-strength glass fiber reinforcements are: ShieldStrand reinforcements for the defence; XStrand reinforcements for the sports industry and recreation; WindStrand reinforcements for wind energy; and FliteStrand reinforcements for the aerospace sector.

José María Rodríguez Ramírez

DSM Composite Resins / Euroresins

According to José María Rodríguez, in many respects, the composites are best building materials than the traditional materials, such as metal and cement. The initial benefits include less weight and excellent corrosion resistance. Rodriguez used these and other arguments to defend in his paper the composites as a sustainable choice. Explained that a lower maintenance and repairs result in lower costs and more lightweight materials to facilitate its handling during Assembly by reducing the costs of installation and transport. Composites also offers design freedom allowing the creation of complex shapes. Recent studies in terms of ACL reveal additional benefits with respect to traditional materials. In his lecture showed how DSM Composite Resins is committed to innovation for a healthy future.

According to Miquel Peraire, with the new generation Envirez can be manufactured resins UPR where some of their raw materials have been replaced with others that comes from renewable sources.

Eric Debondue

3B The Fiberglass Company

Sustainability has become, according to Eric Bondue, the main challenge in the chain of value with the technical, political, social and economic dimensions. The green production, optimum efficiency in the use of energy, the reduction of the consumption of fossil fuels are not exhaustive examples of what sustainability means. Bondue spoke of the contribution 3B in this challenge with the development of greener products, better performance and more materials of life. An example is high-performance fiber HiPer-tex.

Hervé Cavalie

Sartomer Europe

During his speech, Hervé Cavalie spoke of styrene as the monomer reagent used to dilute polyesters resins or curing by peroxide vinilésteres. He exhibited the labeling, emissions, the need for attention on the toxicity and the smell of chemicals, as well as cured materials and of the need to find alternatives to styrene. Cavalie spoke of the possibilities of replacing the partial styrene or wholly by Methacrylates signature Sartomer, and gave data on evaporation, reduction of viscosity, the reactivity and the mechanical properties of the cured materials.

Mariano Sastre

Eurofiber - Danobat Group

Mariano Sastre put on the table the recycling of composites out of use, the volume of which has so far been small enough to have its storage or destruction, through different channels, has not constituted a real problem. With the advent of wind energy, in which all blades are constructed with composites, and the fulfilment of their life cycle, the volume of composite materials, which we shall be obliged to "unsubscribe", will be virtually impossible to storagewith which we will be forced to seek solutions to these volumes of material discarded. Sastre spoke of the possibility of recycling as, possibly, the best solution, because if the use of these materials is increasing, will get the recovered to manufacture other composites, albeit not of the same technical category. The paper sought to generate awareness on this issue, and on the need for a financial system, with a recovery rate, allowing the conversion of the waste, and the profitability of the process.

John j. Manso García

Cenim / 2000 Enreco / Acumener research and development

The Rapporteur presented a treatment that allows recycle technically and economically the composites. Obtained by-products, energy and reinforcement fibers, make a sustainable and profitable procedure system economically.

David Hernández Rodero

Sener, Ingeniería y Sistemas, S.A.

David Hernández Rodero explained the growing complexity of the designs with composite materials which makes that the companies manufacturers facing increasingly demanding and hardly predictable challenges related to specific problems of the curing process. An example is the sudden overheating by the exotermia of the reaction, distortions of the piece once released from the mold's manufacture (known as springback phenomenon), or a high spread of results about the planned design. In this context, the simulation of the process of curing techniques of finite element analysis (FEA) was presented as an alternative to the usually slow and expensive process of iteration with prototypes of supplies and cycles of manufacturing, allowing the prediction of parameters of vital importance such as the quality of the curing or the magnitude of the springback which will suffer the piece. The combination of these techniques with analysis of uncertainty and optimization tools can determine the optimal way of controlling certain especially influential factors in the outcome of the process, useful aspect to select designs and production processes with lower dispersion (robust design)(, lesser index of disposable pieces or retrabajables).

Mariano Sastre

Eurofiber - Danobat Group

In his speech, Mariano Sastre described the systems used in the manufacture of large prismatic parts in composite materials: System F.L. Filament - Layiing; the system A.F.L-D.A.F. Automated fabric laying-automatic deposition of fabrics; and the circumferential tied A.T. Sistema.

Senén peace Abuín

Gairesa

The importance of the raw materials and the relationship between the microstructure and the properties of these materials were discussed in this paper, where Senén peace Abuín spoke of the "undisputed" importance of adhesives in some of the most important industrial areas and design formulations depending on the type of applications, with important differences in the selection of the components for each one of them. According to peace Abuín "the best adhesive is not that adheres more", but which has a better performance in the long term.

Antoni Solà Lorente

Applus - LGAI

The Rapporteur offered a view of the current state of technology in manufacturability of structural elements in the aeronautical sector. Had an impact on the projects of innovation in the manufacture of components of high cadence that this involved Spain. Another aspect of the Conference was of Applus-LGAI participation in the development of innovative processes in the field of forming by means of "rolltrusion" of joist type components and in the manufacture of fittings with woven preforms in 3D via RTM (Resin Transfer Moulding).

GIS Daniele Rigamonti

General Manager Brandolph srl

The Rapporteur presented the "PEP" of Brandolph, a package of evaluation of preforms, new concept to address the market. GIS Daniele spoke of preform for glass and carbon fiber made by thermoforming of structural parts of RTM and cosmetics.

Santiago Neira

Gaiker – IK4 technological centre

Santiago Neira spoke of the technology of processing of sheet, one of the more important that allows to adapt the material to the demands of the process and the mechanical demands of the piece to make. It is a method of transformation in which shapes a sheet of composite containing an agent of multiple formats, along with Rosin systems strengthening. The blade is cured and transformed into final product through molding operations by "compression or empty" "hot". During the presentation explained the research developed by Gaiker, which has allowed to develop sheet that combine the properties of the resin vinylester and the epoxy: vinylester to provide the system property of mature and cure in short courses of temperature and epoxy for their excellent mechanical properties.

Ian Lancey

Scott Bader

Ian Lancey referred to the structural adhesives based on metilmetacrilato (MMA) which are specifically designed for joining metals and plastics with little or no surface preparation. This generation of MMA adhesives are used in automotive transportation (buses, trucks and railway), vehicles, marine, agricultural and construction industries, and carries a cost savings and improvements in the performance of the production due to its unique chemistry and properties associated.

Enrique Díaz Escriché

AIMPLAS technological Institute of plastics

During his speech, Enrique Díaz Escriché showed different results of research carried out in Aimplas for the development of new applications of biocomposites in construction and transport sectors. During the presentation was clear concern for the environmental impact of production processes in the industrial fabric of developed countries and its increase in recent years. In this sense, minimizing the impact through the manufacture of products with low energy consumption and raw materials from renewable sources is a viable option in the field of composite materials. The development and validation of new applications based on clean technologies is an opportunity for increased market share of the companies in the sector, technologies similar to the processes of manufacture of traditional composites that can be applied to obtain new lines of more sustainable products. As an example, there are various initiatives of manufacturers for the development of resins from plant oils or reinforcements made from natural fibers. However, improvement in various aspects of such raw materials and their production processes such as the improvement of properties and mutual compatibility is still required.

Andrea Marchesini

RAMPF-Tooling / group Gazechim

The Rapporteur commented on the different techniques for constructing moulds and models based on different materials: machinable plates in PU and epoxy; Paste Epoxy (Close Contour Paste); oversized colada (Close Contour Casting); PU and Epoxí resins.

Juan a. Rovira Soler

Polytechnic University of Valencia

Study of rounds of fiberglass as internal armor for elements of reinforced concrete has been developed over the past few years, however at no time is considered that this armor can work to compression. Juan a. Rovira Soler presented a paper on the development of the research to get a round fiberglass valid to work as domestic armor of elements of reinforced concrete, both traction and compressionas well as his good behaviour with loads of fire in the concrete structure.

Eduardo Galofré Pujol

CEO MEL Composites. Technical Director

During his lecture, Eduardo Galofré Pujol addressed participation of MEL Composites projects on new applications in architecture, providing technical guidance, materials and solutions. Composite materials have been used for decades by markets as the marine, where the structural demands are highest and temperature and humidity conditions are extreme. They have demonstrated that they can be used very demanding projects, like a boat in the America's Cup; or remain unchanged for decades, as evidenced by boats that were built more than 50 years. For this reason, civil architecture is beginning to consider them as viable alternatives to unique projects, and more and more they are earning a place in the studies of architecture.

Javier Jordán García

Pedelta

The presentation summarized the main points concerning design, structural behaviour and construction of two footbridges recently inaugurated in Oñati and Zumaia. Both structures were designed to optimally meet the structural, constructive and functional requirements through the combined use of GFRP and steel elements.

Javier Heredia Alvaro

System Pool

Krion is a Solid Surface by the Porcelanosa group that brings new features to this family of materials, and allows for new possibilities of application. The rapporteur spoke of the emergence of this new generation of materials in the world architecture, which has inspired projects and unpublished applications so far, and that they stand out for their aesthetic beauty, technical approvals and originality. According to Javier Heredia Navarro, the use of these new materials through an exercise in understanding by the architect.

Henry Marquez

Dragados

The paper had an impact in the characteristics that affect the use of composite materials in the construction industry, primarily those that affect the design and development of pieces with an important architectural component. Analyzed the impact on project and engineering costs, and deadlines for implementation, based on the experience of dredging. The company gave as an example the construction of the facades to the Jean Nouvel Auditorium, in the works of extension of the Centre of art Reina Sofia in Madrid. These works were executed between the years 2001 and 2003 and, for the first time in Spain, the use of CAD-CAM techniques for the implementation of a facade of polyester, composed of more than 1,600 sandwich panels was accurate.

Angel Arteaga

The construction Sciences Institute Eduardo Torroja - CSIC

The starting point of the Conference was the fact that, at present is important the sustainability of buildings and the increase of its useful life, which implies the reinforcement of its structures. The strengthening technique is ancient, but within it, the new system of the reinforcement bars, laminates or fabrics for composite materials formed by an array of polymer and resistant fibers of different types (FRP, for its acronym in English) is of great interest and importance is increasing for its properties: lightness, light weight, ease of implementation or durability. During the talk were presented the possibilities and manner of calculation and execution of the strengthening of structures of concrete beams, both bending and shear, and pillars. It also indicated possible drawbacks or limitations with this type of reinforcement.
