Solutions of plastic reinforced with fiberglass for work with sodium hypochlorite

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.

A fire-retardant future: intumescent Composites

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.

Composite materials, a sustainable choice

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.

The recycling of composites. A challenge of required resolution in the very near future

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.

New perspectives in the recycling of the composites

Simulation of the process of curing as a key technology for addressing problems of manufacture of composite materials

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).

New applications of biocomposites in construction and transport sectors

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.

New applications of composites in architecture

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.

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.
