Abstract

One of the main problems of composite recyclability, is to find applications with a positive business case and technically viable. In order to determine possibilities, it is necessary, first, to analyze mechanical properties of materials as well as today available manufacturing processes with this type of products.

Abstract

PLATFORM appear for the need to improve non-intrinsic properties of composite materials, principally its mechanical and electrical properties. The main objective of the project is to analyze the possibility of introducing three new materials in development into the current manufacturing processes, improving the properties of the raw material, more concrectly prepreg unidirectional carbon fibre with epoxy resin. Several material developments are made with carbon nanotubes in three different formats: buckypapers, thermoplastic doped veils and CTN treated prepreg. The implementation of each materials has been studied in current infusion processes, more concretely manufacturing with prepregs and cure in an autoclave. The studied possibilities are: buckypapers incorporated and doped veils embedded in prepreg laminates or full manufacturing with treated prepreg. The obtained results at the 2nd year of the project are satisfactory, but it´s necessary to optimize the materials to automate the manufacturing and improve the final properties.
