Fiber Reinforced Composites (FRC) are materials greatly used in different sectors (automotive, aeronautics, construction, sport, energy, etc.) due to the increased performances in terms of mechanical properties and lower weight compared to traditional materials, as well as chemical and thermal resistance. However, identified limitation in the FRC market is the necessity of high performance resins at competitive prices, specifically for Resin Transfer Moulding (RTM) and infusion processes. FRC are composed of fibres and a resin to provide consistency. Nevertheless, as a result of the fatigue during its intensive use, these materials might undergo crack formation, which propagation throughout the resin produces delamination, thereby limiting their useful lifetime and producing structural problems.
On the other hand, the outstanding properties of graphene make this material a very useful product for many applications, in particular is a very versatile material that can be used as a structural part of a composite material providing stiffness, mechanical strength, flexibility, thermal and electrical conductivity, etc. APPLYNANO expertise is addressed to the incorporation of graphene derivatives into the composite matrix. Conventional techniques for incorporation of nanoparticles in FRC increase processing time and heterogeneity of final product. Therefore, this would limit the use of graphene derivatives to preimpregnated composites (prepegs), which high costs may hamper its use in sensitive price sectors. The market currently demands products with increased mechanical resistance and toughness at competitive prices. To answer this necessity of the market, APPLYNANO has developed thermosetting resins incorporating graphene derivatives, in particular graphene oxide (GO), optimized for RTM and infusion processing. Our technology is based on a scalable, environmentally friendly and low-cost process whereby a stable dispersion can be obtained through the use of physicochemical techniques with graphene derivatives produced in-house, increasing compatibility between nanomaterial and matrix and allowing us to accurately control the properties of the final product.
