| Abstract Scope |
Three-dimensional woven composites have shown great potential thanks to the through-the-thickness fiber reinforcement and exhibit higher damage tolerance, higher inter-laminar performance and elevated impact resistance. Considering the urgent need to reduce CO2 emission, a huge growing demand pushes to replace existing synthetic fibers and matrix by more sustainable bio-based or natural fibers for reinforcement of composite material. Among all the existing natural fibers, flax and sisal fibers appear to be one of the most promising material to be used. However, due to the inherent heterogeneity of natural fibers which are mainly dependent of many parameters; some mechanical performances of the resulted composite materials based on fabrics using these raw materials can have an impact on their lifetime in duty. Thus, designers and engineers feel less confident to use these bio-sourced materials in comparison to other oil dependent materials, which are better known from experimental and modelling points of view. In this study, different fabric architectures have been designed and manufactured based on sisal and flax fibers to evaluate the residual mechanical performance of these 2D and 3D woven structures despite the heterogeneity of their yarns’ linear density. Thanks to these preliminary results on their ability during the weaving process, several 2D woven fabrics have been impregnated with thermoset resin to check the final mechanical behaviors of their resulted composite materials. Besides, it has been revealed the influence of product and process parameters of the 3D warp interlock fabric on mechanical properties of the resulted composite material. |
