Influence of the textile parameters on the complex shape forming properties of flax based fabrics

Abstract

This study examines the ability to develop composite parts with complex geometries without defect. An experimental approach is used to identify and quantify the defects such as buckling caused by the bending of rovings during forming. Solutions are developed to obtain a complex shape such as a tetrahedron without any defect by using specially designed flax based reinforcement architecture. However, this solution may not be sufficient for other types of shapes and that is why the optimisation of the process parameters to prevent occurrence of buckles from commercial fabrics was also investigated.
