A novel approach for natural fiber reinforcement manufacturing inspired by a paper-making process is described. The experimental studies focussed on the characterization of composite samples obtained by impregnation of three different types of reinforcement: nonwoven, unidirectional and hybrid. The latter uses short flax fibers as a binder for long fibers, replacing weaving and stitching used in textile-based reinforcements. Benefits of the new manufacturing procedure, in terms of final composites improved mechanical behavior, are discussed. In particular, results show a significant positive effect of the short fiber binder on the transverse tensile and flexural properties. Acoustic emission is further used to study the tested samples damage evolution. The short fiber binder has shown a significant effect on the damage behavior of the hybrid composite. The contribution of the different damage modes (matrix crack, fiber pull-out, fiber breakage, etc.) and the composite failure pattern was strongly influenced by the short fiber binder. In particular a significant decrease of the matrix crack propagation and a flatter rupture surface have been observed. Recent Publications: 1. Mahi H. H., Habibi.
