During extrusion and injection moulding of composites, natural fibres suffer of entan-glement phenomena in the polymeric matrix. Consequently the fibre waviness decreases the mechanical properties of the composites. The most widely used models for the estimation of the IFSS do not consider this phenomenon. This work introduces a method for IFSS calcula-tion taking into account the waviness factor which affects the weight distribution of the fibre length.

Abstract
During extrusion and injection moulding of composites, natural fibres suffer of entan-glement phenomena in the polymeric matrix. Consequently the fibre waviness decreases the mechanical properties of the composites. The most widely used models for the estimation of the IFSS do not consider this phenomenon. This work introduces a method for IFSS calcula-tion taking into account the waviness factor which affects the weight distribution of the fibre length.File in questo prodotto:
