Chopped Polyethylene Fibre Reinforced Ethylene-Butene Copolymers

This study verifies the option to process chopped polyethylene fibre reinforced polyolefins without causing fibre relaxation. It generates a new family of materials whose property range is as wide as the number of combinations of matrix choice and fibre content. The generic effect of the fibre on the mechanical properties is to turn a soft polyolefin matrix, characterised by low modulus and yield stress and high ductility, into a rigid, high strength composite material.
