FIBER REINFORCED SYNTHETIC RESIN MOLDED SHAPE AND MANUFACTURE THEREOF

摘要

A process for moulding articles of fibre reinforced plastics material which includes heating and moulding a sheet of consolidated thermoplastics material which has dispersed therein from 20% to 70% by weight of reinforcing fibres which have a high modulus of elasticity (as herein defined) and between about 7 and about 50 millimeters long so that the stresses embodied in the glass fibres cause the matrix to expand into the configuration of the mould and become porous.
