Composite materials and method of manufacturing the same

摘要

A fibre reinforced composite comprising a fibre reinforcement layer having a first matrix located from a first surface of the fibre reinforcement to a depth only partially through the fibre reinforcement; and a thermoset resin matrix located from a second surface of the fibre reinforcement only partially through the fibre reinforcement and a corresponding method are disclosed. The first matrix material may be a thermoplastic or a thermoset. The first and second matrices may be the same. The fibre reinforcement layer may be fully wetted. Also disclosed is a method of manufacturing a fibre reinforced composite whereby the fibre reinforcement layer and first matrix are enclosed in an envelope; and a second matrix material is injected into the envelope, the second matrix material being a thermoset resin matrix, whereby the second matrix infuses into the second surface of the fibre reinforcement layer.
