摘要

A laminar pre-preg of fibre-reinforced curable composite material. The pre-preg includes at least one layer of reinforcing fibres impregnated with a curable resin containing one or more curable thermosetting resin(s) and at least one liquid curative, wherein the curable resin exhibits a cure conversion of at least 95% when cured at a cure temperature in the range of from about 100°C to about 160°C and the cure cycle has a duration of no more than 10 minutes, and the glass transition temperature (Tg) of the curable resin when cured is in the range of from about 130°C to about 165°C.
