摘要： A reinforcing composite comprising a plurality of layers of reinforcing composite material forming a stack wherein at least one layer of the stack comprises a moulding compound (114) comprising consolidated resin impregnated fiber elements, wherein the resin impregnated fiber elements are obtained from off-cuts or scrap material (112) derived from cutting single layers of reinforcing composite material and/or stacks comprising multiple layers of reinforcing composite material (110).

摘要： Treating an uncured resin matrix composition to impart energy to the resin matrix composition enables a stable Tg to be achieved whereby the resin matrix composition may be stored and has a low tack enabling subsequent processing and handling. The invention provides a method of achieving a stable Tg without the resin matrix composition starting to cure and a method of determining the treatment regime by which a resin matrix composition with a stable Tg may be obtained. The resin matrix composition may be fresh or reused uncured resin matrix composition and may contain fibrous reinforcement.
