The Influence of the Hot Processing Conditions on the Impregnating Degree of GF/PET Friction Spun Core Yarn

摘要

The way of the friction spun core yarn as the fabric preform used in thermoplastic matrix composites is considered outstanding. The hot processing conditions of forming composites such as the molding temperature, the holding time and the pressure influence the impregnating degree of the composites, which is investigated though the observation of cross-section and tensile strength.
