METHOD OF MAKING A COMPOSITE PREFORM

摘要

A method to form a part can comprise forming a pattern with a commingled yarn (10), wherein the commingled yarn comprises thermoplastic resin filaments (40) formed from a thermoplastic material and reinforcing filaments (20) formed from a reinforcing material, and wherein the reinforcing material has a glass transition temperature and/or a decomposition temperature that is higher than a glass transition temperature of the thermoplastic material; attaching the pattern to a carrier material (76) to form a preform (70); and using the preform to form a part.
