Abstract
A polymer composite multiend roving material used to make structural composite parts includes a bundle of fibers held together by a high integrity sizing composition and surrounded by a powder coating polymer material. The powder coating material is approximately 10-80% of the dry weight of the multiend composite roving weight. The multiend composite roving material may then be easily processed further to form a molded composite part having good mechanical properties and high fiber content.
