CONTINUOUS LONG FIBER-REINFORCED THERMOPLASTIC COMPOSITE BOARD, AND PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2022/252661

A1

A continuous long fiber-reinforced thermoplastic composite board, and a preparation method therefor and an application thereof. The continuous long fiber-reinforced thermoplastic composite board comprises m layers of prepreg tapes A and n layers of prepreg tapes B, and the prepreg tapes A are arranged on the outer layer, wherein m≥2, n≥1, and m and n are integers; the prepreg tapes A are continuous long fiber-reinforced long carbon chain polyamide resin unidirectional prepreg tapes that comprise continuous long fibers and long carbon chain polyamide resins; and the prepreg tapes B are continuous long fiber-reinforced short carbon chain polyamide resin unidirectional prepreg tapes that comprise continuous long fibers and short carbon chain polyamide resins. The composite board has the advantages of being low in water absorption, excellent in mechanical properties, smooth in appearance, reliable in performance and practical; moreover, the preparation process is simple, the time consumed is short, the production efficiency is high, and the cost is low.
