| Summary: | The thermoplastic composites have advantages in excellent fatigue resistance， short forming cycle， secondary processing， weldable and no storage condition restrictions， it is significant to study the preparation and forming method of thermoplastic prepreg to realize the engineering preparation of thermoplastic composites and meet the application requirements of aerospace， rail transit， and other fields. In this paper， the preparation process of continuous fiber reinforced thermoplastic prepreg is introduced in detail， including solution impregnation， melt impregnation， film lamination， powder impregnation， suspension hot melt， and fiber mixing. At the same time， the thermoplastic composite molding process is emphatically discussed， including hot pressing molding， winding molding， automatic laying molding， in-situ consolidation molding and 3D printing molding. Meanwhile， the feasibility of the engineering application is sorted out according to the characteristics of each prepreg preparation and molding process. Finally， the future trends of thermoplastic composite are prospected， and development suggestions are given. |
