Zusammenfassung: | The present invention discloses a thermoplastic carbon fiber composite material structure and its manufacturing method. First, a thermoplastic fiber is made into a first thermoplastic non-woven fiber layer. Next, an air-laid machine is used to comb the carbon fiber to produce fibers in a two-dimensional or three-dimensional direction that fall on the first thermoplastic non-woven fiber layer to form a carbon fiber layer. Finally, the second thermoplastic non-woven fiber layer is formed on the carbon fiber layer to form a carbon fiber composite material felt with a three-layer structure. Then a hot-pressing molding machine is used to perform hot pressing to form and fix the carbon fiber composite felt for subsequent product processing and use. The invention can effectively solve the problem of incomplete impregnation of carbon fibers after hot-pressing molding of thermoplastic carbon fiber composite materials, and can effectively improve the quality of end products because the mixing of carbon fibers and non-w |
