High-modulus carbon fiber composite material main frame, preparation method and preparation mold

The invention provides a high-modulus carbon fiber composite material main frame, a preparation method and a preparation mold, and belongs to the technical field of high-performance carbon fiber composite materials. The problems that a main frame bearing structure is large in mass and large in forming process difficulty are solved. The preparation method comprises the steps that (1) I-shaped beam ribs are prepared and formed through a split mold matching forming process and a prepreg laying forming process; and (2) after all the sectioning molds subjected to prepreg hair spreading are assembled together, the skin is integrally formed through the prepreg, the skin is of a surrounding structure, and the I-shaped beam ribs are supported in the front side of the skin. The forming process is simple, and is particularly suitable for a supporting structure of a space camera. 本发明提出了一种高模量碳纤维复合材料主框架、制备方法及制备模具，属于高性能碳纤维复合材料技术领域。解决了主框架承载结构质量大、成型工艺难度大的问题，本发明的制备方法为：(1)、工字梁筋采用分瓣模具对模成型工艺和预浸料铺放成型工艺制备成型；(2)、将所有预浸料铺发完成的分瓣模具组装在一起
