摘　　要：详细介绍了热固性碳纤维编织复合材料C形结构的热隔膜成型工艺。测量了CYCOM970/PWC-T300预浸料在60~120℃不同温度下的滑动摩擦系数。采用烘箱固化和热压罐固化两种方式,进行了热隔膜预成型体的固化试验。通过对试件进行三维激光扫描,得到了C形结构隔膜成型体的厚度、回弹大小分布规律以及滑移角的大小。通过对截面进行扫描,得到了成型试件的孔隙率。The process of hot diaphragm forming for thermosetting carbon woven fabric composite with C-shaped structure is introduced in detail. The coefficient of frictional slipping between layers of the prepreg（ CYCOM970 /PWC-T300） were measured under 60 to 120 degrees with 10 degrees increment. And,the curing experiments of hotdiaphragm formed components were carried out in oven and autoclave. Furthermore,the values of slipping angle,thickness and springback of C-shaped structure formed by hot diaphragm forming were obtained by means of 3D laser scanning. In addition,the porosity ratios were determined by section scanning.
