摘要/Abstract

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。

关键词: 碳纤维编织复合材料, C形结构, 热隔膜成型, 孔隙率, 滑移角

Abstract: 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 hot-diaphragm 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.

Key words: carbon woven fabric composite, C-shaped structure, hot diaphragm forming, porosity ratio, slipping angle
