Abstract

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
