摘要: 复合材料已在航天领域得到广泛使用,目前采用湿法预浸料制备大壁厚复合材料蒙皮的成型周期长,产品内部孔隙率相对更高,对航天器可靠性、稳定性不利。本文以双真空固化工艺为例,对复合材料蒙皮的制备过程进行优化,通过无损探伤、截面微观质量与孔隙率三个方面对产品内部质量进行评价,结果表明,经过双真空固化工艺试验,4 mm壁厚蒙皮产品孔隙率能够控制到1.65%,内部质量得到提升。

Abstract: Composites are widely used in aerospace field. Thick composite skins made from solution prepared prepreg experienced long production period, which have higher porosity that against the spacecrafts. The article takes double-vacuum curing technique for example, and optimizes the preparation process of composite skins. The internal quality was evaluated by nondestructive testing, section microscopic quality, porosity. The result indicates that the porosity of a 4 mm thick composite skin was controlled to 1.65% and the internal quality was promoted by double-vacuum curing technique.

Key words: solution prepared prepreg, double-vacuum curing technique, porosity, composites
