Abstract

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
