Abstract

Abstract: Automated lay-up of prepregs is a crucial processing technique for manufacturing high-performance composites in aerospace industry. The quality, efficiency, and stability of automated lay-up is significantly influenced by the processing properties of prepregs, which are commonly evaluated by tackiness and drapability. This article provides a description of the formation of prepreg tackiness and an analysis of internal and external influencing factors as well as the mechanism. The major quantitative testing methods for tackiness and the domestic current progress in manufacturers and applications are summarized. And the application prospect on prepreg tackiness is outlined.

Key words: automated lay-up, prepreg, tack, quantitative test, composites
