The main challenges with composite parts manufacturing are related to the curing means, mainly autoclaves, the length of their cycles and their operating costs. In order to decrease this dependency, out of autoclave materials have been considered as a solution for high production rate parts such as spars, flaps, etc… However, most out-of-autoclave process do not possess the same maturity as their counterpart, especially concerning part quality 1. Three out-of-Autoclave prepreg materials were considered for this study, each one possessing different curing temperatures: A (180°C), B (125°C) and C (132°C). Those materials have also different chemical compositions, although all three have been designed for out-of-autoclave composite part manufacturing (primary and secondary structures). The interest of our study is to understand and compare polymerization mechanisms of each matrix, by defining each time a predictive model close to experimental values of the curing of those epoxy/amine systems 2.
