Abstract

As a major objective, the feasibility is checked of the curing of composite material parts in a small diameter autoclave. The material must respect a temperature cycle curing and different thermal constraints. The particularity of this study is the heat exchanges which are mainly free convection and radiation. The temperature profile and the reticulation conversion yield are determined in a section of the autoclave by numerical simulations at different functioning pressures and commented. An experimental investigation has been made at atmospheric pressure. The measured data well agreed with the simulated results. This study allows us to validate this autoclave designed for the curing of composite material parts. © 2004 American Institute of Chemical Engineers AIChE J, 50: 3149–3159, 2004
