Curing

Curing is the irreversible change in the physical properties of a thermosetting resin brought about by a chemical reaction, condensation, ring closure, or addition. This article discusses the material types and functions of various components considered in the preparation for curing. It presents a discussion on the major elements of an autoclave system, namely, pressure vessel, gas stream heating and circulation sources, gas stream pressurizing systems, loading systems, and vacuum systems. The article describes a computerized approach to the simultaneous control of materials reaction behavior and consolidation dynamics, using an autoclave as the reaction vessel.
