Processing Polymer Matrix Composites

Abstract

There are numerous methods for fabricating polymer matrix composite components. This article outlines some of the most common and popular ones that cover processes such as autoclave, liquid, injection and compression molding, as well as filament winding and pultrusion. Variants of these well‐established processes are also covered, highlighting key attributes brought about by new innovations to the original processes. Where appropriate, examples of composite components that are typically produced by the respective processes are also mentioned. The key composite processing variables are then discussed, and where relevant, reference is made to particular processes described earlier in the article. The variables, which include fiber form and architecture and resin type, as well as flow and cure behavior, and tooling are described with respect to their control and monitoring; how they affect the properties of the composite laminate, in relation to void content and fiber loading and directionality, after they have been processed is also discussed.
