Polymer-matrix composites are processed most frequently using open or closed molding methods. Open molding processes, which use a single-sided mold to shape a composite part, include lay-up molding, spray-up molding, and filament winding. Closed molding processes, which use a two-sided mold to shape composite material, include compression, injection, reaction injection, and resin transfer molding as well as pultrusion. The type and form of matrix materials affect which processes are appropriate to use. Polymer-matrix composites are the most widely utilized composites in manufacturing. An understanding of the various processes used to create PMC parts is essential for any composite technician. After taking this class, a user will be able to distinguish between the various polymer composite processes used in manufacturing today.
