Vacuum Bagging with Prepregs Processes Many Benefits

Prepreg processing is an out-of-autoclave composites manufacturing process that is used to make precision composites parts with reduced costs and emissions. The most common prepreg processing technique is vacuum bagging, used by industries including aerospace, marine, automotive, and wind energy. Prepreg processing is useful for high-demand applications where performance, weight, and mechanical properties are critical.

Prepreg processing involves plies of prepreg materials that are laid up using various methods, with several consumable products layered on top, then consolidated under vacuum bag pressure. The curing process is triggered by the application of heat in a heated tool, oven, or autoclave where heat and high pressure are applied. The temperature and curing cycle vary depending on the materials used and end application requirements.

High-end thermoset or thermoplastic resins are used in the prepreg processing composites manufacturing method, along with a fully impregnated carbon fiber, glass fiber, aramid, or other advanced fiber. The vacuum bagging process and curing cycle achieves a low void content in high-quality composite parts for critical structural applications.
