Pre-Preg Ideal For Special, Low-Volume Parts

This is a more labor-intensive process that uses a fiberglass material that contains the resin in the cloth, known as pre-preg material. It’s most commonly processed by carefully hand-laying many layers of material in a mold and de-bulking, which removes voids. The mold is then placed in a vacuum bag and cured. This process is typically used for unusual geometry and low volume.
