This process is designed to produce semi-finished fabrics, or unidirectional fiber tapes, impregnated with an uncured resin. Because the prepregs present a certain level of tack, they are rolled with a protective layer.
Prepregs can be manufactured in the following ways:
1. Solvent Process
2. Hot-Melt Process
3. B-Staging Process
Prepregs are typically cured in an autoclave or using an out-of-autoclave process (compression molding).
