Prepreg is the common term for carbon fiber that has been pre-impregnated with a resin system. The resin system is typically an epoxy and already includes the proper curing agent. As a result, it’s ready to lay into a mold without the addition of resin or the steps required of a typical hand lay-up.
Why choose prepregs over standard fabric reinforcement and the wet lay-up process?
- Improved cosmetics. No accidental drips of resin or dry spots to compromise appearance or performance.
- Repeatable, uniform parts. Consistent resin content means prepreg parts that come out of a mold can, in theory, be identical.
- Improved efficiency in the process. Prepregs translate to savings on wasted product, supplies, and time spent on wet lay-up and clean-up.
- Reduced cure time. After the necessary heating cycle for cure is complete, prepreg parts are ready for service without additional waiting time.
