Prepreg is the common term for fabric reinforcement 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.

The Carbon and Fiberglass Prepregs at offer a number of specific advantages:

  • Near-perfect epoxy resin content, maximizing strength properties for the reinforcement
  • Excellent surface finish, engineered to be less porous at the surface
  • Room temperature storage, making them easier to keep and handle, without the need to thaw required of frozen prepreg options.

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.
