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.
Carbon fiber prepregs are made of high-strength, lightweight carbon fiber materials that are infused with a resin matrix. They are known for their high strength-to-weight ratio and are often used in the construction of lightweight, high-performance structures such as aircraft, racecars, and sporting goods.
Fiberglass prepregs are less expensive and less stiff than carbon fiber prepregs, but still offer good strength-to-weight ratio and are often used in the construction of a wide variety of products such as boats, recreational vehicles, and wind turbine blades.
Our room temperature carbon fiber and fiberglass prepregs offer a few 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.
UV prepregs are offered in Vinyl Ester and non hazardous Epoxy. These prepregs are formulated to cure with UV light indoors or direct sunlight within minutes.
- Very long work time as long as UV barrier remains in place - this will not cure without UV
- Rapid cure under UV- patches are ready to paint in less than 10 minutes
- Cure independent of temperature- suitable for applications from -20°F to 120°F
