Tenax® Prepreg comes in various forms, such as unidirectional, woven, and slit tape. For special applications thermoplastic prepreg is also available.

Prepreg is made by impregnating fibers, such as carbon fiber, glass fiber, and aramid fiber, with uncured thermosetting resins (epoxy resins). This material can be found in many familiar products such as golf club shafts and fishing rods. It can also be found in cutting-edge ACMs (Advanced Composite Materials) for rockets and aircraft.
