ProComp® Carbon Reinforced Polypropylene

ProComp® is a patented high-pressure laminated prepreg composite that is available in stable sheet form exclusively from Curbell Plastics.

The proprietary composite manufacturing process infuses high strength carbon fibers into the structure of the hybrid laminate. The patient is thus protected from dermal contact with the carbon fibers as the surfaces of the laminate are void of carbon fibers. The high-pressure laminated prepreg composite is comprised of layers of a thermoplastic resin and carbon fiber, and is compatible with post-delivery adjustments to the clinical device without a decrease in structural integrity of the composite. 

The advanced proprietary high-pressure lamination process allows the ultra-light carbon composite to be compatible with standard vacuum drape and bubble forming techniques commonly used for the custom fabrication of lower limb orthoses and prosthetic sockets.
