About Karbel Carbon

Pre-preg Carbon Specialist

At Karbel we make sure to offer our clients the best quality of selection of carbon fiber parts, as well as provide them with superb customer service.

Our products are made of dry carbon fiber, which is third generation of carbon fiber material characterized by its lightweight and strength. The dry carbon fiber fabric is weaved with resin pre-impregnated carbon fiber called “prepreg” in carbon fiber industry. Prepreg reaches optimal resin/carbon ratio to strive for its characteristics. Thus during the carbon parts manufacture process, there is no resin application needed when molding. This is why we call it Dry carbon fiber. Autoclave process is another important step to finish our product. In the autoclave, the high pressure and temperature are the key to our products tensile strength, which could be 15 times higher than steel’s. Unlike the Wet carbon fiber where the resin is applied into carbon fiber cloth to form sturdy structure, dry carbon fiber parts are generally 50% lighter than those made of wet carbon fiber, and the strength of these two materials are also different. That is why carbon inlays and interiors use wet carbon fiber.
