Carbon Fiber Reinforced Plastic
Carbon Fiber, or carbon fiber-reinforced plastics (CFRPs) are much like fiberglass, except that the fiber used is carbon fiber.
The resulting product is a very stiff and strong material.
The fibers themselves look like shiny black hair, but much tinier upon closer inspection. They will blister hands, even those with latex gloves. Actually this is less annoying than glass fibers, which will guarantee a week of suffering.
