Nippon Carbon CCM Series C/C Composite

Manufacturer: Nippon Carbon Co., Ltd.
Model: CCM Series

Features

CCM^® is a lightweight carbon material that has high strength and elasticity, reinforced with carbon fibers.
Since both the reinforced fibers and the matrix are composed of carbon graphite, CCM maintains carbon’s superior properties.
