Carbon Fibers and CFRP | SGL Carbon
Carbon fiber-reinforced plastic (CFRP) and glass fiber-reinforced plastic (GFRP) differ primarily in the use of different fibers. As the name suggests, carbon fibers are used for CFRP, whereas glass fibers are used for GFRP. Plastics based on carbon fibers have a significantly higher strength and are also lighter due to their lower density.
