Features

Lightweight CFRP products offer excellent strength and rigidity.
CFRPs are made by combining carbon fibers, either with injection molding or autoclaving, with the base plastic chosen for the end application. This gives CFRP products excellent mechanical properties (high strength and high elasticity) along with their carbon-derived properties (low density, low expansion, heat resistance, wear resistance, chemical resistance, self-lubrication, and conductivity).

Applications

CFRP products began being used in the aerospace industry, for their light weight, strength, and rigidity, and are being used in many fields, including the next-generation automotive field.

FAQ

What are carbon dry bearings?
They are carbon-fiber composite plastic bearings.
Our proprietary carbon-fiber composite plastic is made by combining very strong, highly elastic carbon fibers with strong, heat-resistant engineering plastics and then blending in additives to produce dramatically improved resistance to wear and abrasion.
Are order-made products available?
Yes. We take fully custom orders, including materials development and sizes, in addition to standard products.
