A thermoplastic CFRP sheet with an excellent balance of mechanical properties and press molding workability, as well as high suitability for high-volume production through press molding, has been developed for vehicles. This material consists of a mat of discontinuous, in-plane randomly oriented carbon fiber impregnated with thermoplastic resin. Thorough the use of press molding, consistent quality is achieved while allowing for excellent workability; the product is also well suited for mechanical simulation due to its high homogeneity.
