Latest Patents

Mikio Shima holds a patent for a unidirectional prepreg and carbon fiber reinforced composite material. This invention enhances the compressive strength and compression strain at failure of pitch-based carbon fiber reinforced composites by integrating polyacrylonitrile-based carbon fibers. The pitch-based carbon fibers exhibit a tensile modulus of not less than 400 GPa and a tensile strength of not less than 2000 MPa. The compressive strength of this unidirectionally reinforced composite material ranges from 100 MPa to 800 MPa, with fiber diameters between 4 µm and 15 µm. The polyacrylonitrile-based carbon fibers provide superior compressive strength and compression strain at failure compared to the pitch-based fibers, with a smaller fiber diameter.
