CARBON FIBER REINFORCED BASE MATERIAL,PREFORM AND COMPOSITE MATERIAL COMPRISING THE SAME

摘要

A carbon fiber reinforced base material which has a fabric comprising carbon fiber bundles and a first resin adhered to said fabric,characterized in that the carbon fiber bundle comprises a lot of continuous carbon filaments,has a tensile elastic modulus of 210 GPa or more and a breaking strain energy of 40 MJ/m3 or more,and said fabric has the first resin adhered thereto in an amount of 1 to 20 parts by weight relative to 100 parts by weight of the fabric;a preform prepared by laminating a plurality of sheets of the carbon fiber reinforced base material and forming them in one piece through the first resin;and a composite material prepared by impregnating the preform with a matrix resin,followed by forming.
