摘要: A reinforcement for a fiber reinforced plastic which is a mixed-woven or knitted fabric of two kinds of filaments is disclosed. One kind of filament thereof is an ultra high molecular weight polyethylene filament having tensile strength of not less than 20 g/denier and tensile modulus of not less than 500 g/denier and the ultra high molecular weight polyethylene filament material occupies 60 to 90% of the total surface area of said fabric. The filament other than the ultra high molecular weight polyethylene filament occupies 60 to 90% of the total back surface area of the fabric. There is also disclosed a fiber reinforced plastic comprising a first reinforced resin layer reinforced with the above reinforcement and a matrix resin, and a second reinforced resin layer reinforced with an inorganic fiber and a matrix resin, the first reinforced resin layer being laminated on at least one surface of the second reinforced resin layer in such a manner that the back surface of the first reinforced resin layer faces to the second reinforced resin layer.
