COMPOUND FIBER-REINFORCED PLASTIC AND REINFORCED PANEL

PROBLEM TO BE SOLVED: To provide a compound fiber-reinforced plastic having a linear expansion coefficient equivalent to a linear expansion coefficient of an inorganic crystal molding for scintillator, lightweight, and equipped with excellent mechanical characteristics. SOLUTION: The compound fiber-reinforced plastic is composed of laminating at least two inorganic fiber prepregs having different linear expansion coefficients. The linear expansion coefficients have anisotropy. A linear expansion coefficient of a specific direction is not less than 3 ppm/K and not more than 40 ppm/K, which is larger than a linear expansion coefficient of a direction orthogonal to the specific direction. The tensile strength is not less than 70 MPa. COPYRIGHT: (C)2011,JPO&INPIT
