Impact resistant fiber-reinforced composite material

Impact resistant fiber-reinforced composite material has a tensile strength of 17cN / dtex or more, a tensile fiber sheet 2 to which the elastic modulus is formed in 450cN / dtex or more high strength fibers f, impact resistant fiber and a matrix resin 3 in reinforced composite material 1, as the matrix resin 3, an ethylene - an ionomer resin crosslinked with a metal ion between molecules of the methacrylic acid copolymer, containing 3 to 100% by weight relative to the fiber f. Impact resistant fiber-reinforced composite material is excellent in ballistic performance for protecting the human body from a high-speed projectile, such as 耐刃 performance and projectile and debris against knives and, lightweight, stab vest, body armor, bulletproof helmets, clothing for protection part of the body such as stab gloves and the entire blade, the bullet Guzai also, batons, 警杖, two-pronged weapon for catching a criminal, shields such as portable protective gear, furthermore, used vehicle, watercraft, aircraft, etc. helicopter armor, can be suitably prepared and bulletproof plate.
