COMPOSITION FOR LIGHTENED AND TRANSPARENT COMPOSITE METHOD FOR PREPARING THE COMPOSITES USING THE SAME AND THE COMPOSITES PREPARED THEREBY

摘要

More specifically, the present invention relates to a glass fiber reinforcing material (A) having a refractive index of 1.4 to 1.6 and a glass fiber reinforcing material having a refractive index different from that of the glass fiber reinforcing material A lightweight transparent composite material excellent in impact resistance, scratch resistance, weather resistance, and high rigidity can be provided by thermally curing the curable resin (B) of -0.005 to +0.005. In particular, when the lightweight transparent composite material according to the present invention is applied to a transparent window of an automobile, improvement in automobile fuel consumption, lowering of the center of gravity of the vehicle can be expected, and more rigid steering can be expected. have.
