PURPOSE:To obtain a composite material having a good abrasion resistance which shines continuously in a dark place by projecting light by forming it by mixing ceramic grains and grains of inorganic light emitting material in resin having light transmittance. CONSTITUTION:For a composite material 1, ceramic grains 3 and grains 4 of organic light emitting material are mixed in resin 2. In this case, the resin 2 is provided with transparency or translucency, the ceramic grains 3 is provided with a light transmittance such as in glass, and they are used in the form of grains. For the grains 4 of inorganic light emitting material, a material which absorbs and accumulates radiated electromagnetic waves of a specified wavelength preliminary, converts these into light, and emits visible light continuously for a long period by itself is used. The material can thus shines by a projection of head lamp, etc., and keep shining continuously thereafter. |
