Abstract:
A hybrid material comprising:a substrate prepared by curing a fabricated material made of a mixture of one or more kinds of organic binders and at least one kind of inorganic powders; andat least one unidirectional fiber layer which is comprised from one or more kinds of fibers, adhered to at least one of outer surfaces of the substrate by resin impregnation,wherein E.sub.f /E.sub.s satisfies the following relational formula (1) and E.sub.f .multidot.t.sub.f /E.sub.s .multidot.t.sub.s satisfies the following relational formula (2),E.sub.f /E.sub.s >1 (1)E.sub.f /E.sub.s .gtoreq.E.sub.f .multidot.t.sub.f /E.sub.s .multidot.t.sub.s .gtoreq.0.15 (2)where E.sub.f is bending modulus of elasticity of the resin impregnated unidirectional fiber layer, E.sub.s is bending modulus of elasticity of said substrate, t.sub.f is thickness of resin impregnated unidirectional fiber layer and t.sub.s is thickness of said substrate.
