A carbon fibre reinforced substrate comprises a fabric of carbon fibre strands, and a first resin adhered to the substrate, wherein the strands are made of continuous carbon filaments. The fibre strand has a tensile elasticity of 210GPa or higher, breaking strain energy of 40MJ/m 2> or higher. The amount of the first resin is 1-20 parts by weight per 100 parts by weight of the fabric. Independent claims are also included for: (1) a pre-form obtained by laminating multiple layers of the substrate integrated by applying resins; and (2) a composite material comprising the pre-form and a third resin.
