Abstract: A prepreg for manufacturing a fibre-reinforced composite material, the prepreg including a body having a layer of fibrous reinforcement impregnated with a matrix resin material, and a powder coating layer of resin material on at least one major surface of the body and at least partly fused to the matrix resin material

Abstract: The present invention provides a moulding material (100) comprising at least one dry fibrous reinforcement layer (102, 103) having a surface resin material (106) conjoined to a first surface thereo and a structural resin material (101) conjoined to a second surface thereof wherein the structural resin material is provided with a recess (107) which is free from resin and is located at the edge of the structural resin layer (101) and wherein the dry fibrous reinforcement layer (102, 103) provides a venting structure to allow entrapped air to pass out during processing. The material of the present invention can be used to form a composite which can be used as surface coating for large components such as wind turbines.
