A moulding material 100 comprises at least one dry fibrous reinforcement layer 102, 103 having a surface resin material 106 conjoined to a first surface thereof 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, the dry fibrous reinforcement layer providing a venting structure to allow entrapped air to pass out during processing. The moulding material may be assembled into a composite comprising a continuous array of the materials 100, 200 such that the peripheral edge of each moulding material contacts an adjacent moulding material, overlap occurring with an elongate edge of one moulding material being received in the stepped recess of an adjacent moulding material. The composite can be used as a surface coating for large components such as wind turbines blades, marine craft hulls, ray-domes, bridges and architectural mouldings. |
