FIBRE-REINFORCED COMPOSITE MOULDING AND MANUFACTURE THEREOF

摘要

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.
