Abstract: This invention relates to a use of a non-woven thermoplastic resin in combination with a curable moulding material comprising a fibrous reinforcement material and a thermoset resin material by bringing the thermoplastic resin in contact with the curable moulding material during or following assembly of the moulding material. The thermoplastic resin has a melting point below the gel temperature of the thermoset resin material to reduce the void fraction and increase the ILSS of a cured moulding manufactured from said moulding material forming a laminate structure in comparison to a cured moulding manufactured from said moulding material in which the fabric is absent forming the laminate structure.

Abstract: A moulding material which comprises: (a) a structural reinforcement layer comprising a fibrous reinforcement material optionally in combination with a second resin composition; and (b) a surface enhancing layer, for contacting a surface of a mould or tool, comprising a first non-woven fibre carrier in combination with a first resin composition containing a rheology modifier and a curing agent, wherein the first resin composition provides an external mould or tool-contacting surface of the moulding material. The moulding material can be cured to form a moulded article having a high quality surface finish that requires minimal preparation before painting and/or application in its intended use. The moulded article may be provided with sacrificial discontinuous indicator means to assist in uniform removal of a part of the surface enhancing layer of the moulded article for specific applications.

Abstract: An improved surface finish on articles moulded from prepregs is obtained by providing a surface finishing film on the surface of the prepreg and a surface venting layer on the surface of the surface finishing film in which the finishing film comprises a flowable tacky resin and the venting layer contains perforations which allow passage of the resin through the venting layer to provide removable adhesion between the surface of the mould and the moulding composition during moulding.

Abstract: (57) Abstract: The present invention concerns a process for the production of wind turbine structures. In the process, a stack of prepregs is located inside a vacuum bag. Each of the prepregs comprises a mixture of fibrous reinforcement and from 20% to 85 wt % of an epoxy resin of EEW 150 to 1500 and containing from 0.5 to 10 wt % of a curing agent. The curing agent comprises a urea curing agent and an imidazole curing agent, and is free of dicyandiamide. The epoxy resin is cured by application of an externally applied temperature in the range 70° C. to 110° C. for a period of from 4 to 8 hours.
