Abstract: Process for producing a composite material comprising depositing a prepreg containing a radiation initiated curing agent onto a mould using automated apparatus and applying heat and second source radiation to at least partially cure the prepreg at least simultaneously with the deposition of the prepreg. Also epoxy resin formulations of a mixture of a liquid epoxy resin and a solid or semi-solid epoxy resin containing a photoinitiator are used as the matrix in prepregs which are cured or partially cured by radiation to avoid the need for thermal cure in an oven. The formulation is particularly useful in the production of wind turbine blades especially in an automated process. Additionally an automated tape laying apparatus comprising compaction device, a heat source and a second radiation source.

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.
