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: (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.

Abstract: Mechanically attaching articles made from composites has problems due to the difference in properties of the composite in the x, y planar direction and the z perpendicular direction, this results in different properties between the composite and the attachment member such as differences in coefficients of thermal expansion which can weaken the joint further leading to differences in moisture uptake which can further reduce the strength and robustness of the joint. The invention relates to the selection of the position of a joint in order to reduce such problems and to operating the moulding process in a way that improves the provision of mechanical attachments such as bolt holes.
