Manufacturing of wind turbine blade by electron beam curing

These materials have been fabricated by thermal curing process. However, thermal curing process has several disadvantages such as long curing time, large residual stresses. In order to avoid weakness of thermal process, the radiation curing process using UV, microwave, x-ray, y-ray and electron-beam is widely used in recent years. In comparison with the thermal-curing, radiation curing process does not need to thermal and autoclave equipment and have several advantages : dramatically reduced curing time : enhancement of part quality and performance : reduced environmental and health concerns : easy material treatment : significantly reduced overall manufacturing costs. This study describes novel synthesis of epoxy acrylate resin that was cured by electron-beam without photo-initiators. The effect of catalyst and synthetic temperature was investigated by molecular weight and chemical structure through GPC and NMR. E-beam cured resin showed significantly higher flexural strength and tensile strength than other commercial resins. The wind turbine wind turbine was fabricated by E-beam curing, using novel epoxy acrylate resin with fiber reinforced plastics (FRP). E-beam curable novel synthesized resin can be a good candidate in the wind turbine and in various industrial fields where high performance was required
