The present invention relates to the use of a low Tg compatible resin as an adhesive layer for welding a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is particularly good for welding large components, such as wind turbine halves and spar caps. Useful thermoplastic composites are thermoplastic composites formed by infusing long fibers with a reactive acrylic liquid resin system, such as an ELISUM resin system from Arkema, and curing.
本发明涉及低Tg相容性树脂作为粘合剂层用于将热塑性复合结构焊接到热塑性或热固性结构上的用途。本发明对于焊接大型部件,例如风力涡轮机半件和翼梁帽尤其好。有用的热塑性复合材料是通过用反应性丙烯酸类液体树脂体系,例如来自Arkema的ELIUM®树脂体系灌注长纤维并固化形成的热塑性复合材料。
