Reactive thermoplastics are advantageous for wind turbine blades because they are recyclable at end of life, have reduced manufacturing costs, and enable thermal joining and shaping. However, there are challenges with manufacturing wind components from these new materials. This work outlines the development of manufacturing processes for a thick glass fiber–reinforced acrylic thermoplastic resin wind turbine blade spar cap, with consideration given to effects of the exothermic curing reaction on thick composite parts. Comparative elastic properties of these infusible thermoplastic materials with epoxy thermoset materials, as well as thermoplastic coupon components, are also included. Based on the results of this study it is concluded that the thermoplastic resin system is a viable candidate for the manufacturing of wind turbine blades using vacuum-assisted resin transfer molding. Significant gains in energy savings are realized avoiding heated molds, ability for recycling, and providing an opportunity for utilizing thermal welding.

反应性热塑性塑料对风力涡轮机叶片而言是有利的，因为它们在使用寿命结束时可回收利用，降低了制造成本，并且能够进行热连接和成型。然而，用这些新材料制造风组件存在挑战。这项工作概述了厚玻璃纤维增​​强的丙烯酸热塑性树脂风力涡轮机叶片翼梁盖的制造工艺的发展，同时考虑了放热固化反应对厚复合部件的影响。还包括这些不溶性热塑性材料与环氧热固性材料以及热塑性试样组件的比较弹性。根据这项研究的结果，可以得出结论，热塑性树脂体系是使用真空辅助树脂传递模塑法制造风力涡轮机叶片的可行选择。通过避免加热的模具，可回收的能力并提供了利用热焊接的机会，实现了节能的显着提高。
