The functionalization of fiber-reinforced plastics has been improved continuously in recent years in order to broaden their application potential. By using shape memory alloys in fiber-reinforced plastics, adaptive fiber-reinforced plastics can be developed, which in turn can change their shape depending on the activation of shape memory alloys. In order to ensure the proper force transmission from shape memory alloys to fiber-reinforced plastic, these shape memory alloys need to be integrated into the reinforcing fabric. Hence, this paper presents the application of open reed weaving technology for the development of functionalized preforms for adaptive fiber-reinforced plastics. For an optimized shape memory effect during their thermal induced activation, the shape memory alloys were coated with release agent and then integrated into the woven fabric by open reed weaving technology. The hinged width of functionalized preforms was varied from 50 mm to 150 mm. These preforms were infused by a thermosetting resin matrix system with a modifier. Subsequently, the electro-mechanical testing of adaptive fiber-reinforced plastics was executed. Results show that the maximum deformation of adaptive fiber-reinforced plastics was proportional to their hinged width.

开筘编织技术开发形状记忆合金基自适应纤维增强塑料

近年来，纤维增强塑料的功能化程度不断提高，以拓宽其应用潜力。通过在纤维增强塑料中使用形状记忆合金，可以开发适应性纤维增强塑料，进而可以根据形状记忆合金的激活改变其形状。为了确保从形状记忆合金到纤维增强塑料的适当力传递，这些形状记忆合金需要集成到增强织物中。因此，本文介绍了开筘编织技术在开发适应性纤维增强塑料的功能化预制件中的应用。为了在它们的热诱导激活过程中优化形状记忆效应，形状记忆合金涂有脱模剂，然后通过开筘编织技术集成到机织物中。功能化预制件的铰接宽度从 50 毫米到 150 毫米不等。这些预制件由具有改性剂的热固性树脂基质系统灌注而成。随后，执行了适应性纤维增强塑料的机电测试。结果表明，自适应纤维增强塑料的最大变形与其铰接宽度成正比。
