近年来，功能化纤维增强塑料（FRP）在轻量化应用行业中的重要性稳步增长。在本文中的设计以及实现的三维玻璃钢与集成纺织品为基础的驱动器和验证其变形行为进行了说明。这种变形是通过使用纺织加工的形状记忆合金（SMA）材料获得的。采用摩擦纺纱技术制备形状记忆合金复合纱线，以SMA为驱动芯，玻璃纤维和聚丙烯短纤维为护套，实现SMA丝在电流诱导激活过程中的最大可能运动。SMA的致动特性是通过焦耳加热实现的。为了验证SMA的驱动性能对3D FRP的变形行为的影响，改变结构构造。结果表明，自适应FRP的驱动性能与结构参数密切相关。
The importance of the functionalized Fiber Reinforced Plastics (FRP) is growing steadily in recent years in lightweight application industries. In this paper the design as well as the realization of three-dimensional FRP with integrated textile-based actuators and the validation of their deformation behavior is described. This deformation is obtained by using textile processed Shape Memory Alloy (SMA) materials. The friction spinning technology is used for the production of the shape memory alloy hybrid yarn, where the SMA acts as actuating core and glass as well as polypropylene staple fibers act as sheath in order to realize the maximum possible movement of the SMA wire within the composite during current induced activation. The actuating properties of the SMA are achieved by joule heating. In order to validate the influence of the actuating properties of the SMA on the deformation behavior of the 3D FRP, structural constructions are varied. The results show that the actuatory behavioral property of the adaptive FRP is greatly dependent on structural parameters.
