DEVELOPMENT OF ADAPTIVE FIBER-REINFORCED PLASTICS BY OPEN REED WEAVING TECHNOLOGY

摘要

Adaptive fiber-reinforced plastics (FRP) contain actuators that enable the controlled modification of system states and characteristics. The textile-technical integration of actuators, in particular shape memory alloys, into reinforcing fabrics has increasingly been applied in recent years. The objective is to achieve optimum force transmission from shape memory alloy to FRP, long-term stability of the adaptive FRP as well as a maximum degree of deformation. This paper presents the development of adaptive FRP, where the shape memory alloys are integrated into reinforcing fabrics by means of open reed weaving technology. After infusion of the functionalized reinforcing fabrics, the deformation behavior of adaptive FRP was electro-mechanically characterized. Results revealed that in this particular study, the maximum deformation of adaptive FRP was achieved at a voltage of 10 V and 40 s of thermal induced activation of shape memory alloys.
