摘要

In the transport and industrial sectors, moving parts and kinematics play an important role. In this context, weight savings and a reduced number of joints of moving parts are essential factors, enabling lowered fuel consumption and precise dynamic movements of machine parts. Hence, single-axis and intrinsic adaptive fiber-reinforced plastic (FRP) components with structurally integrated actuators can replace conventional moving parts. Thus, this paper aims at presenting shape-variable, adaptive FRP based on shape memory alloy (SMA) hybrid yarns. In order to protect the matrix from direct contact with SMA, to ensure free and even mobility of SMA in FRP, and to fully exploit the deformation capability of SMA and therefore the adaption potential of the entire FRP structure, wire-shaped SMA was converted into textile-based actuators in a core-sheath structure. The functionalized preforms were developed by means of weaving technology. The SMA hybrid yarn was introduced into the woven fabric structure in the watp direction. Subsequently, the functionalized preforms were infused. The adaptive FRP were characterized in terms of their deformation behavior with fully and partially sheathed SMA in lengths of 240 mm and 120 mm, respectively. Results revealed that adaptive FRP with fully sheathed SMA deform stronger than those with partially sheathed SMA.
