Abstract In order to simplify and improve the existing kinematic functional range, the elimination of conventional joints and external drives as well as a reduction in the number of gear elements is required. This aim can be achieved by means of adaptive fiber-reinforced plastics (FRPs) due to their lightweight and intrinsic actuator properties. Hence, this research project presents adaptive FRPs including shape memory alloys (SMAs) that were structurally integrated into reinforcing fabrics using the open reed weaving technology. The functionalized preform for the formation of adaptive FRPs was varied by the number of interlacements with weft yarns, SMA length, and thickness ratio. For each variation, a hinged structure was developed in order to realize greater deformation. The adaptive FRPs were characterized thermo-mechanically. Results revealed that the maximum deformation of adaptive FRPs is proportional to SMA length and thickness ratio but inversely proportional to the number of interlacements.
