“…A comparison between the deformability L M of potential lightweight materials for application in compliant mechanisms is given in ref. [4] Due to their high stiffness, the usefulness of metals as compliant hinge element is rather limited. In comparison nonreinforced polymers such as EP or PP-systems can sustain much greater strain.…”

“…By the choice of reinforcing fibers for the hinge system elements with higher deformations (coupler and driven element), glass fibers are preferable to carbon fibers as glass fibers have relatively high strength and lower stiffness. [4] A further increase of the deformability can be achieved by modifying the textile reinforcement. Woven or knitted fabrics provide higher deformability compared to that of unidirectional noncrimped reinforcements.…”

Compliant mechanisms are single-piece structures obtaining their desired motion through elastic deformation of flexible parts. The performance of compliant mechanisms is highly dependent on the material properties, which have to be characterized over a wide range of loads. Textile glass fiber reinforced polypropylene is identified as valuable material for compliant structures. The material properties and damage phenomena for tension, shear and compression loading as well as for cyclic loading are elaborated under special consideration of elastic and inelastic deformations. Local strain measurements in the vicinity of an open hole sharpen the validity of homogenized models for textile reinforcements and directing towards multi-scale approaches for a localized deformation analysis.
