The Tension-Twist Coupling Mechanism in Flexible Composites
Abstract
<p>The focus of this research is to quantify the effect of load-coupling mechanisms in anisotropic composites with distinct flexibility. In this context, the study aims to realize a novel testing device to investigate tension-twist coupling effects. This test setup includes a modified gripping system to handle composites with stiff fibers but hyperelastic elastomeric matrices. The verification was done with a special test plan considering a glass textile as reinforcing with different lay-ups to analyze the number of layers and the influence of various fiber orientations onto the load-coupled properties. The results demonstrated that the tension-twist coupling effect strongly depends on both the fiber orientation and the considered reinforcing structure. This enables twisting angles up to 25<sup>◦</sup> with corresponding torque of about 82.3 Nmm, which is even achievable for small lay-ups with 30<sup>◦</sup>/60<sup>◦</sup> oriented composites with distinct asymmetric deformation. For lay-ups with ±45<sup>◦</sup> oriented composites revealing a symmetric deformation lead, as expected, no tension-twist coupling effect was seen. Overall, these findings reveal that the described novel test device provides the basis for an adequate and reliable determination of the load-coupled material properties between stiff fibers and hyperelastic matrices.</p>
