Influence of Fiber Orientation and Adhesion Properties On Tailored Fiber-reinforced Elastomers

This research focuses on the investigation of endless fiber-reinforced elastomeric materials with special tailoring by different fiber orientations in the composite structure. Therefore, a modified testing device including a suitable specimen production was carried out and the comparability of tests conducted at different test scales (micro- to macro testing level) was proven. Two elastic matrix materials (silicone and polyurethane) and reinforcing fiber types (glass- and polyester fibers) were investigated in all combinations. Due to the important effect on the shear behavior during the deformation of textiles significantly influenced by the fiber orientations of the warp- and weft-yarns, a testing plan was established by using one material combination as a reference setting. Generally, the results reveal a good comparability between different testing levels for the same fiber-matrix combinations and the modified composite testing device has been proven. Furthermore, the significant influence of different fiber orientations on the shear stiffness was investigated.
