Table 1.
Quasi-static tensile strength and stiffness of wide (left) and narrow (right) straps. The fibre parallel elastic modulus E11 [GPa] was calculated following [17] and was measured with strain gauges (E11_SG) and a linear encoder (E11_LE). The composite strains at failure εcf [%] were measured with the strain gauges. Wide straps are labelled with B, R or T, depending on the author who manufactured them, followed by the number of the strap. Narrow straps are labelled with BN and the number of the strap.
