Table 2.

Straps tested for their residual strength and stiffness properties after 1, 2, 3 and 11 million load cycles at an upper stress level (σ_u) of 720–750 MPa. The fibre parallel elastic modulus E₁₁ was calculated from linear encoder measurements (E_{11_LE}). Straps are labelled with B or R, depending on the author who manufactured them, followed by the number of the strap.
