3.1.1. Mechanical characteristics of the implants
P4HB scaffold and PP mesh exhibited similar behaviour under cyclic uniaxial load (Figure 2) with a strong inelastic deformation in the first cycle, followed by a fast stabilisation. However, the membrane stiffness of the PP mesh is threefold higher compared to P4HB scaffold within ten cycles. A decrease in the stiffness of the PP mesh was observed after 10 cycles contrary to the P4HB scaffold which exhibited a relatively small increase in its stiffness after cyclic mechanical loading (17).
