“…The improved fatigue strength can better protect the xUHPE blend from failures of the propagation of subsurface cracks, such as local fractures, delamination, and/or pitting of the polymer component. 30 The above results reveal that in comparison with CM UHMWPE, the comprehensive properties of the xUHPE blend are signicantly improved. The marked augmenting of the ultimate tensile strength and Young's modulus makes it possible to endure strong external loading when used as an in vivo joint, and the increased impact strength of the xUHPE blend is benecial for stress transfer through plastic deformation.…”
