Abstract

Carbon-fibre-reinforced cylindrical rods with a biocompatible epoxy matrix subjected to torsion load were investigated. Three kinds of manufacturing processes were used for these rods: hot-pressing as well as winding for unidirectional rods and a combination of winding and braiding. The properties of two kinds of composite rods were determined: one with braided-fabric and another without braided-fabric. Shear fracture tests were conducted with a specially-developed torsion loading facility. The corresponding fractography and deformation behaviour were analysed. The effect of loading rate on shear performance of the rod was also studied. The experimental results led to the conclusion, that owing to the three-dimensional reinforcement effect of braided-fabric, the overall performance of polymer composite rods with braided-fabric is much better than those without braided-fabric.
