SiC-fibre reinforced titanium shafts under multiaxial loading - Tests and numerical simulations for torsion and tension loading

摘要

Based on micromechanical finite element modelling SiC-fibre reinforced shafts for torsion loading combined with low axial loading were designed. An unidirectional angle ply laminate with fibres oriented at an angle of 45° relative to the shaft axis turned out as the optimal solution. A special winding technique and hot isostatic pressing were used to produce the shafts out of SiC-fibres coated with titanium Ti-6Al4V by electron beam vapour deposition. Torsion and tension tests were carried out with these specimens and the results were compared with a micromechanic finite element model.
