Torsional and compressive behaviours of a hybrid material: Spiral fibre reinforced metal matrix composite

Armouring metals with strong wires or fibres is a common way of providing them with extra mechanical strength. A metal–metal composite armoured with twisted (spiral-shaped) wires is a particularly attractive option. We propose such a design that can be realised by twisting of a pre-assembled metallic matrix with embedded reinforcing fibres. An analytical model was developed to predict the torsional behaviour and the torque–twist requirements in …
