Abstract

Polymer composites are today widely used for aerospace components in view of their outstanding specific stiffness and strength to weight ratio. This paper provides details related to the design of a carbon composite hollow torque transmission tube for a pre-specified value of torque, geometrical constraints and torsional rigidity, which could be useful as a power take off (PTO) shaft segment. This paper also gives the details of the test rig designed and fabricated for the purpose of testing composite hollow tubes. The test results provide details related to torsional rigidity and torsional deflection as a function of load. The composite tubes were fabricated using filament winding technique. The study has indicated possibility of using carbon composites for typical aerospace component like a torque transmission tube with weight and cost benefits without compromising on the shaft dynamics. Experiments were also conducted to study the effect of ballistic damage on the composite shaft and also the damage tolerance related to misalignment. This effort has provided enough confidence level in attempting the replacement of existing metallic shaft by composite shaft for PTO shaft application.
