Incidence of the orientation of the reinforcing fibers in a carbon/epoxy composite shaft, for torsional loads and rotational speed

The study carried out is based on the analysis of the behavior of the angle-ply of a composite shaft, in terms of its resistance to torsional loads and speeds of rotation. For reference, a composite shaft of carbon fiber and an epoxy polymer matrix is optimally designed. The orientations of the laminas in the laminate were selected to ensure their manufacture by the filaments winding method. For the specific case of study, it can be concluded that the pairs of laminas with angles of 45 ° and -45 ° optimally satisfy the design parameters of the shaft. The orientations at 0 ° and 90 °, are useful when the critical speed and torsional buckling are more restrictive.
