ELASTIC RESPONSE OF POST-CONSOLIDATED AND IN-SITU CONSOLIDATED LAMINATED CYLINDERS

This paper aims to investigate the effect of interactions between the various processing variables through the application of a generalized plane deformation analysis for predicting the thermoelastic response o f post-consolidated filament-wound cylinders, to post- and in situ con solidated cylinders. The theory has been enhanced significantly to mod el the effects of winding tension in the in situ process and the redis tribution of stresses resulting from the removal of the mandrel at any point in the process. The thermal stresses resulting from post- and i n situ consolidation of an IM7/PEEK cylinder are compared. The enhance d capability of the model is then used to investigate the interaction between the cylindrical part and the tool(mandrel) and also the effect of winding tension on the residual stresses in the cylinder.
