A model was proposed to predict residual stresses in thermoplastic composite cylinders fabricated using in-situ consolidation processes. A series of poly-ether-ketone-ketone (PEKK)-based glass and graphite composite cylinders with various layup constructions were fabricated to verify the residual stress predictions. The resin viscosity and storage modulus of the polymer were measured for analysis. A "split ring experiment" shows a fairly reasonable agreement between the predictions and test data from an application point of view.
