Abstract
The effect of cooling rate from the molten state and annealing from the amorphous state on thermal and crystallization residual stress development in graphite fibre reinforced polyetheretherketone (APC-2) laminates is studied experimentally by measuring the radius of curvature developed in (0/90) unsymmetric laminates. Curvature is measured for cooling rates ranging from 1.5°C/min to 8000°C/min, and for annealing temperatures ranging from 175°C to 250°C. Stress relaxation effects are also quantified.
