Models developed simulate (a) the manufacture of thermoplastic composite plates in an autoclave, in a press, or by tape laying, and (b) the filament winding of thermoplastic composite cylinders. The models relate the applied temperature, pressure, speed, and time to the temperature, crystallinity, consolidation, interlaminar bonding, and residual stresses and strains inside the composite. On the basis of these models, user friendly computer codes were written which can be used to generate numerical results and to select the appropriate processing conditions for a given application. Tests were also conducted to validate the models. In these tests, APC-2 graphite/PEEK plates were fabricated both in a press and with a specially constructed tape laying apparatus. The temperature, intimate contact, and bonding inside the plates were measured. The data agreed well with the results of the model.
