An experimental procedure is being developed to simulate the thermoplastic pultrusion process. A compression molding die has been designed to produce a part with the same cross-sectional geometry as the pultrusion machine being developed. Processing variables such as heating and cooling rates, pressure profiles and fiber tension may be varied to simulate the pultrusion fabrication. Processing equipments can be conducted quickly on a relatively small amount of material. Results of the experiments may be useful in determining a range of acceptable processing parameters for each material system before it is brought on line. Knowledge of acceptable processing cycles can be used with the theoretical thermoplastic pultrusion process models under development to design appropriate heating and cooling systems as well as an optimized die cross-section. These efforts will hopefully lead to components with acceptable mechanical properties and appearance which have been pultruded at high speed. To date, attempts at high speed thermoplastic pultrusion have met with limited success.
