The influence of several mixing settings on the mechanical properties were studied. A Long fibre thermoplastic glass polypropylene material was mixed, compression moulded and analysed by flexural tests and charpy impact. In a low-shear mixing machine, chosen for limited fibre length degradation, six parameters were varied for a set of experimental work: fibre fraction, fibre length, processing temperature, mixing time, mixing speed and filling ratio of the cavity. Experimental results are in line with the predictive model of Tandon-Weng for stiffness and show a similar trend as the Kelly-Tyson model for strength. Little influence of the varied process parameters is seen, indicating the robustness of the process.
