Recent studies on ROS, with high fibre volume fractions (>50%),
have shown interesting forming and mechanical characteristics
[4–11]. However, to the best knowledge of the authors, the major
achievements were mainly on the prediction of ROS mechanical
properties [4], but there are no predictive models to simulate the
forming mechanisms. This paper focuses on the flow mechanisms
governing the processing of ROS thermoplastic composites by
compression moulding
