摘要：
Squeezing flow of glass-mat reinforced thermoplastics (GMT) material was carried out in this research study to investigate the structure and reorientation of the fibre reinforcement and to develop a better understanding of the material's rheological behaviour. Circular disks of GMT material were squeezed to different final thicknesses, always forming an elliptical shape, and three-point bending tests were carried out on each specimen in the two main directions. The mechanical properties of the specimens confirmed the fibre rotation predicted by Jeffery's equation. It is shown that the fibres rotate in a manner aligning themselves in the major direction of the flow, which makes the material less anisotropic as the flow proceeds.
