Abstract

The anisotropic flow behaviour of glass fibre/polypropylene glass mat thermoplastic (GMT) has been investigated using axisymmetric squeeze flow testing between parallel circular plates. The material has a continuous swirled fibre mat construction and is manufactured by the melt-impregnation technique. Constant plate velocity squeeze flow tests have been carried out under isothermal conditions to cover a range of strain rates. Modelling of squeeze flow behaviour has been based on two simple expressions: one assumes pure shear flow during testing, while the other assumes pure biaxial extension (plug flow). The modelling results suggest that biaxial extension dominates the isothermal squeeze flow process, with apparently negligible shear flow effects.
