Abstract:Press forming of thermoplastic textile composites is a
fast and efficient method of production. Friction
occurring between the composite material and pressure
blank-holder during forming imparts tensile stresses in
the sheet which help counteract compressive stresses
generated by material deformation; stresses that can
result in unwanted wrinkling of the forming sheet. In
order to model the press forming process and optimise
boundary conditions, this friction behaviour must be
characterised and modelled. Two different test methods
are employed to characterise the friction and two
complementary modelling strategies, an empirical and a
predictive approach, are presented.
