Modeling the interply slip during forming of thermoplastic laminates

Abstract:

Interply slip plays an important role in composite forming processes, the resulting product geometry, final fiber orientations and fiber stresses. This interply slip will depend on fiber/resin properties, the fibers distribution, the reinforcement architecture and the process conditions. In this paper, a new model, based on Reynolds equation for thin film lubrication, was developed to predict the frictional behavior of these materials. This approach should be validated by means of experiments.
