Simulation accounting for the effect from interlaminar molten resin
When modelling the forming of a multi-layer pre-preg, in order to accurately predict forming defects, such as wrinkles, it is important to represent not only the in-plane and out-of-plane material properties, but also the interlaminar sliding resistance.
Contact options for composite materials
- Interfacial normal direction: Account for adhesion and peeling behavior
- Interfacial section line direction: Define pressure, velocity, and temperature dependent friction

Interlaminar friction test
By importing sliding test results, users can create a model which accounts for the normal pressure, pull velocity and temperature dependent sliding resistance.
