Contribution of thermo-mechanical parameters and friction to the bonding of thermoplastic tapes in the tape winding process

Ensuring a good inter-laminar bonding while accelerating the production in the tape winding process of thermoplastic tapes is a key question. Finite element models and numerical simulation help to predict the influence of process parameters on the product quality. This article addresses the finite element modeling of the thermal and mechanical phenomena involved in the tape winding process of thermoplastic tapes. It highlights through simulation and experimental validations the influence and necessity to promote the friction between the different components on the product quality and the process itself. This parameter is neglected in the literature which focuses mainly on thermal parameters and occasionally on the mechanical parameters (roller deformations, etc.), excluding the friction.
