Thermal Residual Stress Simulation in Thermoplastic Filament Winding Process

Thermal Residual Stress Simulation in Thermoplastic Filament Winding Process The present paper describes an advanced model to simulate the residual stresses of reinforced filament wound thermoplastic composites. The nonlinear characteristics of the problem are reduced by decoupling some of the phenomena and the associated dependent variables into submodels. Four submodels are used here: fiber motion, thermal, kinetic and rheological as well as a stress-strain submodel. The models were tested on a selected GF/PP sample chosen from a sensitivity study which is presented also. The effect of individual process parameters on the residual stresses in filament wound parts is rated by a sensitivity study. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Thermoplastic Composite Materials SAGE

Thermal Residual Stress Simulation in Thermoplastic Filament Winding Process

Abstract

The present paper describes an advanced model to simulate the residual stresses of reinforced filament wound thermoplastic composites. The nonlinear characteristics of the problem are reduced by decoupling some of the phenomena and the associated dependent variables into submodels. Four submodels are used here: fiber motion, thermal, kinetic and rheological as well as a stress-strain submodel. The models were tested on a selected GF/PP sample chosen from a sensitivity study which is presented also. The effect of individual process parameters on the residual stresses in filament wound parts is rated by a sensitivity study.
