Numerical Modelling of the Filament Winding Proces (original) (raw)

SUMMARY A framework composed of several building blocks that allows the simulation of the filament winding process is described. The physical and thermo-chemical phenomena interacting at the layer/laminate level together with analytical description of the compaction and consolidation mechanisms were modelled and incorporated in finite element software. The filament winding process is a manufacturing technique in which a resin- impregnated continuous filament (or tape) tow is wound over a rotating mandrel. The synchronized movement of both the mandrel and the delivery head accomplishes the precise positioning of the fibres on the mandrel surface, leading to the desired geometric pattern. The ability to control of the process variables may allow improvements in the final geometry of the component, the process optimization and the strength of wound parts. In order to develop the global process model, several analytical descriptive formulations of the physical and thermo-chemical phenom...
