Process simulation of wet filament winding and curing of thick walled cylinders

• The present work concerns the development of a process model for wet filament winding of thick walled cylinders with a thermoset resin. The model calculates the fiber content, curing degree, temperature, stresses and strains throughout the process. The material laminae data are continuously updated by use of a micro-mechanical model. A reaction kinetics model for the used epoxy resin has been established. Plane compaction data on glassfiber rovings, for different winding angles, have been measured. A software supplied by Stanford University has been used as a basis for the numerical simulation. It has been extensively modified. Measurements have been performed on a 4-axis, numerically controlled winding machine. The experimental results are in good agreement with simulations.
