Abstract
Rheo-kinetic behaviour of an epoxy
resin, coupled with an aliphatic polyamines hardener, used in fibre reinforced
plastics, was analysed comparing experimental data to theoretical models. Then
the modelling of technological filament winding process for thermoset matrix
composites, developed through a numerical code realized with MATLAB, is
reported. The model includes winding and curing phase decoupling the
manufacturing process into sub-models. Four sub-models are used: fibre motion,
thermal, kinetic and rheological model. Considerable differences are obtained
in process condition, using several thermal treatments. The numerical
modelling helps to detect the process conditions to optimise the filament
winding process.
