Abstract
The present invention comprises a method for controlling the curing process of a composite material part in a curing vessel such as an autoclave. The method relies on the comparison of actual part parameter values to predicted part parameter values wherein the predicted values are obtained from computer simulations of the cure cycles using thermo-chemical, cure kinetics, resin flow and viscosity analytic models. The invention provides a methodology for the continuous selection and updating during the cure process of new optimal cure cycles from sets of cure cycles in response to actual material behavior during the curing process.
