Abstract
An integrated model is developed for the Resin Transfer Molding (RTM) process which uses a constraint based non-linear optimization technique to calculate process set point values that correspond to minimum cycle time. The effects of process variables on temperature distribution which is directly related to part warpage and shrinkage are identified and incorporated as constraints into the model. The objective function consists of two mathematical models which represent the flow and cure stages of RTM. To illustrate the methodology, the study of a thin walled fiber reinforced plaque is presented. The results provide optimal molding parameters which produce higher quality parts in less time than traditional molding practices.
