Abstract
Polyimide (PMR-15)/fiber composites are important structural component s in many high temperature applications requiring high performance lig htweight materials. Most composites are fabricated from ''prepregs,'' but resin transfer molding (RTM) is an alternative route to the format ion of a resin-saturated preform, further processing of which yields t he final part. A simple model is proposed for the RTM of ''thin'' comp osite parts. Numerical solution of the model is accomplished through i ntegration of the equations formulated using the finite element method . This approach accounts for the changing shape of the flow front duri ng RTM. The resulting computational schemes are numerically stable and efficient.
