Abstract The Resin Transfer Molding (RTM) method has been used recently to fabricate several composite components for aircraft gas turbine engines. These components tend to be smaller than typical airframe components, have more complex shapes, require closer dimensional control and are produced in higher quantities. The AdvRTM process was selected to mold the components as a result of trade studies conducted which showed that the process could accommodate design features that resulted in a more competitive product than autoclave or press molding. In several instances, AdvRTM fabrication technology resulted in cost savings by integrating several components into a single more complex component. This paper discusses the modern AdvRTM process from the perspective of component design features that are now achievable. Also included is a discussion of demonstrated as-molded dimensional tolerances, AdvRTM vs. autoclave molded material strength, quality, lead time issues and the emerging rapid prototyping tech nology.
