RTM-Processable Resins Containing Thermosetting Plasticizers

A number of matrix resins that contain thermosetting plasticizers have been developed for use in the resin-transfer molding (RTM) of composite-material (fiber/matrix) parts. These resins and composites are candidates for use in manufacturing lightweight components of aircraft engines and other structures that must withstand temperatures up to and perhaps somewhat above 300 °C.
