High-Tg Thermosetting Polyimide

A thermosetting polyimide called "DMBZ-15" has been developed for use as a matrix material in relatively inexpensive matrix/fiber composite materials. The glass-transition temperature (Tg) of DMBZ-15 is 414°C. In contrast, the industry standard polyimide for such composites (developed in 1971 at Lewis Research center and known as "PMR-15") has a Tg of 348 °C. Because of its higher Tg, DMBZ-15 is better suited for high-temperature use in automotive and aerospace applications.
