High Temperature Polyimides for Resin Transfer Molding Process

Triton Systems, Inc. proposes to develop novel low melt flow viscosity, environmentally friendly high temperature polyimide resin that can address the need for low cost, lightweight, complex geometry composite manufacturing. Triton has teamed with composite manufacturer and end users to assist in evaluation of its new RTM/VARTM high temperature polyimides. The proposed program will develop resins with melt flow viscosity lower than 10 poise at greater than 280?C processing temperature. High temperature RTM/VARTM resins would allow ?out-of-autoclave? manufacturing, which reduces manufacturing cost and allow for large, complex shape designs. The new high temperature resin will be applicable to propulsion systems such as aircraft gas turbines, rocket and turbine engines, and auxiliary power in aircraft and space vehicles.
