RTM and RI Processible Tailorable Polyimide Resin Systems and Composite Articles Formed Therefrom |
摘要 |
Tailorable polyimide resin systems suitable for processing by resin transfer molding (RTM) and resin infusion (RI) methods. An exemplary resin system includes first and second prepolymer components present in respective amounts to provide the desired processibility. The cured polyimide system exhibits high glass transition temperature and other properties required for gas turbine engine applications. The first and second prepolymer components independently comprise a monomeric mixture or a reaction product of a diamine component, a dianhydride component, and an end group component.
