U.S. Naval Research Laboratory Chemistry Division scientists
have developed a second generation, cost-effective polyetheretherketone
(PEEK)-like phthalonitrile-resin demonstrating superior high temperature and
flammability properties for use in numerous marine, aerospace, and domestic
applications.
The resin can be used to make composite components by
established industrial methods such as resin transfer molding (RTM), resin
infusion molding (RIM), filament winding, prepreg consolidation, and
potentially by automated composite manufacturing techniques such as automated
tape laying and automated fiber placement.
