Navy Licenses New Resin for Commercial Use

The U.S. Naval Research Laboratory (NRL) has announced that it will be licensing a new NRL developed PEEK-like phthalonitrile (PN) resin system. Key points of the new PN resin include:

  • Superior flame resistance
  • High temperature – remains strong up to 500 deg. C
  • Low water absorption
  • indefinite shelf life without refrigeration
  • easily used out of autoclave

This resin is suitable for the construction of composite components for aerospace, marine, structural, wind energy, robotic, and numerous other applications by established manufacturing techniques including RTM, RIM, filament winding, and prepreg.
