PRF Composite Materials RP549
- Chemical Family
- Epoxy & Epoxy Derivatives
PRF Composite Materials RP549 is a highly toughened modified epoxy prepreg that has been specially formulated for the production of components requiring high mechanical properties and good impact resistance, particularly those exposed to elevated temperatures. This new system has an >200°C Tg following the 180°C cure cycle, and provides excellent mechanical properties in tensile, ILS and flexural strength. RP549 is now in manufacture on a range of our high quality woven fabrics.
