Barrday Composite Solutions has introduced a new fire resistant epoxy system for aircraft, rail, marine and other interior applications.
According to Barrday, the prepregs are tailored to specific manufacturing and performance benefits for laminators, moulders, and end users in a variety of OEM & aftermarket interior applications. They say EP2052 is self adhesive to aramid and aluminium honeycomb, is self extinguishing, and passes both the 12 second and 60 second vertical burn tests as listed in FAR 25.853. The prepreg is toughened and provides excellent structural properties.
Additionally, they explain that EP2052 offers a 20 minute (in hot/out hot) snap cure at temperatures of 255-275 degF (125– 35 degC) allowing for greatly improved throughput relative to standard cure systems and a Tg of 239 degF (115 degC) and has a three plus week out time.
Carl Varnerin, Vice President of Research & Development at Barrday stated, “EP2052 prepreg helps to round out our fire resistant epoxy product offerings. The prepreg provides excellent adhesion to aluminium and Nomex honeycomb cores. We believe the snap cure option would also be a substantial benefit to engineers that want to maximize the output of their equipment without additional capital expenditures and who also value the flame retardant properties.”
