PB1000 Modified Benzoxazine Resin Next Generation Prepreg for Aircraft Interiors Fibre reinforced thermosetting preimpregnated material for aircraft interior parts No free phenol and formaldehyde, fulfils AP2091 Non-volatile curing, 140°C / 45min, 160°C / 15min Outstanding surface quality Excellent FST and Heat Release behaviour, fulfils ABD0031 Improved mechanical properties Long shelf and shop life Introduction Gurit is proud to present its next generation of aircraft interior prepregs based on PB1000. PB1000 is a modified benzoxazine resin that is without free formaldehyde and phenol and satisfies the most recent environmental standards like AIRBUS AP2091. It features a non-volatile, rapid cure, generating a perfect void and porous free surface, through which time and cost consuming rework, is eliminated. Gurit’s novel PB1000 fully complies with demanding international JAR/FAR fire protection regulations regarding flammability, smoke, toxicity (FST) and heat release. Due to its excellent mechanical performance, PB1000 is perfectly suited to fulfil present and forthcoming stress criteria for interior design. Meeting increasing demands on cost efficiency in aircraft interior manufacturing, PB1000 is also designed for commonly used fast hot-in / hot-out curing processes. This unique material performance combined with a competitive cost price level makes PB1000 an advantageous choice for aircraft interior applications and is clearly capable to replace phenolic systems.
