Invincible. The next generation of thermoset matrix resins CALIDUR® polyetheramide resins CALIDUR® is a new class of thermoset matrix resins that combines the high flame retardancy of phenolic resins with the mechanical properties of high TG epoxy resins. Benefits CALIDUR® provides much greater design flexibility for carbon fiber and glass fiber composite structures in aircraft and other transportation interior applications. Properties • Intrinsic FST performance • High TG • Excellent surface quality Processing • Rapid processing and curing • Formaldehyde-free • Thermoformable • Storage-stable at 8°C CALIDUR® is supplied as a resin solution or in powder form. Prepregs with various fiber reinforcements are available via our partner c-m-p GmbH. Prepreg production Drying Dry fabric Resin solution Impregnated fabric Dry prepreg Parts production Autoclave Compression molding press Our Partner 2 In addition to enabling short production cycles, CALIDUR® does not require binders while providing greater flexibility across a wide range of curing temperatures. With a very low shrinkage of < 0.5 % and superior characteristics compared to stateof-the-art phenolic compounds, CALIDUR® also demonstrates very good mechanical properties. Prepreg characteristics Tackiness No tack Storage stability Stable for at least 6 months at 8°C Curing cycle Wide range of curing conditions possible TG after curing (30 mins at 150°C)* DSC 152°C TG after curing (10 mins at 180°C) DSC 163°C * TG after curing (45 mins at 180°C) * * DSC 187°C 1 layer glass fiber prepreg (300gsm, E-Glass HexForce 07781, 8H satin) 3 CALIDUR® meets both Airbus FST (ABD0031) and FAA requirements, and is competitive with phenolic resin.
