Avimid® S is a high temperature cross linked polyimide composite with wet service capability up to 550°F (287°C) and dry service capability up to 630°F (332°C). Avimid® S has excellent thermo_x0002_oxidative stability and has been formulated to be tougher a polyimide composite than industry standard polyimide composite offering. Avimid® S was formulated to be a non-MDA, high temperature composite that would allow the use of typical safety/health procedures and personal protection equipment (PPE). It can be compression molded into low void parts to meet demanding aerospace requirements Avimid® S is solution impregnated on a variety of fibers and fabrics that result in prepregs that retain their tack and drape for up to 6 days out time at 72°F (22°C). Standard carbon fiber reinforced prepregs is with an 8-harness stain weave (fiber areal weight = 372 gsm) using Thornel®T650-35-3k HTS high temperature sized fiber. Typical applications for Avimid® S include aircraft turbine engine components such as vanes, ducts, cases and aero-structures requiring high temperature performance above 450°F (232°C).
