AVIMID RB is a high temperature, Tg 644°F/340°C, thermoset polyimide resin with wet service capability to more than 530°F/277°C wet and 600°F/316°C dry service capability. AVIMID RB has excellent thermal-oxidative stability and resistance to aircraft fluids.

It was formulated for prepreg autoclave vacuum bag processing, but it can be successfully compression molded both as a prepreg and in dry forms as neat resin or chopped-fiber molding compound. Unidirectional tape and woven prepreg of AVIMID RB will retain their tack and drape for 14 days at 70°F/21°C.

Standard autoclave or compression molding processes, to a final temperature of 680°F/360°C will result in full Tg development/cure, with no need for post-cure treatment. AVIMID RB can be solution impregnated on a variety of fibers and fabrics.
