AVIMID N is a high temperature, post curable, Tg 775°F (413°C), polyimide composite with wet service capability up to 630°F (332°C) and dry service capability of 700°F (370°C). AVIMID N has the industry’s best thermal oxidative resistance of all organic matrices and is the preferred product when high temperature durability is needed. It is a very tough composite system and has favorable dielectric properties making it well suited for missile and turbine engine applications.

AVIMID N 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 or alternatively processed in a vacuum bag autoclave process to meet more flexible requirements usually seen in non-aerospace applications.

AVIMID N 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 at 70°F (21°C). Tack can be regenerated or enhanced in a limited way by spraying the prepreg with ethanol. The prepregs have a shelf life warranty of 12 months from the date of manufacture when stored at 0°F.
