Abstract
The addition polymerization resin systems phthalonitrile, diethynyldiphenyl methane, phenolic triazine, and polyphosphazene are disclosed as the matrix constituent in fiber-reinforced ablative nozzle components. Various types of fibers such as carbon fibers, preferably rayon and polyacrylonitrile (PAN) based, graphite fibers, glass fibers, ceramic fibers, and silica fibers may be used in the nozzle composite materials. Fillers, such as carbon black, ground silica, ground petroleum coke, and microballoons, may also be included in the ablative nozzle components. The fiber-reinforced ablative nozzle components include from about 20% to about 40% resin, by weight, from about 45% to about 60% fiber, by weight, and when present, from about 3% to about 15% filler, by weight.
