Abstract : The present invention pertains generally to high-temperature resins and their precursors and in particular to perfluorinated aliphatic phenoxy bisorthodinitriles and the cyano-addition resins therefrom. Fiber-reinforced composite materials which comprise carbon or graphite fibers dispersed in a resin are replacing metal in many structural applications because of weight savings, cost effectiveness, better properties and a greater range of properties. The greater range of properties of composites over metals arises because the property variations of polymers are greater than that of alloys. Another advantage of composites over metals is the new design concepts made possible by the improved properties.
