Some developments in processing a new high-temperature resin system are described. This new class of tractable polyphenylene polymers recently became available from Hercules, Inc., and has been evaluated from the standpoint of handling, processing, and performance characteristics. A dramatic improvement was achieved in ease of fabrication as compared with conventional polymers. This was accomplished with no observable sacrifice in high-temperature performance. Despite inherent limitations in the adhesive properties of this polymer system, fiber and fabric-reinforced composites with acceptable mechanical properties were successfully fabricated. A preliminary effort to graphitize a carbon-reinforced specimen with the polyphenylene matrix indicated that the system has promise for production of mechanically sound carbon-carbon composites.
