Abstract

1,156,041. Carbon bodies using polyaromatic compounds; silicon carbide. NORTH AMERICAN AVIATION Inc. 15 Sept., 1966 [1 Oct., 1965], No. 41241/66. Heading C1A. [Also in Division C5] A polyaromatic compound defined as a polymer of an aromatic monomer in which the monomer units are joined together by direct links between the carbon atoms of the aromatic rings of the monomer units is compacted and then pyrolized. Polytoluylene, polynaphthylene, and polyphenylene are given as examples of polyaromatic compounds. Preferably a pressure greater than 1000 p.s.i. is used during the compaction, and a temperature of 650‹ to 2500‹ C. in the pyrolysis, the residence time of the compact in the furnace being generally 1 hour. In the examples, an argon atmosphere is used in the furnace. The product is said to be similar to graphite, but is harder and stronger. Fillers may be mixed with the polyaromatic material before pressing. These fillers may be graphite, boron or for example, metallic borides, carbides and nitrides which latter oxidize during pyrolysis to give on the resulting body an oxidation-resistant coating. Silicon which will react to form silicon carbide during pyrolysis may be mixed with the polymer. The mixture of polymer and filler may be moulded into articles, e.g. pipes and bricks at the compression stage.
