Abstract : Results of the tests on foam silicon carbide are reported. This material has been manufactured in various densities, ranging from 10 lbs/cu ft to 38 lbs/cu ft. Specimens of 10 lbs/cu ft density and 38 lbs/cu ft density were tested. Due to the weakness of the 10 lbs/cu ft material, testing was limited on the foam of this density. The tests were modulus of rupture at room temperatureAND AT 2500 F, thermal exposure at temperatures up to 3000 F, thermal conductivity and thermal expansion at temperatures up to 1800 F. To obtain some indication of the thermal shock resistanc one panel of the 38 lbs/cu ft foam was heated to 3000 F and plunged into cold water. Due to the small amount of material received, the number of test points was limited. If the test data presented show favorable properties for any particular applic ation, additional testing should be conducted to verify the results. (Author)
