シラスバルーン・炭素複合材の製造とその物性

抄録

Silas balloon-carbon composite material was prepared from silas balloon and pitch binder mixture, where the pitches used were coal-tar pitches and asphalt pitches. The best conditions for production of this composite material were determined from the measurement of bulk density and compressive strength of silas balloon-carbon composite material prepared under various condition. The heat-resistance and the resistivity against chemical reagents of this composite material were measured, and the microstructure of this composite material was observed by a optical microscope.
From these results, the properties of silas balloon-carbon composite material obtained are following, that is, bulk density is 0.8-0.85g/cm³, compressive strength is 290-300kg/cm², bending strength is 140-150kg/cm², heat-resistance is 400°-500°C in the atmosphere of oxidizing gas and 1150°C in the atmosphere of non-oxidizing gas.
