概要

Various kinds of carbon were usedas thesurface materials in the manufacture of fire resistive composite boatds. The fire resistive boards were tested by an oxygen index method in accordance with the Japanese Industrial Standards (JIS) K 7201, and by a burn-through method. Flammability of the corbon-based boards decreased with an increase in board density.Fire endurance of the corbon-based fro bark, sawdust and rice hulls, and natural crystalline graphite. Electric resistivity of these boards increased in the order of natural crystalline graphite, synthetic graphite, natural amorphous graphite, rice hull charcoal, bark chrcoal, and sawdust charcoal. Bending strength of the carbon-based boards increased with an increase in density of boards. Reinforcing with glass whisers did not improve the bending strength of natural crystalline graphite-surfaced composite board.
