Carbonization of Phyllostachys pubescens Mazel ex Houxeau de Lehaile(PP)at several stages was done and the burned-charcoal(BC)obtained was used in this study. The effects of the carbonization temperature of PP on the charcoal yield, amount of charcoal clement, oxidation start temperature and specific surface area were discussed. Thermosetting charcoal spheres(CPS)were made by BC and phenol-formaldehyde resin(PF)and they were used in the manufacture of fire resistive and electromagnetic shield composites. The carbonization temperature of BC relative to fire resistivity, electroresistivity and electromagnetic shielding properties of composites were also discussed. The fire resistivity of the carbon composites was tested by a burn-through method and by the oxygen index method in accordance with the Japanese Industrial Standard(JIS)K 7201. Electroresistivity was tested by JIS K 6911 and electromagnetic shielding property by a DUAL chamber method in accordance with ASTM ES 7-83. The fire resistivity and electromagnetic shielding property of the composites were improved by increasing carbonization temperature, while electroresistivity became low.
