In this work, the effect of activation temperature on adsorption properties ofactivated carbon fiber-reinforced phenolic resin matrix composites has been investigated.The composites were manufactured via molding process with unwoven carbon fabricsand phenolic resin. The green body molded was heated at 125℃ to cure the phenol resinand they were carbonized in an inert environment at 1, 000℃ for 2 hs. And then theywere activated by CO2-gas at 700, 800, 900 and 1, 000℃ for 2 hs, denoted as ACFC-700,ACFC-800, ACFC-900 and ACFC-1, 000 to activation temperatures. The adsorptionsurface areas and the pore structures of the samples were measured by BET-methodwith N2-gas adsorption at 77K, and the acid-base values on surfaces were determinedby titration methods. As a result, the activation temperatures were largely influenced onadsorption characteristics and surface properties of the composites.
