Abstract
In the Japan Reinforced Plastics Society, for the purpose of development of Phenolic Composite Exterior Wall Methods, the fire resistance of Phenolic Composite Panel was examined by large-sized specimens. Case 1 : the influence of density of thermal insulating foams upon the fire resistance. Case 2 : the influence of the interval of FRP panel rib upon the fire resistance. Case 3 : the influence of fire direction ( outdoor or indoor ) upon the fire resistance.
