説明

<p>Carbon fiber is almost impossible to be burned out by even high temperature burnt gas because of extremely high melting point of carbon fiber and a low oxygen concentration in burnt gases. In this study, first, oxygen nozzle of 10 mm x 30 mm exit size, which equipped fuel (propane) pipe of inner diameter of 0.8 mm for a pilot ignition flame, has been introduced to observe the in-oxygen-combustion behaiviors of test pieces of (i) CFRP slender plate (2 mm wide and 1 mm thickness), (ii)slender plate of CFRP-P (Plastic removed CFRP), "G"FCRs("Graphite" Fine Cylindrical Rod) of diameters of 0.38 mm, 0.55 mm and 0.72 mm. In order to obtain the fundamental data for analysis of CFRP combustion processes, the flow pattern of combustion gas around "G"FCR and the light emission of "G"FCR surface were also observed. SEM observations on tips of "G"FCR and CFRP revealed that the burnt CFRP tip was extreamely sharpened by the oxygen combustion to have a nanometer-order curvature radius.</p>
