The Properties of Oxidated Carbon Fibers Reinforced Cement


Article Preview

Carbon fiber (CF)is the most important reinforcement in advanced composites.Carbon fiber-reinforce cement(CFRC)possess all right mechanical properties.Carbon fiber-reinforce cement(CFRC)was produced after Carbon fibers (T700) were slightly oxidized by the method of oxidation treatment at 773K in air for a short time. The result indicates that the density of CFRC reduces, porosity enhances, the bending strength and the compressive strength enhance when carbon fibers increases,by detecting the pre-and post-treatment physical and mechanical properties of CFRC, observing the microstructure of the fracture of the Side Bend Test samples. SEM morphology shows that the fracture of carbon fibers without oxidation is pull-out failure mainly while these with oxidation is pull- cut failure mainly. In a word,Carbon fibers with slight oxidation can improve the combine state of the interface between the fibers and the matrix, and accordingly improve the mechanical properties of the CFRC.
