Characteristic of carbon coated carbon-fiber reinforced plastics for weght lightening of electrical railway

초록

Carbon-fiber reinforced plastics (CFRPs) were used as the material for the weight lightening of the electrical railway. We proposed the carbon films as the materials for the improvement of physical properties in CFRPs. Carbon films were deposited by unbalanced magnetron sputtering method with two graphite targets. The physical and electrical properties of the carbon coated CFRPs (C/CFRP) with various thickness and RF powers were investigated. The C/CFRPs exhibited uniform surfaces at various thickness and RF powers. The hardness, elastic modulus properties of C/CFRPs were improved with increasing RF power and were slightly increased with increasing thickness. Also we confirmed the structural properties of C/CFRPs in order to investigate the relationship between the physical properties of the C/CFRPs.
