초록
The carbon fiber reinforced plastics, one of unidirectional fiber-reinforced composite materials, are widely used in various field including space and aviation industries, sports and leisure industries and general structural members and parts as have high strength in comparison with the weight, elasticity coefficient, high fatigue strength and lower thermal transformation. This paper present analytical behavior of CFRP pipe reinforced rib under the external force. From the results, the maximum compressive stress occurs at the upper flange of CFRP pipe and tensile stress occurs middle flange of the CFRP pipe. The stress of rib CFRP pipe by increasing effective cross-sectional area was reduced by approximately 35%.
