Outline of Final Research Achievements

Freedom of CFRP material design as a laminate composite is wide, and deformation and strength characteristics of structural members change widely according to its laminate structure. Therefore, in order to establish the design method of a CFRP structural member, it is necessary to understand loading effects and damage states of a structural member. Through the integrated approach of material and structure with material element experiment, structural member experiment, image analysis, composite theory, and finite element analysis, this research clarified the mechanisms of deformation and load bearing behavior and improved the deformation and load bearing performance of a CFRP structural member.
