Abstract
The static tensile and flexural strengths of C/A hybrid Unidirectional reinforced FRP laminates of which the volume ratio of CFRP to AFRP is 50% to 50% were measured. The effects of formation of laminates on these strengths were discussed. As the results, it was found that (1) C/A hybrid FRP has an equivalent tensile strength of the CFRP and an equivalent failure strain of the AFRP in case that the thickness of one layer is thin. (2) The flexural behaviors of C/A hybrid FRP are influenced significantly by the formation of laminates. Concretely, the knee points apear in case that the surface layer is AFRP and the formation of laminates which maximizes the flexural strength exists.
