Abstract
In the present paper, a flax fabric reinforced epoxy composites was applied to confine concrete cylinders for enhancement of the compression performances of the cylinders. Flax fiber reinforced epoxy composites were prepared and tested on their tensile properties. It was found that the flax reinforced composites in weft or warp directions show remarkable difference in the tensile properties. Compared to the unidirectional basalt fiber reinforced epoxy system, the flax based fiber reinforced polymer (FFRP) composites exhibited relatively lower tensile strength and modulus, but higher elongation at break, and the tensile strain ∼ stress curves deviate from linearity. The compression strength and axial stain of the concrete cylinders confined with FFRPs were enhanced significantly. The FFRP confined concrete cylinders have much higher failure strain than those with basalt fiber reinforced polymer systems. The results indicated that the flax fabric can be used to confine concrete cylinders effectively.
