Abstract

In this study, a carbon fiber composite yarn with the desired stiffness and ductility was fabricated for use in hybrid grid fabrics for seismic reinforcement, and the optimum structures of the grid fabrics were evaluated. Carbon fiber composite yarn was prepared by a double-covering process with carbon fiber/aramid fiber/high-strength PET fiber. It was confirmed that the strength of the carbon fiber composite yarn was greatly increased compared to that of carbon fiber, and the elongation increased by about 0.5%. The TPU (thermoplastic polyurethane) extrusion coating method was more suitable for the carbon fiber composite yarn than urethane impregnation for the coating process. Meanwhile, in the evaluation of yarn fineness and grid structure, thick fibers had greater strengths. When comparing the strength and elongation, the bi-directional grid showed no advantages over the unidirectional grid.
