Review of Carbon Fiber Composite grid with Manufacturing and Design Concepts for Seismic Resistance

초록

To fabricate the hybrid grid for seismic performance reinforcement, carbon fiber composite yarn with appropriate stiffness and ductility was fabricated and the optimum structure of the grid was designed and tested. Composite fiber of carbon fiber/aramid fiber/high strength polyester fiber was fabricated by double covering process, and the strength was increased by about 0.5% compared with carbon fiber which is matrix material. The TPU(thermoplastic polyurethane) extrusion coating method was more suitable for the carbon fiber composite yarn than urethane impregnation for the coating process. Creep properties of hybrid grid fabric of carbon fiber composite yarn during a simulated seismic event were evaluated using the SIM test method.
