HYBRID FIBER COMPOSITE AND REINFORCING CONCRETE STRUCTURE USING HYBRID FIBER COMPOSITE

摘要

A hybrid fiber reinforcement and a reinforcing method of a concrete structure using the same are provided to prevent sudden brittleness and to increase ductility by placing first reinforcing parts made of a carbon fiber or an aramid fiber, and a glass fiber, and second reinforcing parts made of a glass fiber. First reinforcing parts(311) having 1:5~10 of a volume ratio between a carbon fiber(311a) or an aramid fiber(311c) and a glass fiber(311b) are woven along the width direction in series. Second reinforcing parts(112), which are made of a glass fiber, are woven with a perpendicular direction to the first reinforcing parts in series to form the hybrid fiber reinforcement with a sheet shape. Third reinforcing parts(430) and fourth reinforcing parts(440) are arranged to + 45° of the first reinforcing part and to - 45° of the second reinforcing part respectively.
