Abstract: Concrete reinforced by textile composite materials has long been a focus of substantial interest in the engineering applications. In this paper, the compression performance of concrete cylinders confined by carbon fibers, glass fibers, and carbon–glass hybrid triaxial woven fabric composites under three different eccentricities were investigated. Moreover, the digital image correlation analysis method was introduced to observe the compression process and failure modes of reinforced concrete cylinders. Meanwhile, the strain process of yarns during the failure was also analyzed. The result showed that all of triaxial woven fabric composites can increase the strength of concrete cylinders, while the strength decreased with the increase of eccentricity and the mechanical performance converged gradually. In addition, using triaxial woven fabric composites made of glass fibers can promote the ductility of concrete cylinders. It also indicated that employing carbon–glass hybrid triaxial woven fabric composites can not only have the advantages of increasing the strength and ductility of concrete cylinders, and low cost, but also effectively reduces the eccentric sensitivity.
