Summary: By incorporating aramid fiber and carbon fiber into concrete in a hybrid manner, this study aimed to enhance the static and impact mechanical properties of the material. The test results showed that the presence of a coupling agent on carbon fibers affected the mechanical strength of the reinforced concrete, with a 50-50% mix proportion of Kevlar/carbon fiber significantly improving compressive, flexural, and splitting tensile strengths. Additionally, the hybrid fiber-reinforced concrete exhibited better performance in mechanical strength and impact resistance compared to concrete with only Kevlar or carbon fibers.
