Abstract: The quasi-static mechanical properties and dynamic compression behavior of polyethylene fiber (PE) and basalt fiber (BF) hybrid fiber rubberized Engineered Cementitious Composites (PE/BF-CR-ECC) were systematically studied, and the influence mechanism of high rubber powder content on the dynamic response of the material was revealed.When the rubber content is 20vol.%, PE/BF-CR-ECC has excellent static tensile strain (5.16%) and static tensile stress (5.08 MPa). In the split Hopkinson bar (Split Hopkinson bar, SHPB) test, a bullet at 3.7 m/s, 4.5 m/s, 5.2 m/s velocity was used to impact the specimen and remained intact under 5.2 m/s bullet impact. As the rubber content increased from 0 to 40vol.%, the dynamic embrittlement trend of the material weakened, but the strain rate sensitivity of the dynamic compressive strength increased, and the dynamic intensity factor (Dynamic intensity factor, DIF) was up to 2.16. This is because the incorporation of rubber reduces the pore size, increases the specific surface area, refines the pore structure and intensifies the free water effect. In addition, the addition of rubber significantly improved the energy dissipation capacity of the material at high strain rate, and the energy dissipation efficiency at 160 s⁻¹ strain rate was more than 4 times that of the rubber-free group. Through comprehensive evaluation, PE/BF-CR-ECC with 20vol.% rubber showed the best impact resistance.
