In this study, carbon textile reinforced concrete (CTRC) and engineered cementitious composites (ECC), together with steel fibers, were combined to fabricate two-layer concrete, called CTRC-ECC concrete. The dynamic compressive behavior of CTRC-ECC concrete was studied through the quasi-static compressive test and the impact test using a split Hopkinson pressure bar (SHPB). The effects of the thickness of CTRC, steel fibers, and impact face on the dynamic compressive strength, dynamic increase factor (DIF), strain at peak, and impact toughness of CTRC-ECC concrete were discussed. The results showed that as the thickness of CTRC increased, the dynamic compressive strength followed an increasing trend generally; the DIF decreased; and the strain at peak and the impact toughness increased firstly and then decreased. The addition of steel fibers to CTRC could increase the dynamic compressive strength significantly when the thickness of CTRC is less than 10 mm, improve the impact toughness slightly, but reduce the DIF significantly. In terms of the strain at peak, it firstly increased and then reduced and lastly did not change too much by steel fibers. The effect of impact face on the dynamic compressive strength, DIF, and impact toughness was not significant; however, when the CTRC face was subjected to impact load, the strain at peak could be slightly higher.

在这项研究中，将碳纤维织物增强混凝土 (CTRC) 和工程水泥基复合材料 (ECC) 与钢纤维结合起来，制造出两层混凝土，称为 CTRC-ECC 混凝土。CTRC-ECC 混凝土的动态压缩行为通过准静态压缩试验和使用分裂霍普金森压力棒 (SHPB) 的冲击试验进行研究。讨论了 CTRC、钢纤维和冲击面的厚度对 CTRC-ECC 混凝土的动态抗压强度、动态增加系数 (DIF)、峰值应变和冲击韧性的影响。结果表明，随着CTRC厚度的增加，动态抗压强度总体呈增加趋势；DIF 下降；峰值应变和冲击韧性先增大后减小。当CTRC的厚度小于10 mm时，在CTRC中加入钢纤维可以显着提高动态抗压强度，略微提高冲击韧性，但显着降低DIF。从峰值应变来看，钢纤维先增大后减小，最后变化不大。冲击面对动态抗压强度、DIF和冲击韧性的影响不显着；然而，当 CTRC 表面受到冲击载荷时，峰值应变可能会略高。冲击面对动态抗压强度、DIF和冲击韧性的影响不显着；然而，当 CTRC 表面受到冲击载荷时，峰值应变可能会略高。冲击面对动态抗压强度、DIF和冲击韧性的影响不显着；然而，当 CTRC 表面受到冲击载荷时，峰值应变可能会略高。
