摘要

摘要: 利用ϕ50 mm分离式霍普金森压杆（SHPB）装置对玄武岩纤维增强水泥基复合材料（BFRCC）进行冲击压缩试验，通过对3种不同纤维掺量的BFRCC试件在不同应变率下的动态压缩力学性能、吸能性能和韧度指数进行试验研究，结果表明：不同纤维掺量BFRCC的动态抗压强度、破碎状态、韧度系数等均具有明显的应变率效应；相近应变率条件下随着纤维掺量的增加，BFRCC试件的能量吸收呈现上升趋势；随纤维掺量的增加，BFRCC的韧度系数上升速率增大。

Abstract: In order to study the dynamic compression mechanical properties of basalt fiber reinforced cementitious composites (BFRCC), different strain rates were applied to three different fiber content BFRCC specimens by using ϕ 50 mm Split Hopkinson Pressure Bar (SHPB) device. Under the dynamic impact compression test, the energy absorption capacity and toughness index of each group of specimens were calculated by the principle of energy conservation. The results showed that the dynamic compressive strength, fracture state and toughness coefficient of cement-based composites with different fiber contents had obvious strain rate effects; with the increase of fiber content,under similar strain rate conditions, the absorbed energy of the specimen showed an upward trend; the toughness coefficient increased with the increase of fiber content.
