摘要
•New aramid weft-knitted spacer fabric reinforced cementitious composites were developed.•The spacer yarn density and surface yarn density on mechanical performance of composites were investigated via the quasi-static bending test and low-velocity impact test.•Aramid weft-knitted spacer fabric reinforced cementitious composites show excellent structural integrity during ductile deformation.•Asymmetrical structure of fabric can contribute to better bearing capacity of composites by altering stress transfer.
