Abstract
3D bi-axial spacer weft-knitted fabric combines the advantages of bi-axial reinforced structures with that of spacer structures. The connection of two bi-axial layers by spacer yarns enhances its mechanical performance against delamination. In order to assess this performance, delamination test was carried out. Moreover, Hopkinson bar impact test was conducted to study the dynamic responses of the composite under the high strain rate. The results indicated that the anti-delamination properties of the fabric are closely related to connecting yarn densities, and dynamic responses of the reinforced composite are greatly improved by the connecting yarns. Such researches could also be considered as a reference in the design of other 3D knitted composite structures.
