In this research, a new technique for fabricating composite cellular cores named semi-WBK (wire-woven bulk Kagome) using yarns and straight rods has been introduced and evaluated by compression tests of three types of sandwich specimens. Following are the conclusions obtained through the design and experiments: The forces acting in in-plane struts of a Kagome-like truss subjected to compression or shear are much lower than those in out-of-plane struts. Because of the lower limit of slenderness ratio, d/c, for axial compressive strength of straight composite rods, C-FRP (carbon fibre-reinforced polymer) rods are better choice for raw materials of the out-of-plane struts to give the higher strength of semi-WBK for a given weight than G-FRP (glass FRP) rods. Semi-WBK is composed of straight out-of-plane struts and wavy in-plane struts, and all the struts are closely contact one another, which results in the exceptionally high compressive strength if the cross points are fixed sufficiently either by filling the small tetrahedral interior spaces with plain epoxy adhesive or by applying the high strength epoxy adhesive.
