“…van Vuure et al [5] predicted compression and shear modulus of the core theoretically based on a finiteelement preprocessing program. Many other studies [6][7][8][9][10][11] also studied static compressive, shear and bending behavior of 3D integrated woven spacer composites with different core heights and showed the face sheets have a significant impact. For dynamic loading, Vaidya et al [12,13] studied low-velocity impact of a series of functionality sandwich composites, and proved that wax filling, wire routing and polycarbonate-sheet facing can delay and suppress the damage of hollow core.…”

3D integrated woven spacer composites with thickened face sheets are fabricated successfully. Static compression and impact behavior are analyzed to evaluate the effect of thickened face sheets. The results show that thickened face sheet is an important influence parameter, warp compression and impact properties have been improved significantly than those of composite without thickened face sheets. Moreover, the damage and failure mechanism is significantly different. The main failure mode under flat compression is an abrupt rigid breakage of core fiber bundles. However, the thickened face sheets reduce the shear stress that transfer to core fibers. For warp compression, there is no face sheets fracture or dislocation, the local shear fracture occurs on the thickened face sheets. In regard to low-velocity impact, the strength of thickened face sheets dominates the failure, the damage is mainly manifested as the penetration of the top and bottom face sheets, matrix cracking, interface debonding, micro-buckling, as well as tearing and breakage of core fibers.

“…Zhou et al [10] proved that the tensile and double lap shear properties of the hollow integrated core sandwich composites are better than those of traditional honeycomb sandwich composite materials. Fan et al [11] focused on the multi-layered panels by stacking thin monolayer panels, and the quasi-static compression experiments showed that the energy absorption of the multi-layered panel has exceeded far more than that of the monolayer panel of the same thickness.…”

The charpy impact experiments on the 3D integrated woven spacer composites with six types of core heights are performed at room and liquid nitrogen temperatures (as low as -196 o C). Macro-fracture morphology and SEM micrographs are examined to understand the deformation and failure mechanism. The results show that the impact energy increase with the increase of the core height at both room and liquid nitrogen temperatures. Meanwhile, the impact properties at liquid nitrogen temperature have been improved significantly than that at room temperature. Moreover, at room temperature, the penetration fracture of the face sheets, the tearing and pulling out of the core fibers as well as the cracking of the matrix is the main damage and failure patterns. However, at liquid nitrogen temperature, the matrix crushing dominates the failure. Less fibers fracture and brittle fracture feature becomes more obvious. In addition, with the increase of the core heights, the damage of composites has been reduced significantly at room and liquid nitrogen temperatures.

“…3D woven spacer composites have better compression and shear features than conventional counterparts [20,21]. Furthermore, compression and low-velocity impact study were carried out by Vaidya et al, where it was found that with the increment of thickness and the presence of core piles in 3D woven spacer composites, the peak load and fracture under compression and low-velocity impact reduced respectively [22,23]. Belingardi et al investigated that the sandwich structures which incorporate resin net walls in the foam core can be sustained in a remarkable increment of the dynamic impact response [24,25].…”

Three-dimensional (3D) woven spacer composites have the advantage of being lightweight and strong for use in various segments of structural engineering and automobiles due to their superior mechanical properties than conventional counterparts. In this investigation, the influence of different cell geometries of 3D woven spacer fabrics, namely rectangular, triangular and trapezoidal with woven cross-links, upon their mechanical behaviors, especially compression energy, was studied through FEM (finite element method). Cell geometries were changed into different heights and widths and evaluated through simulation and experiments. Simulation of the structure was carried out by the Abaqus platform, and validation of the results was done for the rectangular structure. It was found that compression energy increases with an increment in width, while initially, it shows the tendency to increase and subsequently decrease with an increment in height for the rectangular structure. Compression energy increases with an increase in the angle of the triangular structure; however, it shows the opposite trend in the case of the trapezoidal structure. The outcome of the result shows good agreement between simulation and experimentation values of more than 94% accuracy.
