Low velocity impact responses of hollow core sandwich laminate and interply hybrid laminate

Fabrication, properties and failure of 3D integrated woven spacer composites with thickened face sheets

“…Li et al [5] studied the three-point bending properties of 3D integrated woven spacer composites with different core heights and showed that the face sheets have significant impact on bending properties. Many other studies [6][7][8][9][10][11][12][13][14] also showed that the face sheets of the integrated woven spacer composite carried most of the load that applied, even determined its mechanical properties. However, the face sheet of conventional 3D integral hollow core sandwich composite is very thin and weak in sustaining loading, which greatly restricts the engineering applications.…”

Low-velocity impact and static behaviors of high-resilience thermal-bonding inter/intra-ply hybrid composites

“…The static and dynamic puncture resistances of inter-ply [12,13] and intra-ply hybrid structural compound fabrics [14,15] have been investigated separately, but studies on the correlation properties of inter/intra-ply hybrid composites are infrequent. Non-penetrating impact behavior, such as the cushioning of honeycomb [16] and rigid composites [2,5,[17][18][19], has been studied by previous researchers, but rarely in hybrid composites.…”

Static and dynamic mechanical behavior of 3D integrated woven spacer composites with thickened face sheets

“…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. Shyr et al [14] investigated the low velocity impact responses and damage characteristics of a hybrid structure which made by laying a sandwich structure into a multi-axial warp knit blankets. Hosur et al [15] studied the high strain rate response ranging from 742/s to 1546/s for foam filled 3D integrated core sandwich laminates with 17.6 mm core height using a split Hopkinson pressure bar setup.…”
