“…For cellular materials used in impact loading applications, the peak force, crush force efficiency, and energy absorption capacity per unit mass are critical indicators for impact resistance [34][35][36]. In the present study, we describe the design of hybrid structures that combine the microstructures of hollow lattices [20] and honeycombs [31] to form hollow lattice truss reinforced honeycombs (LTRHs).…”

a b s t r a c tLattice truss reinforced honeycombs (LTRHs), termed honeytubes, were developed based on a hybrid design of micro-lattice truss and square honeycomb topologies. Carbon fiber reinforced composite and polymer LTRHs were fabricated using different manufacturing approaches. Out-of-plane compression tests were performed on the LTRHs, and the properties were compared with the conventional square honeycombs. The stiffness and strength values of composite LTRHs didn't surpass those of composite square honeycombs due to the manually induced defects. On the other hand, polymeric LTRHs with perfect geometries were stiffer and stronger than the corresponding polymeric square honeycombs. A parametric study of the buckling resistance was carried out via finite element analysis, and the results indicated that hollow lattice stiffens honeycombs and increases the resistance to buckling, while the specific properties of honeytubes depend on their geometrical parameters. Moreover, the crush force efficiency and specific energy absorption were greater than those of square honeycombs and hollow lattice. This work demonstrates that hybrid designs that capitalize on micro-topologies can populate vacant regions in mechanical property charts, and provide increased energy absorption as crushing protection structures.

“…e experimental tests demonstrated that the amount of energy absorption of the honeycomb sandwiches was highly improved, reinforcing them by means of GFRP outer skins. Hussein et al [21] studied the axial crushing behaviour of aluminium honeycomb-filled square carbon fibre-reinforced plastic (CFRP) tubes. e results showed that the energy absorption (EA) of aluminium honeycomb-filled CFRP tubes increased from 20% to 36% more than the energy absorption of hollow CFRP tubes at different crushing velocities.…”

e aim of this paper was to investigate bending responses of sandwich panels with aluminium honeycomb core and carbon fibrereinforced plastic (CFRP) skins used in electric vehicle body subjected to quasistatic bending. e typical load-displacement curves, failure modes, and energy absorption are studied. e effects of fibre direction, stacking sequence, layer thickness, and loading velocity on the crashworthiness characteristics are discussed. e finite element analysis (FEA) results are compared with experimental measurements. It is observed that there are good agreements between the FEA and experimental results. Numerical simulations and experiment predict that the honeycomb sandwich panels with ±30°and ±45°fibre direction, asymmetrical stacking sequence (45°/−45°/45°/−45°), thicker panels (0.2 mm∼0.4 mm), and smaller loading velocity (5 mm/min∼30 mm/min) have better crashworthiness performance. e FEA prediction is also helpful in understanding the initiation and propagation of cracks within the honeycomb sandwich panels.
