In order to obtain a lightweight, high-strength, and customizable cellular structure meet the needs of modern production life, mechanical properties four thickness gradient honeycomb structures were studied. this paper, types specimens with same porosity different Poisson's ratios designed manufactured by using SLA 3D-printing technology, including honeycomb, square quasi-square re-entrant structures. Based on plane compression failure mode analysis these specimens, is applied structure,...
To obtain a lightweight and high-strength wood sandwich structure, wooden lattice cell element was designed in combination with pyramid-type structure. After inserting glue to prepare the unit, influence of panel thickness core diameter on unit force analyzed compared under condition flat pressure. Under pressure, specific strength higher than that composition material, may be regarded as structure high strength. Theoretical predictions, simulation analysis, experimental tests demonstrated...
In order to obtain a lightweight, high strength, and large design space wooden sandwich structure meet the needs of modern buildings, mechanical properties fabricated 2D pyramid lattice were studied. this paper, compressive specimens with different arrangement Lattice Sandwich unit cells are The upper lower panels core materials made into single cell by inserting glue, prefabricated truss is prepared mortise tenon splicing method. results show that in specimen has significant effect on...
In order to reduce the weight of panels used in buildings and minimize use wood, it is great practical significance study mechanical properties wood-based sandwich structures for adaptation modern wood-structured buildings. this paper, a pyramid structure specimen with large interconnection space was designed prepared first. Based on results flat compression, strengthen core layer structure, an interlocking grid can be used. The two kinds specimens, including bearing capacity, compressive...
