设计和制造了用碳纤维增强的中等拉伸的可果美晶格,以粘贴片作为表皮装配成夹芯板。通过面外受压、面内受压和3点弯曲试验,对夹芯板的力学性能进行了测试,揭示了夹芯板结构的不同破坏模式。试验结果显示,碳纤维增强可果美晶格比泡沫和蜂巢具有更高的刚度和强度。研究发现,弯曲和剥离决定了夹芯结构的力学性能,表面越平越能提高夹芯板的整体力学性能。
Designed and manufactured carbon fiber-reinforced medium-stretch can be the United States lattice, with the sticking sheet as the epidermis assembled into a sandwich panel. The mechanical properties of the sandwich panel were tested by in-plane compression, in-plane compression and three-point bending test, revealing different failure modes of the sandwich panel structure. Test results show that the carbon fiber reinforced glass has better rigidity and strength than foam and honeycomb. It is found that bending and peeling determine the mechanical properties of the sandwich structure. The more flat the surface, the more the overall mechanical properties of the sandwich panel can be improved.
