Study on the structure preparation and compression performance of aluminum/stainless steel honeycomb composite plate
In view of the low strength of honeycomb materials and the fact that honeycomb composite panels are still mainly connected by high-strength adhesives which are prone to cracking and failure under high temperature,this paper designs composite structures with different combinations of materials and honeycomb sizes,and prepares aluminum/stain-less steel composite panels with different panel materials,honeycomb thicknesses and edge lengths by brazing process,and studies their connection effect,compression performance,energy absorption and deformation behavior.The results show that the honeycomb composite panels prepared by brazing have good connection effect;the load-bearing strength and absorbed energy of the honeycomb structure increase with the decrease of honeycomb size,and increase with the in-crease of honeycomb wall thickness and the increase of selected material strength;the aluminum alloy composite panels with excellent plasticity will undergo layer-by-layer compression collapse,and the stainless steel with less plasticity will undergo vertical deformation after a certain deformation of the specimen.
