In order to realize functional integration, a new kind of sandwich panel was made. By carrying out quasi-static shear experiments, its elastic modulus and ultimate bearing capacity with different resin immersing thickness, additional layer thickness of resin and specimen thickness were investigated. The load - displacement curves and failure models were obtained, which were compared with the traditional aluminum honeycomb sandwich panel. The experiments indicated that the integrated aluminum honeycomb and epoxy resin sandwich panel’s shearing process undergoes three phases: elasticity, yield and destruction. The specimen’s elastic modulus and ultimate bearing capacity increase with the increase of the resin thickness, additional layer thickness of resin and the specimen thickness, which greatly improve compared to the traditional sandwich structure. The composite layer and the core show good stability under shearing process, and there is no peeling-off or cracking between the composite layer and the core.
