Abstract

The invention discloses a lightweight cross-core lattice foam sandwich panel integrating impact resistance and noise reduction and a preparation method thereof. The sandwich panel comprises: an upper panel and a lower panel arranged oppositely; the upper panel and the lower panel are made of metal materials; a plurality of skeletons placed between the upper panel and the lower panel; the skeleton is cross-shaped, with a first metal plate and a second metal plate perpendicular to each other and arranged crosswise; A plurality of skeletons are arranged in a display style between the upper panel and the lower panel; and a foam layer is filled in the gap formed between each said skeleton and the upper panel and the lower panel. The invention integrates impact resistance and noise reduction, and has the characteristics of being able to bear greater load under the same mass.

Description

technical field [0001] The invention relates to a sandwich panel and a preparation method thereof, in particular to a lightweight cross-core lattice foam sandwich panel integrating impact resistance and noise reduction and a preparation method thereof. Background technique [0002] In recent years, with the competition of space technology and the scramble for distant sea resources, it has become the key to the realization of the design scheme to greatly reduce the structural weight of the vehicle to obtain a larger payload. From the United States to the European Union, industry, academia and government have shown very strong interest in the development of new structured materials. On the one hand, with the maturity of welding technology, alloy materials such as steel and aluminum and lightweight sandwich structures of composite materials have been successfully applied in aerospace structures, and have shown unparalleled advantages and broad application prospects; On the one...
