Study on structure of magnesite samdwich

This paper discussed a new structure of compound samdwich which is composed of foam with lower density and columned magnesite. By virtue of the compound samdwich with the higher ability in the resistance of shearing stress and crushing stress, the new structure of compound samdwich has higher performance in the resistance of bend. Because the structure and the board are simultaneously formed without interface, the question that the interface can bring up the lower performance of the sample will be completely solved. The magnesite samdwich board, if the new structure is applied, will make great progress in structure, process, performance, fixing.
