Abstract
Two sheets of steel hollow sphere sheet (TEC SHEET) are laminated and its mechanical property is investigated by means of stab proof test. The construction is sandwiched by a pair of pure aluminum plates with two kinds of bonding methods. Three point bending test and compression test are conducted for the construction. As the results, stab proof strength is advanced more than that of a single layer sheet. In the bending test, bending load increases with increase of the layer in the sandwich construction. Bending mechanism is investigated and the influence of bonding method on breakage condition of the sandwiches. Compression test for the sandwich construction and foam metal filling construction is conducted and the difference of the energy consumption behavior is investigated.
