[0002] Foamed aluminum is made by adding additives to pure aluminum or aluminum alloy and undergoing a foaming process. It also has the characteristics of metal and air bubbles. It has low density, high impact absorption capacity, high temperature resistance, strong fire resistance, corrosion resistance, and sound insulation. Noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, high forming precision, surface coating, aluminum foam has excellent physical properties, chemical properties and mechanical properties and Recyclability, these excellent properties of foamed aluminum make it have broad application prospects in today's material field, and it is a promising engineering material, especially in the transportation industry, aerospace industry and building structure industry. Aluminum is widely used and has various uses, so it needs to be deformed during processing and use. Therefore, before deformation treatment, it is necessary to perform tensile testing on foamed aluminum. The foamed aluminum tensile test fixture is mainly used in the experiment of testing the tensile strength of foamed aluminum. , but the current detection fixture does not consider the characteristics of foamed aluminum itself. The material is porous and the relative density is small. The detection device used in the detection process is that the upper and lower clamps clamp the two ends of the foamed aluminum composite material sample to be tested and stretch it. Strength test, but when the two ends are subjected to tensile force during the experiment, the tested aluminum foam composite material will automatically fall off due to the different properties of two or more materials, or cause structural damage to the foam aluminum composite material, affecting Experiment, so the current tensile test fixture can not meet the tensile test of foamed aluminum
