A porous material –Bi-directional Trapezoid Honeycomb (BDTH) which is different from the traditional honeycomb structure, has same energy absorption properties in the Y and Z directions was studied. The structural parameters (cell size, cell thickness) have a great influence on the compression performance. 3 kinds of cell size ( a) and 4 kinds of cell thickness ( t0) totally 7 kinds of BDTH were manufactured. The quasi-static compression test was carried out with experiment and numerical simulation, and the results were obtained. The effects of material deformation modes and energy absorption are analyzed. Next, based on Gibson-Ashby theory, the relationship between density, initial peak stress, plateau stress, densification strain and the ratio of t0/a were deduced.

“…The value of strain hardening is also show higher than unrolled. S.Y.Yang [18] performed and examined the three point bending attitude of aluminum foam having smooth face with 79.3% to 85% porosity manufactured via melt foaming process and realized that failing of sample occurred in three phases the first is elastic deformation, second is skin failure and the third is foam failure.…”

In this research the analysis and characterization of open cell aluminium foam with 20 pores per inch (ppi) of Alporas rout under mechanical loading is presented in order to provide a basic understanding with respect to pore size per unit length for the right selection in various engineering applications. For this purpose, three point bending test, tensile test, compression test, vickers hardness test and charpy impact test were performed to seek out the respective properties of each test. All samples and test procedure were performed as per ASTM standards. The scanning electron microscopy (SEM) will performed of the fractured surfaces of the specimens to investigate the failure mode. The SEM photograph shows that; some internal defects were found such as the tinny cracks some irregular shape holes in the cell wall which have been created during foaming process. The shredded cell wall is looked over which was ductile in nature and have occurred during flexural, tensile and charpy impact test. In compression; all pores are collapsed in plateau region, and some crumples and brittle tiny cracks are detected in densifications stage. Dislocation band also detected on the walls and struts of the effected sample of tensile and charpy impact test.

“…Porous aluminium is an advanced composite material and has received increasing attention in recent years because of its outstanding physical and mechanical properties, such as light specific quality and stiffness, high strength, good energy absorption, excellent shock resistance, and damp shock absorption. Depending on the pore structure, porous aluminium can be divided into two categories (closed-pore and open-pore), and both have been widely used in many fields, including construction, auto parts, electronics equipment, and aerospace [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

In this work, micron porous aluminium (Al) specimens with various porosities were successfully prepared via a cold pressing-vacuum sintering-dissolution process (SDP) with water-soluble granules as space holders. Effects of the parameters of the sintering process on microstructure, density, and hardness were investigated. Results show that SDP was used to synthesise open-cell porous aluminium with uniform holes and enabled easy control of the microstructure porosity of porous aluminium. We also found that vacuum sintering and the addition of magnesium (Mg) improved the sintered behaviours. Based on our findings, the optimised sintering parameters (temperature and time) for porous aluminium are 650°C and 270 min, respectively.
