Production of Aluminum Glass Fiber Reinforced Foam Synthesized by Space-Holder Technique

Abstract

Aluminum and its reinforced type with glass fiber composite foams were produced by powder sintering process using spherical carbamide particles as a space holder. The foams with 40-60 vol.% porosity fractions were successfully produced after water leaching and sintering methods. Compression test was performed on both of the foam samples for comparing the compressive properties and energy absorption behavior of them. The composite foam samples with glass fiber reinforcement showed higher compressive strength than the parent material foam.

Enhanced Mechanical Performance of Aluminum Glass Fiber Reinforced Foam Material by Cu Modification

“…Similar results had been obtained previously in GFRFs [3]. The average plateau stress of the considered foams in the stroke range of 2 to 16 mm was found to be increasing for glass fibers coated with up to 3 wt.% Cu.…”

“…It is seen that after pressing the shape of the powders have changed and some of the fibers have broken. Limit deformation value of carbamide was examined in the previous study [3]. The determined compaction conditions were applied at a rate of 0.5 mm min −1 .…”

“…Compression tests were conducted by quasi-static loading, in uniaxial conditions along the directions parallel to the compacting directions on foam samples with asobtained sizes, taking into account ASTM E9-09 standard. The energy absorption capacity of obtained foam was calculated from area under the compressive curve in the range of its plateau region [3]:…”

“…Their low density, high strength, and stiffness characteristics make these metallic materials to satisfy the strict requirement of such modern industry fields as automotive, railway, aerospace, biomedical industries, as well as in different segments of other engineering industries [1][2][3].…”

Microstructure and Mechanical Properties of Metal Foams Fabricated via Melt Foaming and Powder Metallurgy Technique: A Review

“…The space holders are firstly mixed with the metal powders. These space holders can be polymeric materials, or salts, such as NaCl particles [ 133 , 134 , 135 , 136 , 137 , 138 ], K 2 CO 3 [ 69 ], carbamide particles [ 60 , 139 ], carbohydrate particles [ 140 ], polymethylmethacrylate (PMMA), etc. [ 141 ].…”
