Study of Nano Powder for Improvement the Mechanical Properties of Armor


During this research nano alumina particles are used as reinforce material to improve characterization of armor. The work involves use of polyester resin as matrix. The properties obtained of resulted samples showed clearly improvement. Where values show linear increases in hardness from low value 77.3 gf/mm of pure polyester to high value 81.6 of polystyrene - 30 wt % nano alumina. Values of thermal conductivity greatly influenced by amount of porosity and so on the density of the sample, where pure polyester has low value 0.0661 W/mk of thermal conductivity and polyester – 30 wt % nano aluminapossess conductivity 0.3411 W/mk.
