investigation into the behavior of nano-composite tubes at ballistic impact

In this study, the behavior of filament wound nanocomposite tubes under transverse impact loading is investigated. experimental specimens were manufactured using epon 828 resin with 0.5, 1.5 and 3 weight percentages of nano silica. because of the varying nanosilica weight per-centages in the specimens, different behaviors were observed; increasing the weight percent-age of nanoparticles increased impact strength. a ballistics test was performed with a gas gun, with projectile entry and exit speeds carefully recorded. all tests were carried out with projec-tiles with a mass of 9.3 grams at a speed of 130 meters per second. failure of fiber, output velocity, damage area, and effects of varying percentages of nanoparticle content on resistance of the cylindrical shells under ballistic impact at various velocities are derived and presented. the final results are analyzed and compared.
