Enhancement in ballistic performance of composite armor through nano ceramic

الملخص EN

In this study, industrial fiber and polymer mixtures were used for high-speed impact (ballistic) applications, where the effects of polymer (epoxy), polymeric mixture (epoxy + unsaturated polyester), synthetic rubber (polyurethane), Kevlar fiber, polyethylene fiber (ultra High molecular weight) and carbon fiber.

Four successive systems of samples were prepared.the first system component made of (epoxy and 2 % graphene and 20 layer of fiber), then ballistic test was applied, the sample was successful in the test from a distance of 7 m.

or more than, by using a pistol personally Glock, Caliber of 9 * 19 mm.

The second system was consisting of (epoxy, 2 % graphene, 36 layers of fiber and one layer of hard rubber), it was succeeded in testing from a distance of 4 m or more than, by using a pistol personally Glock, Caliber of 9*19 mm.

The third system made of mixture (80 % epoxy + 20% unsaturated polyester) and 44 layers of fiber and 2 % graphene as a composite with 20 layers of fiber outside the composite material, it was successful in testing by using a semi-automatic rifle (AK47) Caliber of 7.62*51 mm from a distance of 15 m or more than.

The fourth system was prepared from alumina ceramic plate Al2O3 (from damaged laboratory furnace linings) with composite consisted of (a mixture (epoxy 80% + 20% unsaturated polyester) and 20 % silicon carbide).placed in a cloth bag together.

It was successful in testing by using a semi-automatic rifle (AK47) Caliber of 7.62*51 mm from a distance of 15 m or more than.
