| 摘要 |
The invention relates to an armoured shaped body comprising a multi-layer composite plate, which has a layer made of high-strength steel and a layer made of titanium or a titanium alloy as well as a layer made of a hard material of great hardness deposited on the titanium or titanium-alloy layer. The production of such an armoured shaped body takes place in such a way that composite plates, which are cut to length from the composite strip made of steel and titanium or a titanium alloy produced by roll-bonding, are shaped into shaped bodies, onto whose titanium or titanium-alloy layer the hard-material layer in the form of powder is then deposited in particular by means of flame spraying. Such a shaped body has a high gunfire resistance, because in the event of gunfire the hard-material layer enlarges the impact area of the bullet, so that the kinetic energy of the bullet is distributed over a large area on the shaped body. Accordingly, the kinetic energy of the bullet is converted by a larger area of the composite plate into work of deformation, so that the risk of the bullet penetrating the composite plate is reduced. |
