Patent number: 5242098
Abstract: It is known to form a composite laminar metal structure, wherein two or more overlapping metal plates (11, 12, 21, 22, 23, 31, 32) are metallurgically bonded at their interfaces, impelling the plates (11, 12, 21, 22, 23, 31, 32) together by means of detonating an explosive charge (19), bonding of the plates (11, 12, 21, 22, 23, 31, 32) at selected areas (13) being prevented by covering the plates (11, 12, 21, 22, 23, 31, 32) at the selected ares (13) with a stopping-off material. The present invention improves this by providing metal sheet (14, 24, 34) which is placed in intimate contact with the stopping-off material, the metal sheet (14, 24, 34) being capable of metallurgically bonding to an adjacent metal plate (12, 21, 23, 32) at each selected area (13).
