A process for the manufacture of an explosively-bonded composite structure comprising a substrate, a metallic cladder and an intervening interlayer between the substrate and the cladder; the cladder and the interlayer having a waveless interface therebetween, the process comprising (A) forming a non-bonded composite structure comprising in combination, (a) a substrate having a first side; (b) an interlayer of a material compatible with the substrate, and having (i) a thickness T1; (ii) a mass M1; (iii) a first side adjacent to the substrate at a distance D1, therefrom; and (iv) a second side; (c) a cladder having (i) a thickness TC; (ii) a mass MC; (iii) a first side adjacent to the second side of the interlayer at a distance D2 therefrom; and (iv) a second side; and (d) an explosive mixture adjacent the second side of the cladder; and wherein D1 is equal to or less than 2T1; D2 is equal to or less than TC; and MC is equal to or greater than M1; and (B) detonating said explosive mixture. The method produces one or more totally flat interfaces, which avoids the formation of deleterious waves and the associated inherent problems of cracking and incorporated intermetallics. The method also allows of the use of thin interlayers, which is of value when such interlayer materials are expensive.
