Abstract
A generally tubular shroud of rectangular cross-section having flat side walls formed by inner and outer tubes of rectangular cross-section spaced apart to provide a substantially uniform space therebetween, a flat aluminum-boron carbide sandwich received in and substantially filling the spaces at the four sides of the shroud. The inner and outer tube walls are in pressure contact with the inner and outer surfaces of the sandwiches. The side walls of the tube and sandwiches are interlocked by transversely extending elongated channels formed in the shroud walls including the inner and outer tube walls and the sandwiches. The invention includes a method in which after assembly, the parts are expanded in a die by very high pressure hydraulic pressure by means of a flexible bag, establishing the pressure contact and suitably folding end portions of the inner and outer tubes.
