This invention relates to the construction of light hollow members subjected to substantial internal pressure, such as frame members, struts, tanks or conduits for use in aircraft, including rockets and rocket planes. It is the general object of my invention to provide a construction by which a maximum strength is attained in light hollow members, with a minimum weight of material. In the attainment of this object, I utilize the high tensional strength of small wires, such as fine steel music wires, and I use this wire in a novel manner to reinforce container walls formed of very thin sheet metal or foil. Such fine wires may have a tensile strength as high as 400,000 lbs. per square inch. My invention relates particularly to arrangements and combinations of parts by which these two forms of material may be effectively combined in such a manner as to fully utilize the difficult but desirable qualities of the two materials to the best advantage.
