Abstract : The authors consider materials used in the making of the power shells of motors, the nozzle block, and the thermal shielding skin. The process of winding glass in the form of fibers is noted as the most promising method of making the motor shell. A table is given of the specific strength of various constructional materials, including vitreous plastic based on E and S state fibers and combinations of epoxy resins with metal wires. The possibility of increasing strength, rigidity, and heat resistance of the wound structures is pointed out, by means of a modification of the state of the wire, the use of hollow wire, and boron wire. Graphs are given illustrating growth in the specific strength of certain materials up to 1972, the change in the characteristics of vitreous plastics when solid wire is replaced by hollow, and the dependence of the strength of the wires on the temperature. Laminated materials suitable for high temperature use are described. (Author)
