REINFORCED STRUCTURAL COMPOSITES.
Abstract
A technique of fabricating W bodies of increased strength was sought. Vapor deposition of unstressed W on stressed W wires was selected as the method for attaining the objective of the program. Equipment was designed and constructed for the vapor deposition of W metal from a gaseous mixture of WF6 and H onto a heated mandrel surface. A set of operating conditions was developed for the deposition of high quality W in the form of tubes of one inch outside diameter. While these tubes had good microstructures, taper existed in the wall thickness. Two tubes were fabricated which were reinforced longitudinally with stressed W wires. The microstructure of the W deposited around the wires was influenced by the presence of the wires. Deposition was initiated from the mandrel and wire surfaces. The technology of producing reinforced tubes was not developed to the point of initiating testing. (Author)
