Abstract
A multidimensional woven, resinous impregnated, rocket nozzle structure composed of fibers running along the longitudinal axis of the nozzle and positioned radially in conformance with the general shape of the nozzle with a weaving fiber under tension and running circumferentially and radially normal to the said longitudinal axis to interlock with said longitudinal fibers in at least three directions.
Claims1
A multidimensional woven rocket nozzle structure comprising a nozzle body of predetermined configuration having an inlet, an outlet and a throat section therebetween, said configurated body being composed of (1) fibers running generally in the direction of the longitudinal axis and positioned radially for dimensional conformance with the general shape of said configurated nozzle;
- (2) a weaving fiber starting at one end of said configurated nozzle and proceeding continuously in a direction normal to said longitudinal axis with a controlled tension in order to position said longitudinal fibers in accordance with the desired radial dimensional relationship, said weaving fiber running radially and circumferentially in a predetermined weaving pattern along the length of the longitudinal axis of said body and interlocking with said longitudinal fibers in at least three dimensions;
- (3) said longitudinal and said weaving fibers are composed of a material selected from the group consisting of silica, carbon, graphite and and glass fibers;
- and (4) a thermosetting resinous impregnant permeating the interstices of said longitudinal fibers and said weaving fiber.
