Surf-Free Weaving on Circular Weaving Machines (CWM)
Rocket and space technology is developing on the basis of mass and energy perfection and operational reliability. The need to preserve properties in wide temperature ranges with rapid changes, against the background of various mechanical loads, with their combinations and abrupt changes, requires the use of materials with unique properties. The creation of lightweight heat-resistant composite materials with high characteristics that persist over a wide temperature range was carried out at the Ural Research Institute of Composite Materials. During the development and production of extensively reinforced products from new composite materials in the form of shells, circular-woven multilayer frames were used as a filler. Such frames ensure the maximum interlayer strength of the product material, contribute to reducing the risk of delamination and cracks with combinations of variable force and temperature influences, especially in the areas of stress concentrators. The manufacturing process of circular-woven multilayer frames is the most difficult high-tech task that requires the presence of special circular-weaving machines. Such machines (CWM) are created at the enterprise. A unique technology of "surf-free" weaving has been developed. New composite materials based on round-woven frames have been certified. The technology of manufacturing of circular-woven frames and blanks has been worked out, their serial production is carried out.
