Scaling effects in the threaded pieces made of the spatially reinforced carbon-carbon composite materials

The paper presents results of studying the impact of the strength and stiffness scaling effects in modern spatially reinforced carbon-carbon composite materials on bearing capacity of the products made from them. These materials are widely used in equipment operating under extreme conditions of simultaneous loading with force and temperature factors. When designing such products, it becomes necessary to understand the influence degree of the frame damaged during machining on observed properties of the material used, including dimensions, at which it is required to consider reduction in strength and stiffness, as well as the value, which could reduce the considered properties.
