This paper defines the structural strength criterion for 4DL-reinforced carbon-carbon materials. For this scheme, fiber reinforcement consists of four groups of reinforcing elements, three of them are located in parallel planes with the angles of 120° between them and the fourth one is normal to them. The paper addresses the first failure of the ma...

The article presents finite element models of the 2xBgu type tread brake for the simulation of extended repeated frictional heating carried out on a full-scale inertia dynamometer. The numerical calculations were conducted for the brake blocks made of two organic composite materials newly developed specifically for this study. The transient tempera...

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.
