Multilayer Composite Material

The article considers the issues of creating composites using long, continuous structures along the entire length of the structure, and short basalt fibers, and, based on them, multilayer composite materials as reinforcement. A mathematical description of the strength properties of multilayer composite materials based on layers of composites using long, continuous along the entire length of the structure, and short basalt fibers as reinforcement is considered. The results of theoretical studies showed that the multilayer composite material has improved properties. The first layer of material, which is a layer of reinforcement made of continuous fibers, provides tensile and bending strength. The second layer of composite material provides thermal insulation properties and compressive and deformation strength. This layer consists of a composite whose reinforcement is short fibers. It is shown that a multilayer composite material, which is a combination of composites created on the basis of long continuous and short fibers, works as a single system. The first layer of the composite, created on the basis of continuous fibers, works in tension and bending, the second layer, created on the basis of short fibers, determines the strength characteristics during compression and deformation. In order to confirm the theoretical results, work was carried out to create composites based on long and short basalt fibers. When creating a layered composite, a heat-insulating plate was used as the first component, which was reinforced with pieces of basalt fiber. For the production of such plates, a plant was developed to obtain pieces of basalt fiber and further uniform distribution of these pieces in a composite plate. A multilayer composite material with improved properties based on long and short basalt fibers is obtained. The composite slab was reinforced with a mesh assembled from continuous basalt fibers.

In this work the effect of five cycles of heating to a temperature of 1000 °C and three cycles of heating to a temperature of 1100 °C on the structure of multilayered composite material consisted of 100 alternating layers of 08H18 and U8 steels was investigated via the methods of microstructural analysis. It is shown that already in the initial state after rolling there was a redistribution of carbon between the layers of the material. Thermal cycling led to a partial redistribution of chromium in the material, a change in the structure and thickness of the layers.

The article presents the results of new views of fiber bonding in a multilayer composite material. New views of fiber bonding based on the obtaining a cross-section by ion beam cut cutting with further quantitative assessment of the main factors, namely the combined effect of hydrogen bonds of mechanical coupling forces and Van-Der-Waals forces, nature of fibrous, mutual arrangement of fibrous, uniformity of fibro distribution, presence of impurities. The combination of effects of the above forces is determined by the length of fibro contacts and uniformity of distribution of contact lines in the cross section of the multilayer fibrous material. In study, area of cut and uniformity of distribution of area of cut fibrous are determined, chalk distribution is estimated at different technologies of preparation of fibrous material. According to the obtained data, mechanical and surface indices of fibrous material are analyzed.

Multilayer Composite Material

In the traditional molding process of laminated carbon fiber reinforced C/C composites - preform, it always causes great damage to a high modulus carbon fiber. Research about key factors for jet puncture in multilayer composite material is proposed in this paper. With the method, carbon fiber is added into the laminating direction of high-modulus carbon cloth by using jet method, so the preform is combined together to improve interlayer fiber connection strength in laminating direction (Z direction). Firstly, the key factors in jet puncture process are investigated. Parameter optimization and dynamic modeling of jet process have been studied to explore the mechanism of jet puncture process. Then a fluid simulation is conducted by studying the formation and distribution of diffusion flow field, jet resistance, penetration ability and jet kinetic energy loss. Finally, the fluid software is used to simulate and obtain the optimal structure of carbon cloth and the nozzle. It is expected that this paper can provide a new and effective approach for Z-puncture reinforcement fibers of laminated composite materials.
