“…To perform mechanical tests using the prepreg technology,4 series of flat rectangular carbon fiber samples with a size of 20x250x1.3 were produced (for PCM with technical wax in the matrix: 20x250x3.4): a control sample without viscoelastic components (1 series), with anaerobic polymer material Loctite 638 (2 series), with organosilicon polymer material Unisil-9628 (3 series) and with technical wax in the matrix (4 series) [12,13].…”

Increasing the pace of development of the Arctic zone, among other tasks, requires the attraction of significant production resources to improve the transport network, in particular, road construction equipment and technological equipment. Extreme climatic conditions, including low air temperatures and strong winds, are features of the Arctic zone. In this regard, there is a need to form a methodological basis for the development of construction and repair materials for use in the Arctic. To solve this problem, based on the results of mechanical tests at temperatures of +20°C, -30°C and -50°C, the possibility of using carbon fiber plastics with various types of hybrid matrices for the manufacture of mechanical engineering products operating in extreme conditions of the Arctic and the creation of reinforcing linings during their repair. The indicators of manufacturability during repairs under the conditions of constant exposure to negative temperatures using polymeric materials are considered.

“…Polymer composites based on fibred carbon materials and epoxy resins are widelyused in the production of rocket-space engineering, the aircraft industry, mechanical engineering, in the production of road and construction machines, etc. [1][2][3][4].They are used in the manufacture of structural elements, which require a combination of high strength, rigidity, durability and minimum weight [5][6][7][8][9].Currently, in the manufacture of parts from carbon fiber reinforced plastics, prepreg technologies and methods of direct molding are used [10][11][12].The principle of direct molding methods is that the process of impregnating the reinforcing compound and the molding processof the partare combined into a single technological operation.This leads not only to a reduction in the duration of part manufacture, but also to a reduction in energy and labor costs and, as a consequence, reduce the cost of technology.Direct molding methods include: vacuum infusion, resin transfer molding (RTM), resin film infusion, etc.…”

Calculation of the Thermal Stress when Subjected to an Electric Current on Glass and Carbon Fibers with Copper Coatings

2021

Two types of fibers (carbon and glass) are considered, as an object of research, on the surface of which a copper coating is applied with a thickness of 100 nm using magnetron sputtering technology. A finite element model of a coated fiber was built and simulated in the COMSOL Multiphysics software. As a result of the calculations, the values of the temperatures, arising during the passage of electric current on the surface of the fibers and copper coating, have been determined. This calculation makes it possible to simulate the thermal heating modes occurring in parts of fiberglass and carbon fiber reinforced plastics in the process of curing. As a result of calculations, it was found that copper coating significantly improves electrical conductivity, which is especially important for glass fibers, since its conductivity is considerably lower than carbon. The use of copper coating in the production of parts from fiberglass allows to regulate their thermophysical properties within a wide range.

The experimental research results of porosity, interlayer shear strength and flexural modulus of carbon fiber reinforced plastics (CFRP) depending on the chemical composition of the binder and molding technology are presented. The standard vacuum infusion technology and its two modifications differing in vacuum bag assembling order and initial material are applied. The best characteristics of CFRP are achieved with the improved technology №2 using two vacuum bags. The differences between two compounds with various hardener chemical nature are compared. Optimal characteristics are obtained by using compound with diaminodiphenylsulfone hardener.
