Strength of the Joint of an Anisotropic Composite and a Cylindrical Element of the Exhaust System of Road Vehicles

Calculation of the bending of electromechanical aircraft element made of the carbon fiber

“…To obtain expressions for 2 {} N and 3 {} N , it suffices to perform a cyclic replacement of the indices in (6).…”

“…Since most reinforced plastics are characterized by a pronounced anisotropy of mechanical properties, the possibility of using methods developed for isotropic materials to calculate products from them is excluded. The physical and mechanical properties of anisotropic materials are described in extensive scientific and engineering literature, including [1][2][3][4][5][6][7][8].…”

New Composite Materials With a “Liquid” Matrix

“…Composites manufacturing technology with several different types of "liquid" matrices is described in the article [12]. Initially, a prepreg was made from carbon fabric and an epoxy binder, and then the "liquid" matrix material was applied to one of the layers of the package (for example, to the second), as shown in Fig.…”

“…The theoretical framework for the creation of nature-like polymer composite materials are analyzed in the articles [11][12][13][14][15][16][17][18]. These authors formulated the main requirement when selecting the components of such composites: this is a good compatibility of polymer matrices with each other, provided the absence of their mutual solubility.…”

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

“…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.…”
