Influence of Structural Defects in Carbon Fibers on Their Sensor Properties Evaluated Using Scanning Electron Microscopy

Method of Predicting the Polymer Composites’ Properties Using Neural Network Modeling

“…In this study, the SkyScan 1172 X-ray microtomograph was used to analyze the structures of polymer composite materials, which allowed to visualize internal defects and damage that occur during the production or maintenance of products made of polymer composite materials. According to the works [10,13] it is known that the durability and reliability of parts and products made of polymer composite materials depend on their internal structure and the nature of damage caused by external loads.…”

“…Various methods of non-destructive testing are used to assess the quality of components manufactured by using vacuum infusion technology, including structural analysis methods [8][9][10][11][12]. The detection of internal defects in composite materials by non-destructive methods is an important requirement, both for quality control at the production stage, and for monitoring their durability during operationand maintenance.…”

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.…”

“…By adjusting the chemical nature and thickness of the metal coating, it is possible to vary the thermophysical characteristics of reinforcing materials and composites based on them within a wide range.The authors of studies have shown thatit is expedient to use copper with a thickness of 100 nm as a metal coating material [9,14].…”

Research of Kinetic Impregnation Process Based on the Structure of Reinforcing Filler

“…Composite Materials are becoming more popular gradually replacing traditional materials with extra strength, lighter weight, and thermal properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Many composites' industries are exploring the use of fiber-reinforced composites in all applications which includes aerospace, automotive and water transport, construction industry, toys, instrumentation, medicine, etc.…”
