Creation of Structural Polymer Composite Materials for Functional Application Using Physicochemical Modification

Abstract

The various aspects of physicochemical modification of the components of structural materials of functional application based on classical composites and nanocomposites are analyzed. Potential applications of such materials are briefly described. Ultrasonic cavitation treatment is considered as a basic method of physical modification when obtaining the indicated classes of composites. The influence of ultrasonic treatment modes on the technological and operational properties of reactoplastic polymers, as well as on the hardening of reinforced composites based on them, is investigated. Technical means of ultrasonic cavitation processing of liquid binders and polymer composites based on them are briefly described. An effective spectrum of interrelated structural and technological parameters of ultrasonic treatment has been characterized, which is established by calculation and experimentally-statistically. The design issues of the technological processes of obtaining polymer composites of functional application are analyzed. The efficiency of creating carbon fiber composite materials, as well as the prospects for creating of these materials based on reinforcing fabric with nanomodified fillers, is described. The methods of obtaining functional nanomodified carbon-composites with improved physicomechanical and operational properties, in particular with increased strength and electrical conductivity, are characterized. The effectiveness of the ultrasonic treatment and production of nanomodified thermoplastic composite materials by extrusion method is considered. Some issues of forming products from intelligent polymer composites are analyzed. The results of the survey can be used in the design of advanced technologies for the creation of functional polymer composites of functional application.

Modeling the Structures of Oriented Macrofiber Polymer Composites as Capillary‐Porous Bodies

“…Also, based on the developed approach, PCMs modeling is possible using both chemical modification and combined physicochemical modification of the components of PCMs including OFFs of rope and woven types [73,74]. At the same time, the modification should ultimately lead to improved PCMs operational characteristics [75] and also contribute to increasing the productivity of molding and energy saving when receiving reinforced composites due to the ordering of their structure, improvement of interfacial interaction at the "fiber-polymer matrix" interface, and reduction of voids in the formed composite [76].…”

Physical and Chemical Prerequisites for Efficient Mechanical Processing of Composite Materials

“…В качестве преимущества можно отметить простоту технической реализации, независимо от формы обрабатываемой детали. Однако пропускание ультразвука в КМ может вызывать модификацию структуры и свойств [40]. В частности возможно уменьшение размеров полимерных молекул в результате их деления, образование новых структурных образований и химических связей.…”

“…The use of composite materials based on polymers is an important factor in improving the efficiency and successful development of leading industries [ 1 ]. At the same time, the rapid development and improvement of composite materials, as well as the constant need for modern production in them, urgently require the creation of competitive materials with predictable properties [ 2 , 3 ] and the development of high-quality polymer composites with specified technical characteristics [ 4 , 5 , 6 ].…”
