The Matrix

Based on studies of the microstructure of the matrix of cured polymer composite materials and the area of its contact interaction with reinforcing fibers, the hypothesis of its structuring in the microwave electromagnetic field with an increase in the contact interaction surfaces due to an increase in the number of agglomerates with small transverse dimensions and a decrease in porosity in the macro- and mesopore regions is substantiated. These effects can be used as a basis for increasing the strength characteristics and uniformity of their values after exposure to a microwave electromagnetic field. The results of this work can be used in the development of technologies for finishing hardening of products made of carbon and fiberglass for various transport and energy systems.

Energy Saving Technology

Problem statement. At present, the increase in the efficiency of the technology for the production of composite structural elements is associated with high energy costs. In this regard, the implementation of ways to optimize the parameters of the technological process of manufacturing polymer composite materials is of great importance. The purpose of the article is to optimize the modes of impregnation and curing of thermosetting binders and polymer composite materials based on them in combination with the kinetics of gas evolution and control of all stages of the technological process. Results. An energy-saving technology for molding composite structural elements of buildings and structures has been developed, which provides a reduction in the duration of the curing process of polymer materials, depending on the type of binder. The technology makes it possible to control the speed and degree of curing of a thermosetting binder by changing the tangent of the dielectric loss angle and electrical conductivity. Scientific novelty and practical significance. The approach and the electrophysical method for optimizing the modes of impregnation and curing of composite products in combination with the control of all stages of the technological process have been further developed in relation to the elements of composite structures. The permissible values of the curing parameters have been established according to the optimized mode of a number of thermosetting binders: heating rates, isotherm temperatures, and holding time at them. At the same time, the achieved optimal curing times for binders BFOS, LBS-4, ENFB, 5-211B using the new technology is 2.4; 1.8; 3.0; 2.3; 2.0 and 1.2 times less than according to known technologies. The results obtained guarantee the quality of the resulting composite product and are recommended for accelerating the curing process of polymer materials.

Questions of the construction of dispersed structures of polymer composite materials using a generalized model of dispersed filled polymer composite materials (DFPCM) are studied. Using the parameter of maximum proportion of filler (φm) allows you to take into account the size, shape, and distribution of part of the dispersed filler at the same time. The transition to generalized and specified parameters when describing the structure of the DFPCM leads to the possibility of highlighting the optimal criteria for obtaining systems with the highest strength characteristics. The transition to generalized and reduced parameters when describing the structure of DFPCM leads to the possibility of selecting optimal criteria that ensure obtaining systems with the necessary level of rheological, electrochemical, physico-mechanical and other characteristics.
