Strength And Stiffness

Abstract The polymer composite materials properties are clearly determined by their constituent properties and by the micro-structural configuration. Additives and modifiers ingredients can expand the usefulness of the polymeric matrix, enhance the processability or extend composite durability. The fibres are mainly responsible for the performance changing (strength and stiffness properties). The least structurally demanding cases is the arrangement of fibres randomly in polymeric matrix, when equal strength is achieved in all directions. Fibre reinforced polymer materials can be successfully used in a wide range of applications and can significantly improve the characteristics of chemical protection equipments and foster the development of new ones with superior features.

The article presents the results of a study of the rheological characteristics of dispersion-fi lled polymer composite materials (DFPCM) based on LDPE and glass balls of the ШСО-30 brand in a wide range of processing temperatures. For the fi rst time, the rheological properties of dispersion-fi lled polymer composite materials are considered from the standpoint of the formation of the dispersed phase with diff erent types of lattices, functional division of the polymer matrix (φp = Θ + В + М) and the construction of dispersed systems with diff erent types of structures (DS, LFS, MFS, HFS) in terms of generalized parameters (Θ, amid/d). This approach allows us to predict and describe the rheological properties for all DFPCMs with diff erent types of dispersed structures, using a dispersed phase (fi ller) with known geometric dimensions (d), packing density (parameter kpacking and φm) based on this polymer matrix. The infl uence of temperature on the processing technology of DFPCM with diff erent types of structures into products by injection molding has been established.

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.

Translation Practice

Synthetic polymer material is made of polymer composite materials. Plastic, rubber, chemical fiber, building glue and paint are mainly involved in civil engineering. The basic components of the polymer materials are synthetic polymers, which is referred to as superpolymer. Materials of civil engineering made from the polymer or the traditional material modified the preparations are traditionally known as the chemical building materials. Chemical building materials is more and more widely applied in civil engineering, playing an important role in various decorations, waterproof, anticorrosive adhesive, as other civil engineering materials can not be replaced by. The English translation of critical polymer materials is vital, and the translation quality has a direct impact on people's understanding of it. In this paper, using the method of Nord's function plus loyalty translation theory, the author discusses the translation problems of polymer materials, and provides constructive and theoretical basis for translation practice.
