The relevance of the study is due to the deterioration of the environmental situation in the world associated with an increase of plastic waste, which determines the feasibility of developing methods for their involvement in recycling for the production of plastic products. Thereby, this article is aimed at studying the patterns of changes in the physical and mechanical and thermophysical properties of polymer composites based on recycled polypropylene filled with rice husk in the absence of compatibilizers. The leading approach to the study of this problem is the determination of the modulus of elasticity in flexure, tensile strength at break, strain-to-failure, and bending strain, bending temperature under load and Vicat softening temperature, Charpy V-notch impact energy and Izod impact strength, as well as the thermophysical parameters of polymer composites. The article shows that with an increase in the content of rice husk in a polymer composite based on recycled polypropylene, an increase in the modulus of elasticity in flexure occurs. Filling polypropylene with rice husk slightly reduces the tensile strength and significantly reduces the elasticity of the polymer. Recycled polypropylene has a higher Charpy V-notch impact energy than Izod impact strength. Filling the polymer with rice husk leads to a decrease in impact strength according to both Charpy and Izod, and with a compound content of more than 5 phr, both of these indicators are almost identical. In this case, there is a slight increase in the onset temperature of the composites, which determines their thermal stability during processing. It was revealed that polymer composites containing 2-10 mass parts of rice husk are characterized by an increased degree of crystallinity of the polymer phase. The materials of the article are of practical value for the processing of recycled thermoplastic polymers, as well as the creation of biodegradable polymer composites.

Wood Polymer Composites

Wood polymer composites (WPC) have well proven their applicability in several fields of the plasturgy sector, due to their aesthetics and low maintenance costs. However, for plasturgy applications, the characterization of viscoelastic behavior and thermomechanical and thermophysical properties of WPC with the temperature and wood filler contents is essential. Therefore, the processability of polymer composites made up with different percentage of wood particles needs a better understanding of materials behaviors in accordance with temperature and wood particles contents. To this end, a numerical analysis of the viscoelastic, mechanical, and thermophysical properties of composite composed of high density polyethylene (HDPE) reinforced with soft wood particles is evaluated.

Abstract The urgency of anticorrosive protection issues of ship hulls, deck structures, mechanisms, etc., as one of the main problems of the naval, is noted. One of the options for its effective solution is the use of coatings based on various polymer-composite materials. The authors substantiate the need for a preliminary assessment of the reliability and durability of such coatings, taking into account high humidity and aggressiveness of the operating environment, the corrosion of the repaired surfaces, the cyclic effect of stresses and alternating temperatures, etc. Proceeding from this, using the example of multicomponent polymer-composite compositions of the “Sprut” type, methodological approaches to the study of the polymer-composites durability for ship repair are considered. Their comparative characteristics are given. A mathematical model for assessing the durability of polymer-composite materials and coatings based on them is described, and the experimental studies’ results of their durability under static and cyclic stress in the operating temperature range are presented. The obtained results of theoretical and experimental studies are important for development of the methodological approaches to increasing the durability of mastic deck coatings based on polymer composite materials and the development of practical guidelines for the use of adhesives in shipbuilding and ship repair. The research results make it possible to develop new and improve the adopted technologies for the use of protective coatings on the structures of ship hulls and deck structures. Thus, the problems of the water transport operation, associated with the anti-corrosion protection of ship hull and deck structures and their repair, can be solved.
