ДОСЛІДЖЕННЯ ДОЦІЛЬНОСТІ ЗАСТОСУВАННЯ СКЛОПЛАСТИКОВИХ ТА БАЗАЛЬТОПЛАСТИКОВИХ СТЕРЖНІВ ДЛЯ АРМУВАННЯ ВИРОБІВ З КАМЕНЮ

Abstract

Purpose. The purpose of this work is to study the feasibility of using different types of composite materials for natural stone products reinforcement by comparing their strength characteristics. Methodology. Recommendations for the preparation of samples for strength research have been implemented and described. Recommendations for the preparation, adjustment and commissioning of fixed assets and materials used in the study are given. The constituent elements of the experiment aimed at determining the strength characteristics of the samples are developed and described. Based on the results of the obtained data, the values of the basic strength parameters during the destruction of the samples under the action of bending loads have been calculated. Results. The study of the technology of stone products reinforcement allows solving a number of problems related to improving the quality and competitiveness of stone manufacturing. A holistic and scientifically sound study of reinforcement technology allows an array of empirical data and developing the optimal order of its use. Scientific novelty. Systematization and review of existing methods of natural stone products reinforcement are performed and methods of their optimization with the help of modern composite materials are offered. The expediency of using fiberglass and basalt-plastic composite materials for the purpose of reinforcing stone products has been empirically investigated. The expediency of using fiberglass and basalt-plastic composite materials for natural stone products reinforcement by comparing the obtained values of strength characteristics has been substantiated. Practical significance. The practical significance of the obtained results lies in the possibility of their application in order to simplify, modernize and improve the technology of stone products reinforcement for its widespread introduction as one of the basic technologies in the conditions of stone processing enterprises. However, the research results confirm the fact of the expediency of using composite reinforcement (especially basalt-plastic) to improve the strength properties of stone products.
