Some aspects regarding the static behavior of basalt in the machine building industry

MATEC Web of Conferences, 2017

Basalt is a material available in big quantities in nature. It has a low price and can be used in various domains. It can be relatively easily extracted from natural deposits and processed by means of melting. Melted and recrystallized basalt has demonstrated promising behavior with regards of its use in manufacturing, as reported in the literature. This work aims to present some aspects regarding the opportunity of using basalt in manufacturing the subassemblies of machine-tools. The research was made using grey cast iron and steel parts as reference for a comparative study. The researches presented in this work were focused on analyzing the behavior of basalt parts submitted to static stress. Testing methodology, specific measuring apparatus used, experimental test data records, data processing and resulting conclusions are presented in the paper.

Experimental Investigation on Mechanical Properties of Basalt-Core Reinforced Materials

IRJET, 2022

A composite material is a combination of two or more different materials; it gives superior quantity than its constituents. Composite materials not only used for structural applications but also in various other applications such as automobile, aerospace, marine, etc. This work describes an experimental mechanical characterization campaign on composite made out of unidirectional Basalt raw with 8 layers. The strength of the material is observed by performing mechanical tests. A core material is introduced in combination with basalt to check the mechanical properties of raw basalt with core as ingredient. In addition to that the influence of core on the strength and thickness of the material is also evaluated by knowing the percentage improvements in strength were the cost of the material also reduces due to the addition of core material. The work has used raw materials from commercial catalogues with no further modification. Compression mould is the manufacturing method used to prepare the sample. After mould process the sample is tailored to ASTM standards for testing

Thesis for the Degree of Doctor of Philosophy in Solid and Structural Mechanics

2016

Metal cutting is today one of the leading forming processes in the manufacturing industry. The metal cutting industry houses several actors providing machine tools and cutting tools with a fierce competition as a consequence. Extensive efforts are made to improve the performance of both machine tools and cutting tools. Performance improvements are not solely restricted to produce stronger and more durable machine tools and cutting tools. They also include knowledge about how the machine tools and cutting tools should be used to perform at an optimum of their combined capacity. Information about the dynamic properties of the machine tool cutting tool assembly is one of the aspects that carries the most potential in terms of productivity increase and process reliability. This work presents a methodology to synthesise the dynamic behaviour of a machine tool and cutting tool assembly based on component models of the machine tool and the cutting tool. The system is treated as an assembly...

Study on the Usage of Special Materials for High-Strength Parts Used in the Machines Manufacturing Industry

ANNALS OF THE ORADEA UNIVERSITY. Fascicle of Management and Technological Engineering., 2016

Whereas formerly metallic materials were used extensively and for various purposes in the machines manufacturing industry, nowadays new materials are sought that can replace the "conventional" machines manufacturing materials with new ones. This is especially challenging in areas where parts need to be able to withstand very tough conditions, such as high temperatures or large forces applied to them. The current paper intends to analyze some of the most widely used materials for high-strength applications. A special focus in this regard is on the one hand in fiber-reinforced composite materials with the polymer matrix and on the other hand on basalt. The most important properties, processing technologies and applications of these materials are analyzed and discussed and conclusions are drawn regarding their compatibility with the intended purpose.

OPTIMISED PRODUCT DEVELOPMENT OF BASALT FIBRE COMPOSITE TUBES BY MEANS OF FINITE ELEMENT ANALYSIS

In the present paper, the topic is the result of a partnership of the University of Bayreuth and several small and medium sized economics. With support by the government (project ZIM) high-end composite tubes reinforced by basalt fibres, were researched and developed. The Conclusion is a more effective usage of the strength potential of basalt fibres. The examined applications were tubes used in conveyor belts, which were enhanced with FE-simulations. A fundamental for a realistic simulation was an intensive corporation with the involved industrial partners regarding the boundary conditions. Providing characteristic values for strength criterias based on their experience was an essential part. In consideration of the current manufacturing technology, optimised fibre composite tubes were established. The optimisation focusses on an advanced layer structure considering the applied boundary conditions. Restraining the tube ends and the existing loads are reflected in several simulation...

Mechanical Properties of Basalt Filaments

Fibres & Textiles in Eastern Europe, 2007

tion of some structural parts (plagioclase, magnetite, pyroxene) and due to the non-homogeneity of melt. Utilisation of the technology of continuous spinning overcomes the problem of unevenness and the resulting filament yarns are appli cable in the textile branch. It is possible to use these yarns for the production of planar or 3D textile structures for composites, special knitted fabrics and also as the sewing threads. The application of basalt yarns as sewing threads is especially attractive. It is possible to use these threads for the joining of filtering bags for hot media, and for very aggressive chemical environments, etc. In this contribution selected properties of basalt filaments are presented. As starting material the laboratory prepared filaments were used by us. Mechanical properties were investigated at room temperature, and then tempered to 50, 100, 200, 300, 400, 500 °C, and in some experiments up to 800 °C. The analysis of the fibrous fragment evolved during the ab...
