Investigation on the Influence of Basalt Short Fiber on Thermo-Physical Properties of Aluminium Metal Matrix Composites.
The objective of this research work was to investigate 
on the influence of basalt fiber on the microstructure and thermo-physical properties of Al /basalt short fiber metal matrix composites (MMCs). The MMCs were fabricated by liquid metallurgical technique and the basalt short fiber varies from 0 to 10 wt. %. The developed MMCs were characterized for damping, coefficient of thermal expansion, specific heat and electrical resistance using dynamic mechanical analyzer, thermal mechanical analyzer, differential scanning calorimeter and four probe electrometer respectively. The results shows that the specific damping properties and specific heat increase with increasing basalt fibers addition\ but, electrical resistivity and coefficient of thermal expansion decreased.
Optimization of Coating Parameters on Coating Morphology of Basalt Short Fiber for Preparation of Al / Basalt Metal Matrix Composites Using Genetic Programming
An electroless method of coating copper on basalt fibers using copper sulphate solution is described. The effects of Sensitization time (A), Activation time (B) and Metallization time (C), used for electroless coating, were optimized to obtain a uniform and a continuous layer of copper coating on the fiber. These factors are crucial in the quality of metal matrix composites made with basalt fibers. The objective of the present paper is to investigate the effect of electroless coating parameters in electroless solution on coating morphology of basalt short fibers and optimization of the coating process parameters based on Genetic programming. A mathematical modeling was generated using Genetic programming and the results were validated using DISCIPULUSTM software. This work gains significance from the sense that, with a reasonably minimum number of experiments, a reliable model has been generated, validated and, further, the process has been optimized. Results show that the metallization time has the highest influence followed by activation and sensitization. Confirmation tests were carried out to verify the experimental results. © 2015 Jordan Journal of Mechanical and Industrial Engineering. All rights reserved
Processing and characterization of metal–ceramics functionally gradient materials
Abstract Functionally gradient materials (FGMs) are receiving great attention as they provide optimum thermal and mechanical properties without a discrete interface between two materials. By controlling the chemical composition and microstructure, Ti–TiB2 based FGM was developed successfully in the present work. Microstructural studies have shown a uniform composition and microstructure gradients in the present FGM system. The effect of particle size and SiC additive on the sintering of the FGM were investigated. The bending strength and fracture toughness of the FGMs fabricated using various processing parameters were also measured.
