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.
Advances in the fabrication of titanium metal matrix composite
Abstract This paper describes recent developments in the processing of continuous fibre reinforced titanium alloy metal matrix composite. Used selectively, MMCs can have a dramatic effect on performance and weight. They combine the exceptional strength and stiffness of a ceramic with the many advantages of a metal matrix, which include elevated temperature capability, impact resistance, and environmental stability. Titanium MMCs have passed through the initial material research stages and the basic mechanical performance criteria are now well established. Further progress towards commercial exploitation now depends on detailed process definition and cost reduction.
TRANSVERSE STRENGTH OF METAL MATRIX COMPOSITES REINFORCED WITH STRONGLY BONDED CONTINUOUS FIBERS IN REGULAR ARRANGEMENTS
Abstract The composite limit flow stress for transverse loading of metal matrix composites reinforced with a regular array of uniform continuous fibers is calculated using the finite element method. The effects of volume fraction and matrix work hardening are investigated for fibers of circular cross section distributed in both sqyare and hexagonal arrangements. The hexagonal arrangement is seen to behave isotropically with respect to the limit stress, whereas the square arrangement of fibers results in a composite which is much stronger when loaded in the direction of nearest neighbors and weak when loaded at 45° to this direction. The interference of fibers with flow planes is seen to play an important role in the strengthening mechanism. The influence of matrix hardening as a strengthening mechanism in these composites increases with volume fraction due to increasing fiber interaction. The results for a power law hardening matrix are also applicable to the steady state creep for these composites. The influence of volume fraction on failure parameters in these composites is addressed. Large increases in the maximum values of hydrostatic tension, equivalent plastic stain, and tensile stress normal to the fiber-matrix interface are seen to accompany large increases in composite strength.
