Aluminum Silicon Carbide Graphite hybrid composite finds automotive and aerospace appliions because of tailor made enhanced hardness and solid lubriion imparted by the reinforcements SiC and graphite respectively. Parametric studies conducted
The basic idea is to obtain a hybrid composite by stir casting method by mixing Aluminum LM25, Graphite, fly ash and Silicon carbide in varying proportions. The Tensile, compression, Hardness, wear tests were performed and evaluated. Aluminum LM25 has
AlSiC, pronounced "alsick", is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics..

Abstract: In recent year''s aluminium and aluminium alloys are widely used in automotive industries. These are light (density of about 2.7 g/cm 3), having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity.  V. N. Gaitonde, S. R. Karnik, M. S.

The results showed that some graphite flakes have reacted with silicon present in commercial aluminum powder and formed silicon carbide (SiC) at temperatures above 252 C. SiC has great effect on
We may use a composite of graphite, carbon and silicon to provide affordable anode capacity with minimized anode volume expansion [93,94]. A silicon/graphite/amorphous carbon (Si/C) composite with a low silicon content in a core–shell structure was synthesized by the spray drying method [ 76 ].
The molten silicon inﬁltrates throughout the boron carbide preform, ﬁlls the pores and reacts with graphite. The reaction between silicon and graphite mostly leads to the formation of silicon carbide  and, as a result, the composite is mainly made of B 4
The reinforcement silicon carbide was varied from 0 to 12 Wt % in a step of 3 and the graphite is kept constant at 4 Wt %. The mechanical behaviour of the composite was investigated. The particles distribution and elemental mapping was carried out with field emission scanning electron microscopy and energy dispersive spectroscopy.
An in-situ hot pressing/solid-liquid reaction process was developed for the synthesis of dense polycrystalline Ti3SiC2 ceramics using Ti, Si, and graphite powders as starting materials. The present work demonstrated that this process was one of the most effective and simple methods for the preparation of dense bulk Ti3SiC2 materials. Lattice constants of a=3.068 and c=17.645 are …
A high-performance Si/carbon/graphite composite in which Si nanoparticles are attached onto the surface of natural graphite by carbonization of coal-tar pitch is proposed for use in lithium-ion batteries. This multicomponent structure is favorable for improving Li + storage capability because the amorphous carbon layer encapsulating Si nanoparticles offers sufficient electric conductivity and
