Now a day’s composite materials are taking very important role in industrial growth. Composite materials are widely used in Automobiles, aerospace, submarine and also in other major fields, due to their special characteristics like light weight, high strength, stiffness, corrosion resistance. The determination of Coefficient of Thermal Expansion (CTE) of MMCs is important to aid its usage in high temperature environment as in the case of automobile combustion chamber. In these applications the stability of the composites over a long period of operation is a critical design considerationPresent work deals with the thermal property evaluation of the Al alloy / alumina metal matrix composite developed using the Stir Casting with chilling route technique. LM 26 Al alloy is being selected as the matrix material as it is a potential alloy for automotive piston applications. Al alloy / alumina MMCs was cast under end chilling technique by dispersing the reinforcement from 6 to 12 wt% the steps of 3% to study the variation in its thermal properties. At the same time chill material is also changed (Copper and MS) for different composition of MMCs cast to study the thermal behavior variations. After casting the required MMC, test specimens were prepared as per the standards to conduct thermal conductivity (K) tests and coefficient of thermal expansion (CTE) tests. Above tests were repeated for different composites containing different weight % of dispersed cast using different chills.

The successive civilengineering disasters in recent years make the use of geomaterial for disaster prevention popular. Geogrids, one type of geo-material, function as soil reinforcement. This study uses polypropylene (PP) fibers to wrap high strength polyester (HSPET) fibers, forming the PP/HSPET fasciated yarn. PP fibers are acid-resistant and alkali-resistant, and thus serve as the skin of the fasciated yarn. HSPET fibers, the core of the fasciated yarn, protect and prolong the service life of the resulting geo-material products. Finally, the influence of mechanical parameters on the appearance and strength of the fascinated yarn is explored.
