Composites are combinations of two more separate materials on a microscopic level, in a controlled manner to give desired properties. The properties of a composite will be different from those of the constituents in isolation.

When two materials are combined together to form a composite, one of the materials will be in Reinforcing phase and the other material will be in Matrix phase. Typically, reinforcing material in the f..............etc

In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers in the present scenario. Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The suspension leaf spring is one of the potential items for weight reduction in automobiles as it accounts for 10% - 20% of the unsprung weight. This achieves the vehicle with more fuel efficiency and improved riding qualities.

Metal matrix composite

A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. The other material may be a different metal or another material, such as a ceramic or organic compound. When at least three materials are present, it is called a hybrid composite. An MMC is complementary to a cermet.Contents

Deterioration of reinforced concrete structures due to corrosion of steel is a cause of global concern. The losses due to corrosion every year run into millions of rupees and any solution to this universal problem of corrosion has a direct bearing economy of the country. It is estimated that about 30-40 percent of steel produced each year is used to replace corroded material.
In recent years, the construction industry has seen an increased demand to reinstate, rejuvenate, strengthen and upgrade existing concrete structures. This may be attrib..............etc
