Corrosion
The US Federal Highway Administration released a study, entitled Corrosion Costs and Preventive

Strategies in the United States, in 2002 on the direct costs associated with metallic corrosion in

nearly every U.S. industry sector. The study showed that for 1998 the total annual estimated direct

cost of cor ....etc

Demineralised water is water completely free (or almost) of dissolved minerals as a result of one of the following processes :

Distillation
Deionization
Membrane filtration (reverse osmosis or nanofiltration)
Electrodyalisis
Or other technologies.

Demineralized water also known as Deionized water, water that has had its mineral ions removed. Mineral ions such as cations of sodium, calcium, iron, copper, etc and anions such as chloride, sulphate, nitrate, etc are common ions present in water. Deioniz ....etc

ABSTRACT
The subject gives a brief look on the suitability of composite leaf spring on vehicles and their advantages. Efforts have been made to reduce the cost of composite leaf spring to that of steel leaf spring. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very replacement material for convectional steel. Material and manufacturing process are selected upon on the cost and strength factor. The design method is selected on the basis of mass production.

Composites materials for aerospace applications
Abstract:
Fibre-reinforced polymer composite materials are fast gaining ground as preferred materials for construction of aircrafts and spacecrafts. In particular, their use as primary structural materials in recent years in several technology-demonstrator front-line aerospace projects world-wide has provided confidence leading to their acceptance as prime materials for aerospace vehicles. This paper gives a review of some of these developments with a discussion of the proble ....etc

Plastic Injection Molding



Plastic Injection Molding

It is a manufacturing technique for making parts from thermoplastic and thermoset materials
In contrast to the extrusion (which makes continuous parts of constant cross section), injection molding make discrete parts (with complex and variable cross section)
Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape.
The mold is made from metal, usually either steel or aluminium

Abstract
In many areas of the world, finding the type of timber or particle board needed to build a good quality wooden board is becoming a problem. As a result, particle board is beginning to be used by many wooden photo laminators. The information provided in this project report relates specifically to the production of an open fishing photo lamination. It is a simple, easily-formed, room worthy thing. Its general-purpose design is suitable for inside the room/office or around the area.
A general basic knowledge in the use of polyest ....etc

ABSTRACT

The coatings and paint industries strive to provide high technology coatings while reducing volatile compounds and energy consumption to provide a finished coating. Conventional curing process uses convection ovens to provide necessary cure. Here the air being heated in a chamber is circulated by using blowers inside the chamber. This process is time consuming and has high power requirements.

Infrared curing, an alternative for convection curing is one of the fastest growing technologies in the coating industry. It appli ....etc

Thermal shock on interfacial adhesion of thermally conditioned Glass fiber/epoxy

The fiber/matrix adhesion is most likely to control the overall mechanical behavior of fiber-reinforced composites. An interfacial reaction may result in various morphological modifications to polymer matrix microstructure in proximity to the fiber surface. The interactions between fiber and polymer matrix during thermal conditioning and thermal shock are important phenomena.

Thermal stresses were built-up in glass fiber reinforced epoxy c ....etc

PROTECTIVE COATINGS FOR CONCRETE BRIDGES

Protection of structures is very important for increasing the life of the structure. There is a growing national concern about premature deterioration of our concrete infrastructure projects such as bridges, aqueducts etc. requiring early repair and/or replacement. Use of protective coatings will increase the durability and hence the life of these structures. As most of these structures are made up of concrete and steel, the role that coatings play in protecting the surfa ....etc
