thousands if not millions within a short span of time. In terms of cancer and general human health, plastic has become an important issue. Plastic is a concern for both the environment and for the health conscious. Plastic is a synthetic material created by combining materials derived from sources such as petroleum, natural gas or coal. These polymers then must be combined with additives to give the finished product properties such as flexibility or toughness (Life Without Plastic and Mama Mundo Inc., 2013)

bottle selfmanufacture technology, with three additional lines commissioned in Australia. „Blowfill‟ has enabled CCA to design new lightweight primary and secondary packaging, PET bottles, and has enabled the saving of thousands of tonnes of raw materials. CCA‟s Mount Franklin Easy-Crush Bottle went into the market in 2011as the lightest weight Australian-produced 600mL water bottle made with 35 percent less PET plastic and a carbon footprint that is 27% less than the previous Mount Franklin bottle

CHAPTER 1 INTRODUCTION The machining conductive as well as nonconductive advanced engineering materials such as glass, ceramics, quartz, granite and composite materials are difficult to machine by usual process. These materials are having wide range of applications in the field of automobile, aerospace and defense field. So processing of these materials is necessary with easy and economical way. Hence Hybrid Machining Process (HMP’s) like ECSM is evolved and is shown in fig1.1. ECSM is the combination

punch and die surfaces. Due to that, the sheet metal will deformed into the desired shape. Some of the most common outcomes in deep drawing process are tearing and wrinkling or the formation of uneven height at the top rim of a drawn part due to the material anisotropy. Wrinkling as become a serious obstacle to forming quality and part functions and finally results in scraps. This defects are caused due to change in parameters like

surface. Aerogels as a whole are made by creating a gel then extracting the solvent with supercritical fluid extraction. This leaves a very porous, low-density solid. Due to their porous nature, aerogels are considered to be the finest insulation materials available. Silica aerogels are good insulators, but will flake apart and produce dust in the Mars atmosphere. For this reason, all-polymer aerogels should be used over their silica-based counterparts. They can be created as thin, flexible films and

3. Materials This section will describe the materials that were used in the laboratory experiments that will be presented in this thesis. 3.1 Portland CEMENT Portland cement is composed of a combination of limestone and either shale, clay, sand, or iron. These materials are ground and blended together and heated in a kiln from 2600o F to3000o F. This causes the materials to fuse together to create clinker. Cooled clinker is then ground with gypsum (CaSO4*2H20). The addition of gypsum controls the

attempted by this unique process. Friction Stir Welding can be used to join aluminum sheets and plates without filler wire or shielding gas. Material thicknesses ranging from 0.5 to 60 mm can be welded from one side at full penetration, without porosity or internal voids. Nowadays welding materials is chosen for non-ferrous materials and it has a broad range of materials. In this paper we have identified the effects of different process parameters on friction stir welding of aluminium 1100 and aluminium
