National Symposium on Rotor Dynamics - IIT Madras

December 19,20,21

Most machines have one or more rotating parts. Rotating machine elements thus form the backbone of industrial infrastructure and therefore play a pivotal role in the growth and development of the country. Rotor Dynamics is the key in design and maintenance of all such rotating machinery. This area has made tremendous strides in recent years.

ObCom 2011 - VIT

September 9

This International Conference is a major event to be conducted following the grand success of series of ObCom conferences during 2003, 2004 and 2006, which were audited by a good number of participants from Academia and Industry across the World. The past ObCom conferences received good contributions from academia, industry and research organizations. Our sponsors included governmental and non-governmental agencies like DRDO, ISTE, DIT, CSIR etc.

RECYCLING OF GLASS FIBER COMPOSITE MATERIAL

Posted by tpapers On 3:22 pm
Abstract:

Because of increasing environmental demands, especially on dealing with products end of life phase, product manufacturers and designers must consider the future disposal of their products. For conventional materials like steel and aluminum well-functioning recycling methods exists. This is not the case for structures of polymer composites, which are used more extensively, especially for structures like vehicles and vessels. Several techniques do exist but they are not yet commercially available. The current disposal methods of polymer composites are landfill and incineration.

Polymer composites are materials, which consist of several materials like fiber, matrix, and additives. This circumstance complicates the Waste treatment of composite materials. Our project deals with Mechanical materials recycling model which is meant to be used as an aid for preparing future disposal of composite materials. In this method certain amount of virgin material is replaced by composite material for specimen fabrication. The sample is tested in UTM to study the mechanical properties and its values are compared against the specimen prepared from virgin material. Generally when recycled material replaces virgin material, mechanical properties such as stiffness and strength are reduced. However by replacing virgin material, 20% of recycled material prove to have lower weight with comparable mechanical properties to virgin alternative.
Many investigations have pointed out material recycling as the best alternative considering environmental effects. This is also valid for polymer composite materials. Since recycling thermoset composite it is important to acquirecomprehensive information about the constituents of these materials.
