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.
