Bending Behaviour of the Composite Materials Made by Recycling of the CDs and DVDs

Abstract

Abstract: The paper describes the aspects concerning a methodology of recycling of CDs (compact disks), DVDs to develop a new composite material made of a polyester resin reinforced with chopped material of CDs, DVDs. It is known that polycarbonates are mainly used to manufacture of CDs, DVDs while a very thin aluminium layer is additionally used to record information. The first of all, the hand lay-up technology is used to prepare a board made of the composite material involved. Then, the composite specimens were cut from the board and subjected to the flexural test (three points method). Herein, the mechanical characteristics of the specimens were analysed. Moreover, the photos acquired by using a metallographic microscope are presented to discuss about the homogeneity of the composite. structure. Finally, some applications of the new composite material tire proposed by taking into account the experimental results shown and above. all, the recycling necessity of the large quantity of CDs / DVDs wastes.
