Effect of particle size on mechanical properties of the recycling compact disks reinforced epoxy

Abstract EN

The recycling of CDs or DVDs (compact disks) as a filler in polymer composites can be used in many engineering applications such as electrical, automobile, and building applications.

In the present paper, composite materials were prepared of epoxy resin reinforced with three different particles size (600˂d˂850, 200˂d˂600, d˂200 μm) of recycling of CDs or DVDs (a very thin aluminum layer is used to record information).

Hand lay-up technique was conducted to produce composite material samples.

Different types of tests, such as tensile, bending, impact, and hardness were applied on these samples.

The mechanical characteristics of the composite samples were analyzed.

The finding observed that smaller chopped of CDs or DVDs reinforced epoxy had better tensile, bending, hardness, and impact properties.
