Abstract :
Nowadays, waste disposal, is one of the most important environmental problems. Since the usage of composite materials has put down all areas of industry, recycling processes of composite materials have been becoming of keen interest. As is known, composites are divided into two primary groups: thermoplastic and thermoset materials. The thermoplastics are easily managed with conventional methods of recycling, while it is difficult to do so in the thermoset ones. In this work, glass fiber reinforced polyester (GFRP) particles of waste materials are mixed with pure polyester by certain mass fractions and various particle sizes. The mechanical properties (Elastic modulus and strength) are investigated using tensile and compression tests. It was found that mixing GFRP smashed particles of (2.36mm) size by 10% of its weight with pure polyester increases the modulus of elasticity by 100% compared with the pure polyester keeping the value of failure stress for both tensile and compressive tests.
