Investigation of the mechanical properties of carbon nanotubes and glass fiber reinforced high density polyethylene hybrid composite materials

In recent years, research and synthesis processes on carbon nanotubes (CNTs) have become widespread with the development of composite materials in our country and the world. CNTs are so lightweight and high strength material. Because of high tensile strength and abrasion resistance of glass fiber, is used as a strengthening in plastic-based materials. In this work, high density polyethylene (HDPE) and 0,5; 1 and 1,5% by weight of CNTs were mixed with acetone. The acetone was evaporated after mixing in the ultrasonic mixer and magnetic stirrer. Mixtures of HDPE and CNTs have become completely homogeneous by passing it through a twin-screw extruder. The composite plates made from glass fiber, HDPE and CNTs by hot press machine. Plates were cut by laser cutting machine, so test samples were obtained. This samples were tested and then their mechanical properties have been examined. The result of the experiments showed that reinforcement of glass fiber and all proportions of CNTs increased strength values. With these reinforcements, provided a good strength increase on the material.
