Abstract

Polymer wastes produce and consume a lot of carbon fiber reinforced polymers (CFRP) and glass fiber reinforced polymers (GFRP) as they are used in various fields such as construction, aviation, oil and gas, sporting and wind industries. These materials are highly used in production throughout the world. Furthermore, people may end up throwing these composites materials into rivers, etc., and composite materials are not disintegrate fast enough. In addition, the high cost of sending waste to landfill and natural quality charge per kilogram, which is RM10/kg. The purposes of this study are firstly, to study the suitable fiber size for concrete fabrication of the recycled glass and carbon fibers by using mechanical recycling method. Secondly, to evaluate the mechanical properties of the concrete prepared using recycled glass and carbon fibers. Thirdly, to perform morphological analysis on the fractured surface of the concrete using scanning electron microscopy (SEM) and crystalline structure using X-Ray Diffraction (XRD). The fiber size at 50μm for concrete fabrication is seen to be suitable by using this mechanical recycling method. The ultimate tensile strength and Young’s modulus of concrete with recycled glass fiber is the highest among normal concrete and concrete with recycled carbon fiber which is 9.06 MPa and 6.92 MPa respectively. Hence, the concrete with recycled glass fiber inclusion had yielded an extraordinary improvement of about 10.49% in the tensile strength and 53.78% of Young’s modulus as compared to normal concrete. Lastly, perform morphological analysis on the fractured surface of the concrete using scanning electron microscopy (SEM) and X-Ray Diffraction (XRD). From the SEM micrograph, it shows clearly the recycled glass fiber had strong bonding with concrete. Other than that, a good dispersion of recycled glass fiber in concrete was found which tends to give high strength and good bonding. From the XRD analysis, concrete with glass fiber concrete, it produced many peaks. This proved that the present of Ca3Si2O7 in concrete with recycled glass fiber. In such way, the bonding between Ca3Si2O7 in concrete and the SiO2 in recycled glass fiber were strong strength. This study indicates clearly a viable option for waste management for recycled glass fiber and recycled carbon fiber materials through the development of an economical final recycling application that will contribute to a more sustainable fibre-reinforced polymer composite industry.
