Abstract
The environmental and economic concerns of our day are driving component manufacturers to develop durable and cost-effective composites. In this sense, carbon fiber (CF) waste generated in the aerospace industry can be used to develop lightweight composites for use in the inner fender of a passenger car. In this study, recycled chopped carbon fibers derived from clean CF scrap were blended with a recycled Polypropylene (PP) matrix derived from disposable masks collected during the COVID-19 pandemic. To improve the interface characteristics of the reinforcements with the matrix, anhydride grafted polyethylene (PE–Fusabond® ) has also been added to the composites. After manufacturing composites using a twin-screw extruder, characterizations were carried out by bending and Charpy impact tests. From the mechanical characterizations, CFs remarkably enhanced the elasticity modulus of the composites, while Fusabond improved the elongation capacity of the composites. Moreover, both reinforcements significantly improve the impact resistance of the composites. In addition, microstructural observations were performed. Scanning electron microscope (SEM) fractography done on the failed specimens showed that crack bridging and plastic deformation of the matrix were the main toughening mechanisms.
