Recyclability of Particulate Natural Fiber Composite Waste on Hemp/Epoxy composite- Mechanical and Drilling Characterization. 2020-28-0398

In automobile industries, the usage of natural fiber composites (NFC) becomes one of the most inevitable materials in engineering applications because of its better properties such as less expensive, high strength to weight ratio and stiffness. In recent days door trim panels, wheel arch, rear hatch, roof liner and bonnet insulation in vehicles were fabricated by NFC. Once the vehicle attains ELV (end-of-life vehicles) metals from the vehicle were recycled but the NFC’s were not recycled and dumped as scrap. Hence the main objective of the present research was to recycle the NFC waste as reinforcement in the hemp/epoxy composite. This work examines the effect of reinforcing the composite waste in hemp fiber in various weight percentages (0, 5, 10 and 15). The mechanical characteristics such as tensile, flexural, impact and hardness were carried out for the prepared composite as per ASTM standards. The ability of the fabricated composite against drilling operation was studied by varying the process parameters such as feed and speed according to the design of experiment (DOE). The Addition of 10 wt% (300 microns) of the composite waste as the reinforcement influence and enhance the mechanical properties of the composite. The distribution of the reinforcement and the bonding of the matrix were analyzed using a Scanning electron microscope (SEM).
