ABSTRACT
This study encompasses research involving Charpy impact tests and hardness tests conducted to determine the mechanical properties of carbon nanofiber (CNF) reinforced samples used in epoxy matrix materials for composite structures. The utilization of CNFs as filler materials to enhance the mechanical strength of composite structures holds significant importance, particularly in industries demanding advanced technologies such as aerospace, space exploration, automotive, and marine engineering. This study evaluates the mechanical properties of epoxy composites with varying concentrations of CNF additives, presenting the comparative results of Charpy impact tests and hardness tests.
The results of the Charpy impact tests indicate that epoxy composites with 0.8 wt % CNF additives demonstrate the highest performance, whereas those with 1.2 wt % CNF additives exhibit the lowest performance. Similarly, the outcomes of the hardness tests corroborate that epoxy composites with 1.2 wt % CNF additives possess the lowest hardness values.
This study contributes to understanding CNF-reinforced epoxy composites' mechanical properties and emphasizes their potential in industrial applications. Furthermore, focusing on standard test methods for determining the mechanical properties of CNF-reinforced epoxy composites provides guidance for future research in this field.
