Bending properties of carbon fiber nanocomposites with lamination structure of reinforcement

摘要

Advanced materials with excellent performance are in high demand in modern industry. Carbon fiber composites offer a number of advantageous mechanical properties. A significant improvement in fiber-reinforced composites can be achieved by dispersing a very small amount of nanofiller in the resin. Vacuum-assisted resin transfer molding (VARTM) is one of the most important processes for producing reinforced plastics. In this work, several composite samples were fabricated with the infusion of carbon nanofibers (CNFs) into the epoxy matrix using VARTM process. Using scanning electron microscopy (SEM), it was confirmed that CNFs were well dispersed in the resin. Bending tests were performed to investigate the mechanical properties of the samples, and SEM, to examine the fracture surfaces.
