Novel Continuous Carbon Nanofibers for the Next Generation Lightweight Structural Nanocomposites

Abstract

The goal of this research was to establish applicability and effectiveness of novel continuous carbon nanofibers as nanoreinforcement in advanced organic matrix composites. The specific objectives were: (1) demonstrate applicability of continuous carbon nanofibers for delamination suppression in advanced PMC laminates; (2) explore manufacturing and characterize mechanical behavior of carbon nanofiber reinforced epoxy matrix nanocomposites. Continuous carbon nanofibers were successfully manufactured and used to reinforce interfaces in specially designed aerospace grade carbon-epoxy laminates. Static and fatigue Mode I and II fracture mechanics and edge delamination testing were performed. Substantial improvements in delamination toughness, mechanical strength, and fatigue life were observed for the first time. Pioneering multilayered carbon nanofiber reinforced nanocomposites were manufactured and evaluated. It was demonstrated that continuous carbon nanofibers may provide unique advantages for structural nanocomposite applications.
