PREPARATION AND MECHANICAL PROPERTIES OF CARBON NANOTUBE ALIGNED CARBON FIBER/EPOXY COMPOSITES

Abstract

Abstract: Carbon fiber/epoxy composites filled with carbon nanotubes were prepared by HF (high frequency electric field) induction method. The influence of the frequency on the mechanical properties of the composites was studied, and the microstructure of the composites was observed. The results show that the carbon nanotubes have obvious orderly alignment along the electric field in the resin-rich region. The interlaminar shear strength, compressive strength and flexural strength of the composite laminates can be increased by 28.9%, 28.83% and 15.01%, respectively. The surface roughness of the composites fracture surface increased with HF treatment, and the interface state of resin and carbon fiber was improved.

Key words: carbon nanotubes, composites, HF (high frequency electric field) induction, alignment
