Abstract

The epoxy matrix of a carbon fiber/epoxy composite was modified with multiwall carbon nanotubes (MWCNTs) to improve the matrix dominated thermomechanical and structural properties of the composite. Effects of improved dispersion and nanotube length on enhancement of the composite were investigated experimentally. A pronounced improvement of the composite properties was achieved with 0.5 wt% of MWCNTs with the use of a dispersion enhancing block copolymer. In addition, longer nanotubes resulted in further improvement of properties. Noticeable improvements were observed in in-plane compressive strength and compressive strength after induced damage compared to composites without nanotube reinforcement.
