Abstract

Significant composite strength improvements have been achieved using highly aligned and dense carbon nanotube fibers with low resin concentration, but these remain ac-cessible only to aerospace applications [1]. The potential of carbon nanotubes for high volume production compo-sites has been in the development of multifunctional com-posites. Examples are polymer matrix composites contain-ing dense networks of nanotubes [2,3] or carbon nanotube forests. The piezoelectric nanotube networks impart ther-mal and electrically conductive pathways into a normally insulating composite. The advantages include thermal management of spe-cific hot spots, localized curing or heating, strain sensing, and damage sensing. One of the challenges in deploying these materials is understanding the long term durability of the network. A series of hygrothermal exposures were con-ducted on a polymer matrix composite containing multi-wall carbon nanotubes grown from the surface of the fi-ber. The performance of the composite is evaluated as a function of degradation using both thermal, mechanical, electrical and moisture uptake measurements.
