CNT-INFUSED ARAMID FIBER MATERIALS AND PROCESS THEREFOR
First Claim
1. A composition comprising a carbon nanotube (CNT)-infused aramid fiber material comprising an aramid fiber material of spoolable dimensions, a barrier coating conformally disposed about the aramid fiber material and carbon nanotubes (CNTs) infused to the aramid fiber material, wherein said CNTs are uniform in length and uniform in distribution.

Abstract
A composition includes a carbon nanotube (CNT)-infused aramid fiber material that includes an aramid fiber material of spoolable dimensions, a barrier coating conformally disposed about the aramid fiber material, and carbon nanotubes (CNTs) infused to the aramid fiber material. The infused CNTs are uniform in length and uniform in density. A continuous CNT infusion process includes:(a) disposing a barrier coating and a carbon nanotube (CNT)-forming catalyst on a surface of an aramid fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the aramid fiber material, thereby forming a carbon nanotube-infused aramid fiber material.
