Positive Reinforcement

Abstract

This article focuses on the future applications and challenges of nanotube-enhanced composites. In spite of their well-known strength and stiffness, nanotubes have proved incredibly difficult to harness, especially in composites. Researchers have eventually found ways to compatibilize nanotubes by attaching molecules to the nanotube surface. Some formulators compatibilize nanotubes for infusion processes, which pump resin into reinforcing fiber preforms. Electric hybrid car designer Velozzi is working with Bayer Materials Science LLC, a subsidiary of Germany’s Bayer AG, to use nanotube-based composites in its high-performance electric Supercar and its more affordable plug-in hybrid Solo. Lockheed Martin is investigating a complete range of applications for carbon nanotubes in both materials and electronics. The company wants to incorporate nanotubes into its established production methods. Nanotubes improve resistance to impact, fatigue, and microcracking, all properties related to resins. The result is a much stronger and more durable composite.
