Carbon Fiber Research

UK CAER operates one of the only production lines for spinning experimental fibers and precursor carbon fiber in the United States. Our team is uniquely positioned to partner with industry on the development of new fibers and new carbon fiber products.

Carbon Nanotubes

UK CAER has been involved with multi-walled carbon nanotube (MWCNT) synthesis and research since the mid 1990s. Our research has explored many of the desirable properties that MWCNTs exhibit, including strength, stiffness, electrical conductivity, and thermal conductivity.

Polymer Processing

For nearly 20 years, UK CAER has been involved in polymer processing research. Working with both thermosets and thermoplastics, research in this area has focused on mixing fillers into the polymers to improve their mechanical and electrical properties.

Carbon Fiber Research

Improving Carbon Fiber Technology

Carbon fiber is the material of the future — a next-generation version of aluminum. Its properties are often considered the holy grail in manufacturing. Carbon fiber is a low-weight, high-strength, corrosion resistant material that can conduct electricity. The University of Kentucky Center for Applied Energy Research (UK CAER) is home to the largest carbon fiber spin line at any institution in North America. Over the past decade, our researchers have built a solution spinning line that draws visitors, collaborators, and research partners from across the Commonwealth, the nation and the world. And they are here for one thing: to lean on UK CAER’s carbon fiber research team as they seek answers to some of the toughest questions facing the industry.

Exploring the Potential of Carbon Nanotube Technology

When carbon nanotubes (CNT) were first discovered in the early 1990s, it sparked a revolution in materials science. These incredible structures have an array of fascinating electronic, magnetic and mechanical properties. CNT are at least 100 times stronger than steel, but only one-sixth as heavy, so nanotube fibers could strengthen almost any material. Nanotubes can conduct heat and electricity far better than copper. CNT are already being used in polymers to control or enhance conductivity and are added to anti-static packaging. For nearly two decades, UK CAER scientists have been involved in multi-walled carbon nanotube (MWCNT) synthesis and research. During that time, the carbon materials group researched many of the desirable properties that MWCNTs exhibit, including strength, stiffness, electrical conductivity, and thermal conductivity. Additionally, the group has worked extensively to make multi-walled carbon nanotubes more accessible by driving down their cost through continuous production technology.
