Investigating Environmental Weathering of CNF/CNT/ Thermoplastic Polymer Synthesized using Additive Manufacturing

Sahle-Demessie E., Zhao Amy, Stephen Chady, U.S. Environmental Protection Agency, US

Additive manufacturing (aka, 3D printing) is an emerging technology for making a new class of multifunctional nanocomposites for many niche items such as medical implants, and a wide range of industrial designed components. Additive manufacturing [...]

Nanocomposite optimization using polymer-wrapped carbon nanofibers

Papantonakis M.R., Barbano M.E., Ou W., Gorzkowski E.P., McGill R.A., US Naval Research Laboratory, US

We present results for carbon nanofibers modified by physisorption with a range of polymer modifiers and then dispersed in different polymeric hosts with mechanical advantage and other applications in mind. In contrast to covalent bonded [...]

Microcharacterization of Creep Behavior of Carbon Nanofiber Reinforced HDPE Nanocomposites using a Depth Sensing Method

Xu S., Liu T., Tangpong X.W., Akhatov I., Zhong W-H., North Dakota State University, US

Depth-sensing indentation at micro- and nano-scale levels is a useful tool for material characterization due to its simplicity. There are many well-established methods for determining local mechanical properties including elastic modulus, hardness, and fracture toughness [...]

Improved RF Characteristics of Carbon Nanotube Interconnects with Deposited Tungsten Contacts

Vyas A.A., Madriz F., Kanzaki N., Wilhite P., Tan J., Yamada T., Yang C.Y., Santa Clara University, US

Carbon Nanofibers (CNFs) grown by Plasma Enhanced Chemical Vapor Deposition (PECVD) are potential next-generation interconnect materials due to their high current capacity. We designed and fabricated a test structure for RF characterization of CNF interconnects [...]

Direct Numerical Simulation of Carbon Nanofibre Composites:

Yamanoi M., Maia J.M., University of Minho, PT

For functional applications of carbon nanotube and carbon nanofibre as composites, technologies of how to control orientation, dispersion and distribution are important would be a break-through if they were developed. So far, most of the [...]

Carbon Nanofiber Reinforced Carbon/Polymer Composites

Joshi M., Bhattacharyya A., Indian Institute of Technology, IN

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The [...]
