#Researchers invent super-elastic conducting fibers to make artificial muscles, sensors, and capacitors A University of Texas at Dallas research team has made electrically conducting fibers that can be stretched reversibly to more than 14 times their initial length and
whose electrical conductivity increases 200-fold when stretched. The research team is using the new fibers to make artificial muscles,
as well as capacitors with energy storage capacity that increases about tenfold when the fibers are stretched. Fibers and cables derived from the invention might one day be used as interconnects for super-elastic electronic circuits
robots and exoskeletons having great reach, morphing aircraft, giant-range strain sensors, failure-free pacemaker leads,
and super-stretchy charger cords for electronic devices. Wrapping carbon nanotube sheets into fibers In a study published in the July 24 issue of the journal Science,
the scientists describe how they constructed the fibers by wrapping lighter-than-air, electrically conductive sheets of tiny carbon nanotubes to form a jellyroll-like sheath around a long rubber core.
The new fibers differ from conventional materials in several ways. For example, when conventional fibers are stretched,
the resulting increase in length and decrease in cross-sectional area restricts the flow of electrons through the material.
But even a iantstretch of the new conducting sheath-core fibers causes little change in their electrical resistance, said Dr. Ray Baughman,
senior author of the paper and director of the Alan G. Macdiarmid Nanotech Institute at UT Dallas. One key to the performance of the new conducting elastic fibers is the introduction of buckling into the carbon nanotube
sheets. Because the rubber core is stretched along its length as the sheets are being wrapped around it,

"It was very important that the fibers formed smaller pores than the tip size.""While the widths of pores in other membranes are a few hundred nanometers,

If you combined bio-based textile and carbon fibers you can obtain extremely light yet very sturdy components. ightweightis an important buzzword in automotive engineering and just as important in the aerospace sector too.
Carmakers are increasingly counting on fiber reinforced synthetics. These fibers which are embedded into the synthetic matrix give the material its additional durability.
Exactly which material you choose to use depends on its eventual application. Thus primarily carbon fiber is used in Formula 1 racing.
However one drawback is its high price; even its processing can be tough. These are the reasons why carbon fiber-reinforced plastics (CFRPS) have still not yet found their path into wide-scale serial production so far to date.
Glass fibers on the other hand are priced certainly reasonably but heavy by comparison. But this may soon change thanks to some new research approaches by researchers at the Application Center for Wood Fiber Research HOFZET of the Fraunhofer Institute for Wood Research the Wilhelm-Klauditz-Institut WKI

and are embedded by the plastic matrix. e use carbon fibers in those areas where the part undergoes intense mechanical stress;
in other areas it natural fibers. This way we can leverage the strengths of the respective fibers
and get rid of the disadvantages to a great extent. he outcome: the parts are cost-effective have a very high degree of durability possess excellent acoustic properties
and can be processed as well as possible into fabrics this is also referred to as izing the surface of the fiber
Specialized surface treatments or coatings are intended to ensure that the fibers can be combined and interact in the best possible way with the matrix or the plastic mass.
y ensuring that the fibers bond to the matrix optimally we can increase the durability of the materials by up to 50 percentendres explains in concrete terms.
and carbon fibers when it comes to use textile fibers for reinforcement the researchers are treading on virgin territory.
Because when it comes to recycling fiber composite materials are a proverbial ough nut to crack.
