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

Nevertheless their durability and stability don't reach that of carbon fibers. epending on the application we are therefore combining carbon with various bio-based textile fibersexplains Prof.
Hans-Josef Endres head of the Application Center for Wood Fiber Research. The fibers typically exist as fabrics that are placed on each other accordingly
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.
For instance how can expensive carbon fibers be extracted from the matrix and recovered? With the hybrid materials theye engineered the scientists are already considering in advance how these can be reprocessed
The researchers will also present fiber form-pressed components for the automotive industry there. Fibers inside these parts are embedded into a thermoplastic matrix#plastic that is

#Scientists Stretch Electrically Conducting Fibers to New Lengths An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be stretched reversibly to over 14 times their initial length and
The research team is using the new fibers to make artificial muscles, as well as capacitors whose energy storage capacity 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;
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
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
which allows for repeated stretching of the fiber. hink of the buckling that occurs when an accordion is compressed,
the Robert A. Welch Distinguished Chair in Chemistry at UT Dallas. e make the inelastic carbon nanotube sheaths of our sheath-core fibers super stretchable by modulating large buckles with small buckles,
These amazing fibers maintain the same electrical resistance, even when stretched by giant amounts, because electrons can travel over such a hierarchically buckled sheath as easily as they can traverse a straight sheath.
said the structure of the sheath-core fibers as further interesting and important complexity. Buckles form not only along the fiber length
but also around its circumference. hrinking the fiber circumference during fiber stretch causes this second type of reversible hierarchical buckling around its circumference,
even as the buckling in the fiber direction temporarily disappears, Liu said. his novel combination of buckling in two dimensions avoids misalignment of nanotube
and rubber core directions, enabling the electrical resistance of the sheath-core fiber to be insensitive to stretch.
By adding a thin overcoat of rubber to the sheath-core fibers and then another carbon nanotube sheath,
the researchers made strain sensors and artificial muscles in which the buckled nanotube sheaths serve as electrodes
resulting in a fiber capacitor. These fiber capacitors exhibited a capacitance change of 860 percent
when the fiber was stretched 950 percent. o presently available material-based strain sensor can operate over nearly as large a strain range,
Liu said. Adding twist to these double-sheath fibers resulted in fast, electrically powered torsional
or rotating artificial muscles that could be used to rotate mirrors in optical circuits or pump liquids in miniature devices used for chemical analysis,
