WKI-Webinar Surface modification of cellulose-based fibers for fiber-reinforced composite materials

09.01.2014
The characteristics of plastics can be optimised through the application of cellulose-based fibers as reinforcing components.

These fiber-reinforced composites can be used in all situations in which the structural elements are subjected to special requirements. Due to the strong potential of these materials in lightweight construction applications, they are currently of particular interest to the automotive industry. Diverse applications are, however, also possible in the construction and furniture industries.

Due to their natural origins, cellulose-based fibers possess characteristics which, until now, made them difficult to use. They demonstrate a strong variability of their morphologic properties as well as a pronounced hygroscopicity. This leads to dimensional alterations through swelling of the material. The hydrophilic surface of cellulose-based fibers impedes the binding to the matrix materials – this has a strong influence on the mechanical properties of the composite material.

Various pre-treatment measures on the cellulose-based fibers enable the influencing of the chemical characteristics of the fiber surface as well as the moisture absorbency and the shape variability of the fibers. The characteristics of the resulting fiber-reinforced composites can also be altered through a modification of the fibers. The influencing of the fiber-matrix adhesion is of particular importance here, as it has a strong influence on the mechanical characteristics of the composites.

The Fraunhofer WKI’s current Webinar on 21.01.2014 provides an overview of the current research status and the projects being carried out at the Application Centre for Wood Fiber Research into surface modification. The Online Seminar is primarily directed at participants from the fields of automotive manufacture, construction and the furniture industry

We warmly invite you to take part in the Webinar and to discuss the subject with us.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
