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.

4th UKP-Workshop 2017 – Save the Date!

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
