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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
