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: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
