Overview

Fibrenet forms a unique collection of projects

The research in Fibrenet consortium takes place in the crossroads of three application areas and various methods that span over large range of different size scales as illustrated in the figure below. The figure also presents the distribution of our Individual Research Projects (IRPs) in the different crossroads.

The application areas represented in Fibrenet and related to bio-based fibres are biocomposites, Overviewpaper and packaging applications and biomedical applications. In our consortium, the biomedical applications concentrate on biomedical textiles, such as wound healing textiles, and cell scaffolds. All the application areas are important for the European industry although combining them in the fibre-based research is rather unique.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Our aim is find commonly beneficial solutions to processing fibres and optimizing their properties - irresspective of the application area. In order to truly master the fibre poperties and their effect on the properties of the end-product the research spans over many size scales from naoscale functionalization and modelling to large scale production.

 

 

 

 

 

 

 

 

 

In order to reach the objectives, a versatile set of know-how and organizations have been brought together under the Fibrenet consortium. The table below summarizes some of the core know-how and methods related to Fibrenet offered by participating organizations.
