AIMPLAS, the Plastics Technology Centre, has completed the research developed in the framework of the project FIBRAGEN in order to develop a new generation of composites reinforced with natural fibres of improved properties.
Several flax crops have been bred during 2012 and 2013 for their analysis and selection with other centres and European universities. When breeding, different varieties of flax have been used.
Researchers have kept in mind some aspects such as the place, the land, season of the year, moisture and temperature in order to analyse if these variables affect the properties of the plants, and at the same time to select those who present better mechanical properties.
The project forgoes techniques which have been used previously for the improvement of the natural fibres’ properties used as a reinforcement of composites. The technique creates the possibility to avoid the use of additives and processes. The knowledge gained of crop conditions and parameters able to stimulate the plants’ gene expression is a step forward to producing materials composed with more controlled properties and less variability.
The participation of AIMPLAS in the project has been in the adaptation of the different varieties of flax harvested for their processing in the correspondent composites and also in the analysis of the mechanical properties of the products that include these flax fibres as reinforcement.
