16 February 2017 - Impact of different variables on the properties of flax-based composites

Within the project EU KBBE “FIBRAGEN- flax for improved bio-materials through applied genomics” we had the opportunity to analyse relationships between the genotype, the fibre properties and their performance in composites processed with three contrasting methods in respect to severity (twin-screw extrusion and injection moulding (TSE).

Major results are that composites processed with less aggressive processing techniques have a strong dependency of the growing conditions (year effect) which can be explained by different fibre morphology. Although there is a strong dependency of the mechanical properties of the composites of the processing technique, fibre varieties could be identified showing relatively higher/lower mechanical properties in all different composites over two years. This knowledge forms a valid basis for further breeding programs of flax for composite purpose.
