Accelerated ageing of surface modified flax fiber reinforced composites

The overall aim of this study is to evaluate application-oriented potential of biocomposites made of surface-modified flax fibers for use in engineering thermoplastics. The scope of the study includes analysis of the effect of a partially bio-based epoxy-coating, a silane treatment and a combined ep...
