Abstract
Physicochemical and Mechanical Performances of Technical Flax Fibers and Biobased Composite Material: Effects of Flax Transformation Process
Highlights
The use of flax fibers in composite materials retains great attention and is growing in industrial sectors such as automotive, sports and leisure [1]
The aim of our study is to investigate biochemical, physicochemical, and mechanical properties of technical flax fibers from six modalities to evaluate the impact of transformation processes on final properties of the associated composite materials

Summary
The use of flax fibers in composite materials retains great attention and is growing in industrial sectors such as automotive, sports and leisure [1] This interest is due to their physical properties (density and specific mechanical properties) which can be competitive with glass fibers [2]. Flax fibers are renewable resources [3], unharmful to health unlike glass fibers [4] and supposedly low cost [5] They mainly consist of cellulose, hemicellulose, pectin and lignin which are the most widespread polymers on earth [6]. Technical flax fibers consist of a combination of elementary fibers interconnected at their interface by pectin [11] They are obtained by scutching flax stem and hackling flax bundles. Once this flax tow has been scutched and hackled, the fibers are separated through these weak interfaces and the fibers are thinner and contain fewer cells in their bundles [13]
