    Abstract

    Biobased materials are becoming of increasing interest as potential structural materials for the future. A useful concept in this context is the fibre reinforcement of materials by stiff and strong fibres. The bio-resources can contribute with cellulose fibres and (bio) polymers from hemicelluloses. This offers the potential for stiff and strong biocomposite materials, but these have some limitations and obstacles to full performance. The focus will be on the structure, strength and stiffness of cellulose fibres, on the (unavoidable) defects causing large reductions in strength and moderate reductions in stiffness, on the packing ability of cellulose fibres and the related maximum fibre volume fraction in composites, on the moisture sorption of cellulose fibres and the related mass increase and (large) hygral strains induced, and on the mechanical performance of composites.
