The use of flax shives as reinforcement in biocomposites
Abstract
Flax shives (FS) are the main by-product of the flax scutching industry and represent approximately 50 % of dry stem weight, making them a widely available resource having very low added value. In this study, raw flax shives have been fragmented by ball milling (sample FS50) and knife milling (samplesFS250 and FS500) and used as reinforcing material in polypropylene injected composites. The biochemical composition of reinforcing samples in monosaccharides and lignin shows no variation after comminution, but a 50 % drop in crystallinity index was measured between raw flax shives and the ball-milled sample. The morphological study of reinforcing materials (length, aspect ratio) after processing were correlated to composite tensile properties showing an increase in Young’s modulus with particle size, from 22.7 to 32.7 GPa for FS50 and FS500 respectively, the latter reaching 90% of the flax fibre reinforced composites. Flax shives provide promising mechanical performances.
