TL;DR: In this article, the capacity of flax/PLLA (poly(l-lactide)) biocomposite (20% and 30% fibres by weight) to be recycled was investigated.
Abstract: The biocompostability of natural fibre-reinforced biopolymers, also known as biocomposites, makes them attractive alternative to glass fibre-reinforced petrochemical polymers. The aim of this work is to study the capacity of flax/PLLA (poly(l-lactide)) biocomposite (20% and 30% fibres by weight) to be recycled. Mechanical properties were evaluated initially, and shown to be similar to those of glass/PP and superior to hemp/PP and sisal/PP composites. Then after repeated injection cycles tensile properties were shown to be conserved until the third cycle. Matrix degradation and fibre aspect ratio were followed using molecular weight measurements, thermal and rheological analyses, image analysis of sections and SEM fractography. These techniques revealed a lower molecular weight, lowering of glass transition temperature, reduction of fibre length, and separation of fibre bundles with injection cycles. Nevertheless, the property retention after three cycles under extreme recycling conditions (100% recycling with no added virgin polymer) indicate the promising recyclability of these materials.

TL;DR: In this article, wood flour is converted into thermoplastics through proper benzylation treatment, which introduces large benzyl group onto cellulose and partially deteriorates the ordered structure of the crystalline regions.

TL;DR: In this paper, the effect of maleic anhydride on the swelling and mechanical properties of plant fiber polymer composites has been assessed and the impact strength and Shore-D hardness have been found to be higher in maleic-anhydride-treated fiber composites than the untreated-fiber composites.

TL;DR: In this article, sisal fiber reinforced polypropylene (SF/PP) composites were prepared by injection molding using a pre-coating technique that they have developed earlier, and the composite specimens were subjected to hot water immersion treatment at 90 °C for different durations.
