Sažetak
Increased demand for use of sustainable and biodegradable natural materials, thereby reducing environmental pollution, has encouraged wider production of biocomposites. For this reason, composite materials made from sustainable polylactide (PLA) polymer and Spanish broom bast fibres, which were used as a system reinforcement, were designed and manufactured. Spanish broom is a Mediterranean plant that is used for production of technical fibres of flax-like properties. Spanish broom fibres were modified to improve their mechanical and thermal properties. The type of performed modification affected the strength of the final composite material. The fibre-reinforced composite material modified with nanoclay and citric acid shows the highest increase in strength, by 135 % compared to the fibre reinforced composite material modified with nanoclay only. The elongation at break of the fibre reinforced composite material modified with the addition of a crosslinker shows an increase of 43.7 % over pure PLA, indicating an increase in the toughness of such materials. The addition of nanoclay to the system caused a decrease in the value of the released heat and, consequently, a lower flammability of such materials. As each production process entails the generation of a certain amount of waste, the possibility of using residues after the maceration process as biomass in bioenergy production has been investigated.
