Structure and properties of poly (lactic acid)/Sterculia urens uniaxial fabric biocomposites

► Newly identified Sterculia urens uniaxial fabrics used as a reinforcement. ► Sterculia urens uniaxial fabric reinforced poly (lactic acid) (PLA) biocomposites were prepared by a two-roll mill. ► Treatment on Sterculia urens uniaxial fabrics improved the mechanical and thermal properties of biocomposites. ► SEM of fractured surfaces treated with silane-coupling agent biocomposites showed flower-like structure. ► PLA/Sterculia urens uniaxial fabric reinforced biocomposites with excellent engineering properties useful for food packaging.
