 The study investigates the effect of surface treatments on the mechanical properties of low-density polyethylene, LDPE, jute composites, and found that alkali-silane treatment of jute fibres led to a more than 30% improvement in mechanical properties when reinforced to untreated LDPE, while melaic and hydride addition improved the properties by more than 45%.
