Effect of rice husk surface modification by LENR on the mechanical properties of NR/HDPE reinforced rice husk composite

Surface modification of rice husk (RH) with alkali pre-treatment (NaOH solution 5% w/v) was carried out at the initial state to investigate the effect of surface treatment of fibre on the surface interaction between fibre and rubber. Further modification of RH surfaces after alkali treatment was usi...
