Effects of Alkali-Silane Treatment on Tensile Strength of Woven Kenaf Reinforced Polypropylene Composites

Natural fibre reinforced plastics (NFRP) had been developed by researchers all over the world nowadays because natural fibre offers a lot of advantages such as low cost and does not threat the environment over glass and carbon fibres. However, limitations occur in order to produce the NFRP in mass d...
