摘要: Abstract This work was to apply the vacuum-assisted resin transfer molding (VARTM) process and use aluminum hydroxide inorganic nanoparticle impregnation (INI) improve mechanical properties water resistance of kenaf fiber reinforced composites. As a novel technique, two-step used in fabrication composites, including alkali retting loading. After retting, cellulose content fibers went up 94.2%, ash 2.7%. The tensile strength modulus individual were 810 MPa 13.5 GPa, respectively. results showed that, with loading amount 2.2% hydroxide, elasticity, rupture, composites made INI-treated increased by 67.2%, 55.7%, 32.5% 36.3%, respectively, compared those from un-treated fibers. When employed, thickness swelling 24-h submersion reduced 19.7 6.3%, moisture contents after conditioning 5.8% 1.9%, 18.3% 6.6%, improvement makes possible replace glass for automotive application.
