Sound absorption performance of EFBMF panel for building acoustic material
… of EFBMF panel is at 90 % absorbing for 100 MF coir panel, 85 % absorbing for 90:10 coir panel and 80 % absorbing for the other three (3) panels (50:50 coir, 100 EFB dust and 80:20 dust) in the reverberation chamber. In conclusion, EFB and MF wastes are another viable alternative raw fibers that …

An approach of using polymer natural fiber composite for vibration and flammability control
… and flammability properties of kenaf fiber and coir fiber reinforced polypropylene were investigated. Different fractions of composites with 10wt%-40wt% coir fiber (CF) and kenaf fiber (KF) content were prepared by using brabender mixer at 190 °C. The 3wt% MAPP was added during the mixing. The …
