The Tensile Strenght Properties Effect of Rice-Husk Ash as on The Composite of Plastic Drinking Bottle Waste

Abstract

Rice-husk ash has a potential to be filler in composite. The study on rice-husk ash utilitation as afiller in polyethylene terephthalate (PET) matrix of plastic drinking bottle waste was conducted in order to find the ratio of rice-husk ask and PET matrix that would result the best tensile strength, which was characterized by using scenning electron microscopy (SEM). In this study, the PET of plastic drinking bottle waste firstly was cut into smaller pieces and was extruded with the temperature of 265 o C. Then, it was mixed with rice-husk ash on ratio of PET plastic drinking bottle waste and rice-husk ash of 95:5, 90:10 and 85:15. After that, it was extruded at temperature of 265 o C before it was pressed by hot press at temperature of 265 o C for five minutes. The highest tensile strength was achieved at 3,462 MPa with elongation at break a round 143,75 % and young’s modulus of 348,82 MPa for the ratio of 85:15.
