Tensile Strength Properties of Rice Husk-Rice Husk Ash Filled Plastic Drinking Bottle Waste Hybrid Composite with the Addition of Glycerol as Plasticizer

This study aims to determine the tensile strength properties of rice husk-rice husk ash filled plastic drinking bottle waste hybrid composite with the addition of glycerol as plasticizer. Hybrid composite was made using extruder at 265 oC by mixing plastic drinking bottle waste with 100 mesh particle size of rice husk and rice husk ash with the ratio between matrix and filler 95/5, 90/10 and 85 / 15 (w/w) and glycerol as a plasticizer added as much as 3% of the volume plastic bottle waste on each ratio, and then it was processed using hotpress at 265 oC for 5 minutes. Results of testing the tensile strength properties indicate that plastic drinking bottle waste hybrid composite filled by rice husk -rice husk ash with the addition of glycerol in the ratio of 95/5 obtained maximum tensile strength of 2, 717 MPa, a Young's modulus value of 98 964 MPa, elongation at break of 2.603%. Results of SEM analysis on plastic drinking bottle waste hybrid composite filled by rice husk ash-rice husk with addition of glycerol in the ratio of 95/5 shows spread evenly on the surface of the filler matrix.
