DRY RICE HUSK FILLER EFFECT TO TENSILE BEHAVIORS OF RECYCLED HIGH-DENSITY POLYETHYLENE (HDPE)-BASED GREEN COMPOSITES

The possibility of using plastic waste to manufacture hybrid bio-composite materials with the dry husk of Asian rice (Oryza sativa L.) is investigated. The most polluted and unsustainable plastic waste is High-Density Polyethylene (HDPE) due to its single-use, which decreases in quality if it is reused is selected. The mixtures chosen are local natural fiber and easy to find, potentially a preliminary study of a composites building material. Furthermore, to improve the tensile properties of this hybrid bio-composite material, an additional organic filler is used, such as rice husk (Oryza sativa L.) in a combination of 10%, 12%, and 15%. Samples for this study were processed using the hot press methods based on ASTM D882. Tested for tensile strength, modulus young, yield stress, and elongation is carried out to see an increase in the performance of the biocomposite material. The test results show that the best tensile properties are samples with 12% rice husk, resulting in excellent sample compatibility proofed by Scan Electron Microscopy to study bio-morphological composites. This project has shown that the composites based on natural fiber will be potential building materials due to their improved tensile properties.
