The Effect of Rice Husk as Additive in Injection Molding Process

This study investigated the moldability and mechanical properties of bio-composite with rice husk as natural reinforcement. Natural materials that are abundant in nature can be used reinforcement for polymer materials. plastic were to obtain alternative an injection molding process. With husk, polypropylene, MAPP, four compositions made raw material The from this was observed through visualization product. by tensile strength impact test on result showed these could injected form ASTM D638-03 Type V D256-04 specimens. Visually, more material, darker product color. differences values decreased along increased content. All had roughly same value lower than except RH-5%. bio-composites polypropylene tended decline increase Scanning electron microscope (SEM) analyzes done fracture side specimen. Microscale voids rarely found adding bio-composite. On other hand, breakage pullout phenomenon found.
