Impact test is to measure the ability of a material to absorb the sudden application of a load with breaking [12]. The impact tests were carried out according to ASTM D 256-05 at room condition using a Universal Pendulum Impact System (Ray-Ran, UK). Figure 5 shows the results of the impact tests. The graph Figure 5 indicates that the impact strength of the composites decreases as the rice husk loading increases. The pure HDPE composite has the highest impact strength compared to the rice husk reinforced composites.
