Abstract

The objective of this study is to determine the effect of pore type on energy absorption. The material used for this study is the blend of ENR and RR. The ratio is varied in order to produce different types of pore. Initially, ENR and RR are inserted into the internal mixing for compounding. The blend is crushed into small aggregates before hot compressed using hot press to form ENR/RR sheet. Then, foaming process is performed on the ENR/RR blend. Sample were perform under experiments in which, the experiment were conducted for this study is the ball drop test. The purpose of this experiment was to observe the effects of pore against energy absorption. With this test, it was observed that the pore reduce the impact. Each of these samples was conducted 3 times and done in accordance with the parameters of the resulting ratio. To get the size of the pore in the sample, an optical microscope was used and the pore can be clearly seen. The results of each experiment and were recorded in the optical microscope and draw conclusions about the study. The size of pore that produces shows different in every sample. Pore that have optimum size also produce more pore unit in volume show the energy absorption high compare to the other sample.
