Abstract
mpact resistance is one of the main consideration in measuring service life, liability and safety of polymer composite structures or products. Impact resistance of a composite material can be measured in terms of energy absorption, depth of penetration and total impact time. In this study, the influence of alumina Al2O3 on impact properties of short glass fiber reinforced polymer was investigated. The drop weight impact tests were performed in accordance to ASTM D7136 standard using Dynatup impact tester. Based on the results, the incorporation of micronsize alumina filler enhanced the energy absorbed during crushing, reduced the depth of penetration of the impactor and expanded the total impact time hence improved the impact properties of the composites.
