Abstract
Composite is a combination of two or more materials arranged in a certain way to get new properties in a material results. For the manufacture of composite polyester fiber berpenguat pandanus thorns with rice husk powder filler is one way to get new material properties. This study aims to determine the absorption properties of sea water and impact toughness of fiber reinforced polyester composite with a tenon pandanus rice husk powder filler. Composite manufacture is done by hand lay-up method with random fiber direction. Materials used in the manufacture of these composites are fiber pandanus thorns with rice husk powder filler. Tests were carried out based on ASTM standard D5229 for water absorption testing and ASTM D256 for impact testing. The method used in the testing is a method charpy impact. To determine the significance of the effect of variations in fiber volume fraction and fiber length used three ways analysis of variance (ANOVA) with a variation of the fiber length of 10 mm, 20 mm and 30 mm. Variations in fiber volume fraction of 10%, 20% and 30% by long immersion in water absorption 30 days. Impact testing conducted after soaking 0, 7, 15, and 30 days. From the test results it can be concluded that the variations in the volume fraction, fiber length, and long soaking significant effect on sea water absorption value and impact toughness. In testing the water absorption weight gain values obtained the highest percentage of 25.07% on the fiber length of 20 mm with a fiber volume fraction of 30% and the lowest was 15:20% in volume fraction of 10% with a length of 10 mm. In testing the volume gain the highest percentage value obtained by 11:40% on the fiber length of 20 mm with a fiber volume fraction of 30% and the lowest rate of 4.66% on a volume fraction of 10% with a length of 30 mm. In testing the types of weight gain values obtained the highest percentage of 14.87% on fiber length of 10 mm with a fiber volume fraction of 30% and the lowest value of 9:21% in volume fraction of 10% with a length of 20 mm. While the value of the highest impact toughness at 10958.74 J / m2, obtained on fiber length of 30 mm with a fiber volume fraction of 30% and a soaking time of 30 days. And low impact toughness is equal to 1800.39 J / m2 obtained on fiber length of 10 mm with a fiber volume fraction of 10% and a soaking time of 0 days.
