Abstract

The development of composite materials is increasingly rapid to obtain alternative materials that meet the criteria, namely the material is strong, light, cheap and easy to obtain. In this study, banana fiber and iron sand were chosen because of their abundance in Indonesia, so they are easy to obtain. The specimens were made using the hand layup method with woven fiber grooves, polyester resin was used as a specimen matrix, specimen testing used charpy impact testing to determine strength, hardness, and ductility. The purpose of the study was to find out the best composition of the variations of the specimens made. experimental method was used with a ratio of four weight variations (0%, 20%, 30%, 40%). In specimens with a weight fraction of 0% the value of absorption energy (0.961 J/mm2) and impact values ​​(0.0080 J/mm2), the highest value for the 10% weight fraction was sample A (0.0043 J/mm2) and the highest value was in sample A (0.0043 J/mm2). The lowest value was in the B fraction (0.004 J/mm2), the 20% weight fraction specimen, the highest value was in the B sample (0.0033 J/mm2) and the lowest value was in the A and C samples (0.0025 J/mm2), the heavy fraction specimen 30% of the highest value is in sample B (0.0025 J/mm2) and the lowest value is in samples A and C (0.0019 J/mm2), of the four weight variations the highest value of impact testing results is 10% fiber volume with a value of 0 .0043 J/mm2 and the lowest value is 100% fiber volume with a value of 0.0012 J/mm2

Abstract

Composite is a material formed from a combination of two or more constituent materials through homogeneous mixing. Where the mechanical properties of each of the constituent materials are different. Composite material is also a very important material because it has special properties, these properties include its stiffness, strength, non-corrosion and fatigue life which is better than other conventional materials. The purpose of this study is to determine the mechanical characteristics of Composite materials. bamboo fiber and iron sand on weight variations, the best mechanical properties characteristics of several variations and determine voids or bubbles in the resin. The process of making this bamboo fiber Composite material uses volume variations of bamboo fiber by 15%, 25% and 35% then followed by printing the material on the astm d369-90 tensile test mold. In the tensile testing process, the highest mechanical properties were found in the High variation with a tensile strength value of 2.70 kgf/mm2, and a strain of 0.51% of the initial size. While the lowest mechanical properties are found in the Low variation with a tensile strength value of 2.16 kgf/mm2 and a strain of 0.33% of the initial size.
