Abstract

The development of the industrial world today causes the need for materials to increase, especially for a product. The use of metal materials in various product components is decreasing. This is caused by the heavy components made of metal, the forming process is relatively difficult, can experience corrosion and high production costs, therefore many other materials have been developed which have properties that match the characteristics of the desired metal material. One of the most developed materials today is composites. Utilization of natural fiber (banana frond fiber) as a composite fiber reinforcement material will have a very important meaning, namely in the field of utilization of banana plant waste in Indonesia which has not been sufficiently optimized from the economic field and the utilization of processed products. So from these considerations a study was conducted to obtain an analysis of the bending strength of banana fiber composites with a ratio of 3% fiber: 97% resin, 5% fiber and 95% resin, 7% fiber and 93 resin using unidirectional variations. Bending test using composite specimens in accordance with ASTM D790 size standards. Bending test among the 3 specimens, specimen A or 7% fiber had the highest yield among the third fiber, namely 14,201 kgf because of the large number of fibers used, while specimen C or 3% fiber had a lower yield, namely 6,684 kgf among the three fibers because less fiber used.
