Abstract

This study aims to determine the bending strength of a sandwich composite material with a polyester skin reinforced with fiberglass and banana stem fiber with the coreParaserianthes falcataria wood. The skin was made by hand lay up method, with a volume fraction of 10% glass fiber and a banana stem fiber volume fraction of 10%, 20% and 30%. The sandwich composite was made by gluing skin and sengon marine wood core composites. The test carried out is the bending strength test with ASTM C393 standards.The test results showed that the highest average bending strength of 53.81 MPa was obtained in sandwich composites with polyester skin with a volume fraction of 10% glass fiber and 30% banana stem fiber, while the lowest average bending strength of 41.43 MPa was obtained at 10% glass fiber sandwich composite and 10% addition of banana stem fiber. So it can be concluded that the addition of volume fraction of banana stem fiber has an effect on the bending strength of the sandwich composite material.
