Impact and Thermal Properties of Unsaturated Polyester (UPR) Composites Filled With Empty Fruit Bunch Palm Oil (EFBPO) and Cellulose
MetadataShow full item record
In this research, the impact properties of unsaturated polyester (UPR) composites filled with empty fruit bunch palm oil (EFBPO) and cellulose are investigated. The composites were made by hand-lay up method by mixing UPR with the content of each fillers (EFBPO and cellulose) of 5,10,15,20 wt.%. The parameter which was carried out on the prepared samples was impact test. It was found that the addition of fillers to the matrix caused the impact strength of composites increased at 10% addition of EFBPO and 5% addition of cellulose. The results are confirmed by fourier transform infra-red (FTIR) and supported by thermogravimetric analysis (TGA) and scanning electron microscopy (SEM).
