Abstract

This Bachelor Degree Project outlines the background of the project “Investigation on Fatigue Properties of Natural Composite Containing Coconut Coir Using DOE Method”. In the application of industries such as automobiles, aerospace, military applications, building and packaging, interest in bio-composites has grown rapidly through renewable, low cost, easy to decompose, and biodegradation, bio-composites are also growing in terms of basic research. Fatigue properties are among the most important aspects of the mechanical response of materials, and adequate fatigue resistance is essential for the practical application of structural materials. It is associated with accumulation of damage under the loading cycle which eventually leads to fracture. Therefore, this report aims to investigate the effects of matrix and weight reinforced on fatigue properties using DOE method. The research methodology in this project has been studied and identified. The testing process was performed on the stress test and the fatigue test on each of the 8 sample parameters. Each sample will be tested 3 times to obtain the average value of each sample. Samples with high PVA parameters showed greater fatigue strength compared to low PVA samples. This study is expected to assist manufacturers in producing better products in the packaging industry.
