Abstract : Many lightweight materials are required to improve many advancements such as the travel distance of vehicles. Composites are required to be light, strong and if possible, economical so it may be used to increase the lightweight properties of vehicles and other lightweight applications. Indonesia has a variety of natural fibers such as rice straw and Ijuk palm fibers that are abundant and relatively cheap. This study aims to understand the character of the fibers when utilized in composites. Comp
