Abstract

This research aims to analyze the effect of fiber type on the impact value and physical properties of composite materials with an Unsaturated Polymer Resin (UPR) matrix. Composite materials are materials that consist of two or more components with different physical and chemical properties, which when combined produce materials with superior properties. In this research, the types of fiber used were pineapple leaf fiber, sea pandan fiber, and palm palm fiber. Experimental methods are used to measure the impact values and physical properties of various types of composites made. Impact value testing was carried out using the Charpy method, while the physical properties analyzed included density and water absorption. Test results show that the addition of pineapple leaf fiber to the biocomposite has a positive impact, namely increasing the impact strength and physical value. The test results showed that the highest impact strength and physical values occurred in pineapple leaf fiber. The absorption energy value is 0.3756 Joules and the impact strength value is 8.339 kJ/m2. The physical properties were tested with a density value of 1.165 g/cm3, absorption of 1.422%, and expansion of 0.899%. The results of this research indicate that the type of fiber used has a significant influence on the impact value and physical properties of the composite. These findings indicate that choosing the right type of fiber in composite materials can improve the mechanical and physical performance of the material, so that it can be applied in various industrial fields such as automotive, aerospace and construction. This research makes an important contribution to the development of more efficient and environmentally friendly composite materials. Keywords: Pineapple Leaf Fiber, Sea Pandan Fiber, Palm Palm Fiber
