ABSTRACT
This study focuses on the development and characterization of epoxy-based composites reinforced with three distinct types of fibers: carbon, kenaf, and flax. The materials was fabricated using hand lay-up technique, which involves the application of reinforced fibers layer by layer onto a mold until the desired thickness is attained. The reinforcement used in this project was epoxy resin. A fixed load was applied to the top of the laminates and left to cure for 24 hours at room temperature. Mechanical testing including tensile, flexural and impact tests was carried out to evaluate the performance of these composites. Water absorption test was carried out to gain insights into their moisture resistance properties. The results reveal that the carbon fiber reinforced epoxy composite stands out as the optimal choice for aerospace application. The composite displayed excellent mechanical properties, which include high strength (27.702 N/mm2) and high stiffness (2179.889 N/mm2). In addition, exceptional water resistance property was observed.
