Coconut fiber has numerous advantages in the industrial domain, particularly in the production of automobile dashboards, and other materials utilized in civil engineering. The purpose of this work is to create sandwich panels for basic home walls using natural fiber composites. In these panels, coconut fiber serves as the outer layer, while multiplex functions as the core material. This study employs experimental approaches and analyzes laboratory test results. With a 40% volume fraction and fiber lengths between 10 mm and 20 mm, the panels demonstrated an average flexural strength of 46.38 MPa, showcasing the impact of these parameters on the panel's strength. Moreover, at the same 40% volume percentage, the panels showed an impact strength of 4.4 joules, indicating their resilience under sudden impacts. According to the measurements, the sandwich panels had a weight of 84.672 grams of coconut fiber, 2.9808 grams of catalyst, and 146.0592 grams of polyester resin. © 2024, IEICES/Kyushu University.
