- Abstract
This paper aims to study the feasibility of implementing a new bio-composite with a sandwich structure made from date palm tree waste. This is done by valuing such waste, often left in palm groves and burned under most circumstances, which can be a vital resource at the lowest cost. This work has developed several sandwich-structured composite plates based on this waste. The skins are composite materials based on an epoxy matrix and palm tree fibers (Epoxy/Rachis fibers); the core was made of raw wood or a composite with petiole wood particles. After three-point mechanical bending tests, macroscopic analysis and SEM micrographs were used to determine what kind of damage the specimen had. Characterization tests on the new bio-composites showed good thermal properties; with a thermal conductivity below 1W/mK is between 0.0148W/mK and 0.0178W/mK. It is also characterized by its low volumetric mass, less than 1.2g/cm³. These properties make it a good thermal insulator, especially in environmentally friendly bio-construction areas making a sandwich-structured composite using palm tree waste is a very effective, environmentally friendly, and economically inexpensive option.
