Abstract
Bio-based composites are reinforced polymeric materials, which include one or two bio-based components. Biocomposites have recently attracted great attention for applications ranging from home appliances to the automotive industry. The outstanding advantages are low cost, biodegradability, lightness, availability, and solving environmental problems. In recent days, biodegradable natural fibers are attracting a great deal of interest from researchers to work on and develop a new type of composite material for diverse applications. The objective of this work is to evaluate fire resistance and mechanical properties of epoxy polymer composites reinforced with lychee peel (Vietnam), at 10 wt%, 20 wt%, and 30 wt% mass%. The study showed that the mechanical properties and flame retardancy tended to increase in the presence of lychee peel reinforcement. In the combined ratios, 20 wt% lychee rind gave a limiting oxygen index of 21.5%, with a burning rate of 23.45 mm/min. In terms of mechanical strength, in which the Izod impact strength increased by 26.46%, the compressive strength increased by 25.20% and the tensile strength increased by 20.62%. The microscopic images (SEM images) show that the particle distribution is quite good and the adhesion and wetting compatibility on the two-phase interface of lychee peel-epoxy resin are strong.

It was observed that when the sample was destroyed, the additive particles partially protruded from the surface and on the contact interface between the additive and the epoxy resin matrix, no cracks were found. at shows that the bonding on the surface of phase division between epoxy resin-additives is very good

Summary
The world is facing a lot of problems related to waste management. organic recycling waste or rational use of waste is a primary concern. E organic waste includes kitchen waste such as vegetable peels, fruits, leaves, eggshells, green stalks, and vegetables in a chopped state. Many of these have biodegradable properties [1]. E study of mechanical properties of fiber-reinforced composites is of great interest to many scientists. Biodegradable organic wastes such as lemon peels, onion peels, and potato and carrot peels have recently been studied to make environmentally friendly, biodegradable composites. Green composites were developed using various fillers such as the outermost peel of a lemon [1], onion, potato, and carrot [2], and cellulose and silk fibroin [3] have recently been studied for their production of environmentally friendly, biodegradable composite materials. Parbin et al evaluated the mechanical properties of natural fiber-reinforced epoxy composites, concluding that fibers of natural origin such as plant fiber and animal fiber have very
