Agro-wastes are by products of agricultural products such as husk, straw, cobs of fiber. Areca nut fiber is one of the natural fiber alternative materials in composite making scientifically. The recycled plastic polyethylene is one of the adhesive used in composite production. So that this can overcome environmental problems, and also do not endanger health. In this research the single-layer experimental composites were prepared from (40, 60, 80, 100, 120.g) betel nut fiber (BNF) and 60.g recycled plastic polyethylene by compressing molding process. The properties of prepared composites including modulus of rupture (MOR), impact strength, hardness, density, water absorption (WA), swelling thickness (ST) and moisture content (MC) were determined by British Standard (BS), Indian Standard (IS) and American Society for Testing Materials (ASTM) methods. The surface morphologies of composite boards were studied by digital microscope (China). The results obtained were compared with FAO (2013) and JSA (2003) standards. From the observation of overall results, composite CB1 (PE 60: BNF 40g) had the best quality grade of 621.16 kgcm-2 (MOR), 49.80 kjm-2 (impact strength), 95.50 Shore D (hardness), 0.87 gcm-3 (density), 8.93% (WA), 6.67% (ST) and 3.69% (MC) which had fulfilled to the standards. According to the result of this research, it can be concluded that the controlling of fiber content is the one of the important factors for composite production.
