Recycled polyester-cotton blended fiber/high density polyethylene (HDPE) composite boards were prepared by internal mixing and compression molding two-step process with maleic anhydride grafted ethylene polyethylene-octene elastomer (POE-g-MAH) as compatibilizer. Two kinds of recycled polyester-cotton blended fiber were used as reinforcing fibers, including polyester-cotton long fiber (F 1 ) and polyester-cotton short fiber (F 2 ). Microstructure and properties of the composite boards reinforced with F 1 and F 2 were characterized by SEM and electronic universal tensile testing machine. The results showed that the comprehensive mechanical properties of polyester-cotton blended long fiber composite boards (F 1 HC 4 ) and polyester-cotton blended short fiber composite boards (F 2 HC 4 ) were optimal with a compatibilizer content of 4%. F 1 had a significant effect on the mechanical properties of the composite boards in two kinds of fiber with the same addition of compatibilizer. The tensile strength, flexural strength, impact strength and of F 1 HC 4 were 56.4%, 36.4% and 87.5% higher than that of F 2 HC 4 , respectively.
