| Abstract: | Taking raw ramie and Alkali treated raw ramie as reinforced material, KH550 as coupling agent, themechanical properties of ramie fiber reinforced unsaturated polyester resin composite materials is prepared. The effects of coupling agent dosage and fiber content on the mechanical properties of ramie reinforced unsaturated polyester composite materials are studied. The fracture surface of composite materials is analyzed by SEM. The experiment results show that the mechanical properties of composite materials is improved. The tensile strength and bending strength of raw ramie reinforced unsaturated polyester resin composite materials are 132. 6MPa and 364. 6MPa. The tensile strength and bending strength of Alkali treated ramie reinforced unsaturated polyester resin composite materials are 116. 5MPa and 297.7MPa. |
