An impact-resistant polyester material is provided, which includes a polyester resin matrix material, a toughening agent and a compatibilizing agent. The toughening agent and the compatibilizing agent are dispersed in the polyester resin matrix material. The toughening agent is a polyolefin elastomer (POE). The compatibilizing agent is configured to assist in improving compatibility between the toughening agent and the polyester resin matrix material. The compatibilizing agent is at least one of a polyolefin elastomer grafted with glycidyl methacrylate (POE-g-GMA) and a polyolefin elastomer grafted with maleic anhydride (POE-g-MAH). The compatibilizing agent is configured to assist the toughening agent to be dispersed into the polyester resin matrix material with a particle size between 0.5 micrometers and 1.5 micrometers, so that the impact-resistant polyester material has an impact strength of not less than 20 kg-cm/cm.
