In recent years, with the propaganda and promotion of the Olympic Games, the acceptance of rowing is increasing, the use of carbon fiber preparation for rowing oars has been recognized by athletes and business enthusiasts, and the rowing oar industry has been developing rapidly. In the future, with the gradual reduction of cost under domestic substitution, the application of carbon fiber in the oar industry will develop in two directions: high strength and lightweight. In this paper, T700 grade PAN-based carbon fiber racing oars with the carbon content of 20%, 50%, 80% and 100% were prepared by hot press moulding method. The technical indicators of the oars such as size, weight, deflection, stem type, blade and edge type, angle and handle were discussed and it was found that with the increase of carbon content, the weight of the oars decreased and the lightweight effect of carbon fiber was verified. It is also found that the carbon fiber content is directly proportional to the strength of the oar, with the deflection of the oar shaft decreasing and the strength increasing as the carbon content increases. The paper also introduces different types of racing oar blades, which are recommended to be optimally matched to the athlete’s body factor due to the different resistance generated by the different types of blades during the stroke.
