The invention belongs to the technical field of paddle structures of cross-medium aircraft rotors, and particularly relates to an impact-resistant paddle composite material structure. Comprising a surface anti-impact coating, a skin, a spanwise bearing girder, frame girder surface carbon cloth, frame girders, transverse reinforcing ribs, spanwise reinforcing ribs and filling foam, the frame girder surface carbon cloth is pasted on the surfaces of the frame girders, the spanwise reinforcing ribs are of a semi-I-shaped structure, the transverse reinforcing ribs are made of carbon cloth and are of a shape like a Chinese character'ri ', and the filling foam is filled into the spanwise reinforcing ribs. The upper and lower surfaces of the transverse reinforcing rib are adhered to the skin, the left side of the transverse reinforcing rib is adhered to the arc-shaped surface of the frame girder, the right side of the transverse reinforcing rib is adhered to the left side of the spanwise reinforcing rib, and a transverse reinforcing rib is formed in the middle of the transverse reinforcing rib; spanwise bearing girders are arranged between the frame girders and the skin; foam is filled in the transverse reinforcing ribs and between the spanwise reinforcing ribs and the skin, and the surface impact-resistant coating covers the outer surface of the whole blade.
