The invention relates to a self-adaptive biomimetic composite propeller blade. The body of the self-adaptive biomimetic composite propeller blade is formed by a guiding edge part and a following edge part. The self-adaptive biomimetic composite propeller blade is characterized in that the guiding edge part is arranged by taking the reference axis of a propeller as a center and provided with a rigid blade core, the rigid blade core is covered by a flexible material layer, and the flexible material layer extends along the chord length direction to form the following edge part. The self-adaptive biomimetic composite propeller blade has a simple and compact structure and is convenient to install. Due to the adoption of the self-adaptive biomimetic composite propeller blade, the overall manufacturing cost of the ship is reduced. Due to the adoption of the rigid blade core of the guiding edge part and the flexible material structure of the following edge part as well as the structure and the appearance of the prope
