Fan blade plate strip, fan blade spar cap and forming method

The invention discloses a fan blade plate strip, a fan blade spar cap and a forming method, the fan blade plate strip comprises a plate, the two ends of the plate are respectively provided with a chamfer, and the two chamfers are symmetrically arranged so as to prevent the ends of the plate from generating a stress concentration effect; at least two resin drainage layers which are arranged at intervals are laid in the width direction of the surface of the plate, and a resin drainage groove is formed between every two adjacent resin drainage layers. The non-directional resin is prevented from flowing to form a plate interlayer resin surrounding air cavity, resin pouring between the stacked plate layers is more sufficient, the resin drainage layers and the strength control layers are added to the upper surfaces of the plates, the interlayer bonding performance of the upper and lower adjacent plates is further improved, the scheme is easy to implement, and actual production operation is facilitated. 本发明公开了一种风机叶片
