Propeller and machine body

The invention relates to a propeller and a machine body. The propeller comprises forming foam, at least one first fiber fabric layer arranged on the upper surface of the forming foam and at least one second fiber fabric layer arranged on the lower surface of the forming foam, and the first fiber fabric layer and the second fiber fabric layer are both soaked with first gel. The forming foam of the propeller and forming foam of the machine body are made of foam which is light, can greatly reduce the weight of the propeller and the weight of the machine body and makes cruising ability of an unmanned aerial vehicle higher. Strength and toughness of the propeller can be improved due to the elastic characteristic of foam. The first fiber fabric layer and the second fiber fabric layer are both soaked with the first gel, the first gel makes the first fiber fabric layer and the second fiber fabric layer cured and hardened and formed more easily. 本发明涉及种螺旋桨和机身，包括成型泡沫、设置于所述成型泡沫上表面的至少层第纤维织物层、以及设置于所述成型泡沫下表面的至少层第二纤维织物层，所述第纤
