The invention relates to the technical field of helicopter rotor arms, and discloses a rotor arm and a glass fiber laying method of the rotor arm. Comprising a blade body, the paddle body comprises a front edge laying layer, a middle laying layer and a tail end laying layer, and the front edge laying layer, the middle laying layer and the tail end laying layer comprise outer reinforcing layers and inner reinforcing layers. The paddle is divided into three areas, and synchronous laying operation can be performed on different areas at the same time, so that the laying efficiency of the paddle is improved, the laying time is shortened, the laying operations of the multiple areas do not interfere with one another, the laying effect of the paddle is improved, and the laying efficiency of the paddle is improved. According to the stacking type laying method, a plurality of glass fiber layers which are mutually stacked in advance can be laid during laying work, so that the laying process of the plurality of layers of
