The invention relates to the technical field of bearingless rotor wing flexible beam preparation, and particularly provides a composite material flexible beam and a preparation method thereof.The composite material flexible beam comprises a propeller hub connecting section, a propeller blade connecting section and a transition section, and the transition section comprises a rubber body, a carbon fiber plate and a glass fiber plate; centrifugal force is borne through the rubber body, the carbon fiber plate and the glass fiber plate, and flapping rigidity, shimmy rigidity and torsional rigidity are provided; a preparation method of the transition section comprises the following steps: S1, prefabricating two carbon fiber plates which are symmetrical up and down; S2, putting the two carbon fiber plates into an integrated vulcanization forming mold, adding a rubber material between the carbon fiber plates, and closing the mold, heating and vulcanizing to obtain a rubber sandwich carbon fiber plate structure; s3, a lower glass fiber board is prepared, specifically, the rubber sandwich carbon fiber board structure is placed on the lower glass fiber board, and then an upper glass fiber board is prepared; and S4, mold closing, heating and cooling are conducted, and the composite material flexible beam is obtained. The flexible beam is low in forming difficulty, high in product percent of pass and long in service life.

    本发明涉及无轴承旋翼柔性梁制备技术领域,具体提供了一种复合材料柔性梁及其制备方法,复合材料柔性梁包括桨毂连接段、桨叶连接段和过渡段,过渡段包括橡胶体、碳纤维板和玻璃纤维板;通过橡胶体、碳纤维板和玻璃纤维板承载离心力、提供挥舞刚度、摆振刚度及扭转刚度;过渡段的制备方法如下:S1:预制两块上下对称的碳纤维板S2:将两块碳纤维板放入一体硫化成型模具中并在碳纤维板之间加入橡胶材料,合模加热硫化得到橡胶夹芯碳纤维板结构;S3:制备下玻璃纤维板,将橡胶夹芯碳纤维板结构放置于下玻璃纤维板上,再制备上玻璃纤维板;S4:合模加热后冷却,得到复合材料柔性梁。本发明的柔性梁成型难度低,产品合格率高,使用寿命长。
