The invention belongs to the technical field of vibration isolation, and particularly relates to an integrated carbon fiber composite material damping filling sandwich structure raft frame and a preparation method. The raft frame comprises two supporting plates and a support arranged between the two supporting plates. The supporting plate comprises an upper panel and a lower panel; the metal honeycomb interlayer is provided with a plurality of filling holes and is arranged between the upper panel and the lower panel; the surface of the whole supporting plate is made of the carbon fiber composite material, damping of the raft frame is increased, the middle layer is provided with the metal material, the rigidity of the raft frame is increased, and the damping effect of the raft frame is improved. Meanwhile, the filling holes of the metal honeycomb interlayer are filled with the damping material filling blocks, so that the overall weight of the raft frame is reduced, the damping of the raft frame is further increased, and the problems that in the prior art, a metal raft frame is small in damping, and a pure carbon fiber material raft frame is insufficient in rigidity, large in weight and limited in vibration reduction effect are solved.
本发明属于隔振技术领域,具体涉及一种一体式碳纤维复合材料阻尼填充夹层结构筏架及制备方法。本发明的筏架包括两支撑板和设置在两支撑板之间的支座;支撑板包括:上面板和下面板;具有若干填充孔的金属蜂窝夹层,设置在上面板和下面板之间;与填充孔形状一致的若干阻尼材料填充块,阻尼材料填充块填充在金属蜂窝夹层的填充孔内,本发明整个支撑板的表面采用碳纤维复合材料,增加筏架的阻尼,中间层设置金属材料增加筏架的刚度,同时将阻尼材料填充块填充到金属蜂窝夹层的填充孔中,即降低了筏架的整体重量,又进一步地增加了筏架的阻尼,解决了现有技术中金属筏架阻尼小、纯碳纤维材料筏架刚度不足、重量大、减振效果受限的问题。
