Honeycomb sandwich layer structure and preparation method thereof

The invention discloses a honeycomb sandwich layer structure and a preparation method thereof. The preparation method comprises the following steps of coating the upper surface and the lower surface respectively of a honeycomb core material with a layer of sticking substances; coating the upper surface and the lower surface of the honeycomb core material coated with the sticking substances with alayer of prepreg respectively; vacuumizing the honeycomb core material coated with the prepreg and curing the honeycomb core material coated with the prepreg under an atmospheric pressure to obtain the pretreated honeycomb core material; vacuumizing the pretreated honeycomb core material and curing the pretreated honeycomb core material to make the pretreated honeycomb core material shape up so asto obtain the honeycomb sandwich layer structure. The honeycomb sandwich layer structure is low in cost, and can prevent collapse of honeycomb materials. 本发明公开了种蜂窝夹层结构及其制备方法，该制备方法包括：在蜂窝芯材上表面和下表面分别铺覆层粘接物；在铺覆了粘接物的蜂窝芯材上表面和下表面分别铺
