The invention relates to the technical field of honeycomb structures, in particular to a basalt fiber cotton honeycomb core, a honeycomb structure and a filling method of the basalt fiber cotton honeycomb core. And basalt fiber cotton is filled in the honeycomb core body. The filling method comprises the following steps: dehydrating and drying the basalt fiber cotton; injecting liquid tert-butyl alcohol into the dewatered and dried basalt fiber cotton to enable the basalt fiber cotton to be condensed and solidified; cutting the cured basalt fiber cotton into regular hexagonal columns which are consistent with the honeycomb core in inner cavity size, core height and arrangement direction; the honeycomb core body is filled with the regular hexagon column shape, and the regular hexagon column shape is attached to an inner cavity of the honeycomb core body; and performing vacuum freeze drying on the honeycomb core body filled with the basalt fiber cotton to obtain the basalt fiber cotton honeycomb structure. The basalt fiber cotton honeycomb core body, the honeycomb structure and the filling method of the basalt fiber cotton honeycomb core body and the honeycomb structure aim at solving the problems that an existing silencing honeycomb is poor in mechanical structure strength and corrosion resistance and insufficient in low-frequency noise reduction capacity.
本发明涉及蜂窝结构技术领域,具体涉及一种玄武岩纤维棉蜂窝芯体、蜂窝结构及其填充方法。蜂窝芯体内填充有玄武岩纤维棉。其填充方法包括步骤:对玄武岩纤维棉进行脱水干燥处理;向脱水干燥后的玄武岩纤维棉内注入液态叔丁醇,使其凝结固化;将固化完成的玄武岩纤维棉切割成与蜂窝芯体的内腔尺寸、芯体高度、排布方向一致的正六边形柱状;将正六边形柱状填充进蜂窝芯体,且与蜂窝芯体的内腔贴合;对填充有玄武岩纤维棉的蜂窝芯体进行真空冷冻干燥,获得玄武岩纤维棉蜂窝结构。该武岩纤维棉蜂窝芯体、蜂窝结构及其填充方法的目的是解决现有消音蜂窝的力学结构强度及抗腐蚀性能较差、低频降噪能力不足的问题。
