The invention discloses a honeycomb sandwich plate design and manufacturing method, relates to the technical field of commercial spaceflight, and solves the technical problems of tedious process, long manufacturing period and high production cost of a honeycomb sandwich structure in the pre-embedded cementing assembly manufacturing process in the prior art. The method comprises the following steps: forming a honeycomb sandwich structure without an embedded part, wherein the honeycomb sandwich structure comprises an upper skin, a lower skin and a honeycomb sandwich fixed between the upper skin and the lower skin; forming a plurality of blind-hole-shaped enveloping holes in the honeycomb sandwich structure; assembling a rear embedded part; and carrying out glue injection to complete curing. According to the method, the working procedures of cutting of the honeycomb sandwich, wrapping and assembling of the embedded part with polystyrene foam, assembling of a pressure equalizing plate, appearance correction and the like are omitted, many unnecessary tool molds are omitted in the manufacturing process, the manufacturing process is simplified, the method is suitable for manufacturing the honeycomb plate with a large number of embedded parts and a large scale, the manufacturing period is shortened, the production cost is reduced, and model product design requirements are met.
本发明公开一种蜂窝夹层板设计与制造方法,涉及商业航天技术领域,解决了相关技术中蜂窝夹层结构在预埋胶接装配制造流程中存在流程繁琐、制造周期长和生产成本高的技术问题。本方法包括进行无埋件的蜂窝夹层结构成型,蜂窝夹层结构包括上蒙皮、下蒙皮和固定于上蒙皮与下蒙皮之间的蜂窝夹芯;在蜂窝夹层结构上形成盲孔状的多个包络孔;进行后埋件装配;进行注胶完成固化。本方法省去了蜂窝夹芯的裁剪、预埋件包裹发泡胶和装配以及均压板装配、外形修正等工序,在制造时省去许多不必要的工装模具,简化制造流程,适合埋件数量大和规模大的蜂窝板的制造,有利于缩短制造周期和降低生产成本,满足型号产品设计需求。
