In the prior art, coating is usually used to glue the sizing end surface of the honeycomb core material. However, in the production process of this kind of component, due to the high viscosity of the silicone rubber glue, it is difficult to apply glue. The amount of glue is not easy to control, and it is prone to uneven gluing
In addition, when the honeycomb core material composed of multiple hexagonal lattice structures is glued to the flexible composite material, the effective bonding surface is the gridded end face of the multiple hexagonal lattices of the honeycomb core material, and the multiple hexagonal lattices Compared with the surface area of the overall honeycomb core material, the area of the glued end surface composed of the end surface is very small. If the glue is applied to the flexible butt joint surface as a whole, there will be a lot of adhesives that belong to invalid bonding, which cannot meet the requirements.

Abstract
The invention relates to a gluing method for a honeycomb core material of a spacecraft, which comprises the following steps: S1, adding a diluent into an adhesive, uniformly stirring to prepare an adhesive, and coating an operation plane with the adhesive; s2, according to the range of the preset sizing density d, the sizing amount range of the preset sizing amount m is obtained through calculation; s3, carrying out the lifting and weighing steps for multiple times until the weight of the gluing amount reaches a preset gluing amount range; the lifting and weighing step comprises the following steps: flatly immersing the sizing end surface of the honeycomb core material in the adhesive, lifting the honeycomb core material out of the adhesive, separating the sizing end surface from the adhesive, and weighing the honeycomb core material immersed with the adhesive. According to the sizing method, the sizing density can be controlled, the problem that the sizing end face of the honeycomb core material cannot be uniformly sized when the high-viscosity glue solution is used is effectively solved, the operation is simple and convenient, the sizing is uniform, and the sizing amount is controllable.
Description
technical field [0001] The invention belongs to the technical field of composite material structure forming, and in particular relates to a glue sizing method for spacecraft honeycomb core materials. Background technique [0002] A high-viscosity silicone rubber is used as a structural adhesive, and the honeycomb core material is glued to the back of a flexible composite material structure with a high-viscosity silicone rubber adhesive to form an important component of the spacecraft. In the prior art, coating is usually used to glue the sizing end surface of the honeycomb core material. However, in the production process of this kind of component, due to the high viscosity of the silicone rubber glue, it is difficult to glue, and it is difficult to apply glue. The amount of glue is not easy to control, and it is prone to uneven gluing. In addition, when the honeycomb core material composed of multiple hexagonal lattice structures is glued to the flexible composite material...
