Abstract

The invention belongs to the technical field of composite manufacturing, and particularly relates to a checking structure for a composite honeycomb sandwich structure during secondary bonding. The checking structure comprises a supporting mold, a composite framework, a honeycomb core material, a plate-plate bonding area checking film, a plate-core bonding area checking film and a vacuum bag; the composite framework and the honeycomb core material are arranged in the supporting mold; the vacuum bag is installed on the supporting mold in a sealed mode to form a vacuum area, and a plate-plate bonding area and a plate-core bonding area are located in the vacuum area; the plate-plate bonding area is located on the upper portion of the composite framework, and the plate-core bonding area is located on the upper portion of the honeycomb core material; the plate-plate bonding area checking film is located in the plate-plate bonding area, and the plate-core bonding area checking film is locatedin the plate-core bonding area; the checking precision in the secondary bonding process of the honeycomb sandwich structure is improved, and multiple surfaces are checked at the same time.

Description

technical field [0001] The invention specifically relates to the technical field of composite material manufacturing, in particular to a verification structure used for secondary adhesive bonding of a composite material honeycomb sandwich structure. Background technique [0002] Honeycomb sandwich structure composite is the most material-saving and has the largest strength-to-weight ratio structural material known so far. Compared with the solid material, the effective material used by the honeycomb sandwich structure composite material is only 1%-5% of the replaced material. It is obviously a lightweight material with great potential and low material consumption and low energy consumption. The honeycomb sandwich structure is usually formed by bonding relatively thin panels and relatively thick cores. Generally, the panels are made of materials with relatively high strength and rigidity, and the core is made of materials with relatively low density. The sandwich structure ...
