A process for increasing the bonding strength of aluminum honeycomb panels

Abstract

The invention discloses a process for increasing the bonding strength of an aluminum honeycomb panel. The aluminum honeycomb panel includes an upper panel, an aluminum honeycomb core and a lower panel sequentially laminated from top to bottom. The upper panel and the lower panel are connected with the aluminum honeycomb panel One side of the laminated core is coated with glue, including the following steps: (1) fixing the upper plate and the lower plate of the aluminum honeycomb panel after forming the billet; (2) moving the distance a of the aluminum honeycomb core to make the glue gather on the aluminum honeycomb core on the outer edge of the hole. This process makes the glue gather on the outer edge of the cells of the aluminum honeycomb core, thereby greatly increasing the contact area between the cells of the aluminum honeycomb core and the glue, thereby increasing the bonding strength between the aluminum honeycomb core and the upper and lower plates, and improving the aluminum honeycomb core. The bonding strength of the honeycomb panel can reduce the amount of glue on the premise of meeting the bonding strength requirements, thereby saving costs.

Description

technical field [0001] The invention relates to the technical field of composite panels, in particular to a process for increasing the bonding strength of aluminum honeycomb panels. Background technique [0002] Aluminum honeycomb panel refers to a composite panel with a three-layer structure of "aluminum panel / aluminum honeycomb core / aluminum panel". The aluminum panel and aluminum honeycomb core are bonded with an adhesive. This composite panel has high strength, light weight and no formaldehyde. It is widely used in the interior and exterior decoration of large buildings, as well as the compartment partitions of aircraft or ships, and is now further expanded to the fields of furniture panels and other fields. In the production process of existing aluminum honeycomb panels, glue is usually used to coat the side of the aluminum panel in contact with the aluminum honeycomb core, so that the two aluminum panels are laminated and bonded to the upper and lower ends of the alumi...

AI Technical Summary

Problems solved by technology

In the production process of existing aluminum honeycomb panels, glue is usually used to coat the side of the aluminum panel in contact with the aluminum honeycomb core, so that the two aluminum panels are laminated and bonded to the upper and lower ends of the aluminum honeycomb core respectively. However, this method The contact area between the cells at the root of the aluminum honeycomb core and the glue on the aluminum plate is relatively small, and the bonding strength between the two is not high. The role of aluminum plate connection
