Embodiment Construction

[0016] The method for attaching a decorative layer to a composite material board of the present invention will be further described in detail below in conjunction with specific embodiments.

[0017] When pasting the aramid paper honeycomb panel decorative layer on the composite material board (in this embodiment, the composite material board is a composite material honeycomb board), at first on the surface of the formed composite material honeycomb board that needs to be pasted with the decorative layer, brush evenly The configured glue, the glue used in this embodiment is the 1357L glue of 3M Company in the United States. After the glue is cooled for 30 minutes, the aramid paper honeycomb panel decoration layer is laid on the surface of the glue, and silicon The rubber film wraps the composite material honeycomb panel pasted with the decorative layer of the aramid paper honeycomb panel, and then evacuates to a vacuum degree of 0.09KPa or lower, so that the silicone rubber film...

Abstract

The invention relates to a method for pasting a decoration layer on a composite material plate. The method comprises the following steps: uniformly brushing a glue solution on the surface of a moldedcomposite material plate; airing the glue solution for a predetermined time, and pasting the decoration layer on the glue solution brushed surface of the composite material plate; wrapping the decoration layer pasted composite material plate with a rubber membrane, and performing vacuumizing to make the rubber membrane cling to the composite material plate; and releasing the vacuum pressure afterkeeping the vacuum state for a predetermined time, and removing the rubber membrane. The method can realize the complete pasting of the composite material plate and the surface decoration layer to make the composite material plate have a flat and beautiful surface. Additionally, the method can shorten the time for pasting the decoration layer on the composite material plate and reduce the unevenness of the manual rolling strength of personnel, and also has the advantages of convenience in enforcement, extensive applicability and low cost.

Description

technical field [0001] The invention belongs to the field of aircraft composite material manufacturing, and relates to a method for pasting a decorative layer on a composite material board. Background technique [0002] Generally, the decorative layer of composite material parts is pasted manually, and the curved surface parts are pasted by vacuuming with abrasive tools. When using these methods to paste the decorative layer, it is prone to uneven force on the surface, which leads to the incomplete release of the volatile components in the glue solution. As a result, the volatile components in the glue solution lift up the decorative layer after pasting, and bubbles appear on the surface, which affects the composite. The surface of the material board is smooth and beautiful. Contents of the invention [0003] In order to solve the existing technology when pasting the decorative layer on the composite material board, uneven force on the surface is prone to occur, resulting...
