Abstract

The invention belongs to the technical field of preparation of composite materials, and relates to a preparation method of a water soluble phenolic resin honeycomb core material for preparing a sandwich structured composite material. A five-step treatment process of gluing and pressing, stretching and shaping, gumming and curing, flame retardance and slicing is performed for a plant fiber paper in sequence; compared with traditional meta-position aramid fiber paper honeycombs, the process of preparing the honeycomb core material by the method is environment-friendly, free of the solvent volatilization, low in harm to human bodies and free of the explosion risk; and the prepared honeycomb core material has equivalent performances to the traditional meta-position aramid fiber paper honeycomb core materials, is higher in cost performance, and can be applied to such fields as aircraft interiors and rail transit.

Description

technical field

[0001] The invention belongs to the technical field of composite material preparation, and relates to a method for preparing a water-soluble phenolic resin honeycomb core material, which is used for preparing sandwich structure composite materials. Background technique

[0002] Honeycomb core materials for resin-based sandwich structure composite materials mainly include aluminum honeycomb core materials, aramid paper honeycomb core materials and glass cloth honeycomb core materials. It is formed by laminating and gluing, and it can also be printed on the aluminum foil first, and manufactured by stretching. The cost of aluminum honeycomb is low, and it has been widely used in the early aerospace field. However, it was found in the process of use that the aluminum honeycomb is very prone to electrochemical corrosion after being combined with the composite material panel, and the wave transmission performance is poor. Replaced by aramid paper honeycomb. Arami...
