Composite material square cabin wall plate metal embedded part embedding method

Abstract

The invention belongs to the technical field of composite material square cabins, and particularly discloses a composite material square cabin metal embedded part embedding method which comprises the steps that machining a metal embedded part into a design size, and cleaning the metal embedded part; cutting an aluminum honeycomb of which the size is the same as that of the metal embedded part; filling the aluminum honeycomb with a honeycomb filling glue, and forming grooves with the same length and width as the metal embedded part and the height being the sum of the height of the aluminum honeycomb and the height of the metal embedded part through cutting in a sandwich panel; placing the filled aluminum honeycomb in the groove with an adhesive film pasted inside; placing the metal embedded part on the aluminum honeycomb with the adhesive film attached to the surface; and laying an outer skin on the metal embedded part, and completing embedding of the metal embedded part. According to the invention, the bonding strength and fatigue resistance of a sandwich structure composite material are improved, and the bearing requirement of the embedded part is met, so that the service life of the sandwich structure composite material is prolonged.

Description

technical field [0001] The invention belongs to the field of composite material shelters, and relates to a method for embedding metal pre-embedded parts of composite material shelter walls. Background technique [0002] Composite shelters have been widely used in the automotive field due to their excellent properties such as high specific strength, high specific modulus, and good fatigue resistance. Composite material shelter panels are the main structure of composite material shelters. Generally, various mechanical equipment required for the shelter are installed on the shelter panels. Composite material shelter panels are generally sandwich structures, mainly composed of front and rear covers. Composed of skin and sandwich material, the skin is generally made of multi-layer carbon fiber prepreg or glass fiber prepreg, and the sandwich material mainly includes PU foam, PVC foam, aluminum honeycomb, aramid honeycomb, etc.; Bulkhead metal embedded parts are mainly used to in...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few studies on the design and embedding methods of metal embedded parts in composite material shelter panels. In the existing technology, the embedding method used is mainly to embed metal embedded parts when forming the skin and bonding embedded parts on the skin surface, but both methods have problems such as low bonding strength of metal embedded parts and low fatigue strength
