Problems solved by technology

In the known technology, the embedded metal parts in the composite material connection structure usually only undergo simple surface treatment such as dust removal and oil removal, resulting in the combination between the metal part and the composite material matrix resin becoming the weakest part in the embedded metal connection structure. It is often unable to bear a large load, and the safety is low when used

Abstract

The invention discloses a manufacturing method of a continuous fiber reinforced composite material connecting structure, and relates to the field of material performance treatment. The connecting structure comprises a metal part and a composite material, wherein the metal part is pre-buried in the composite material, and the composite material is solidified and formed to be combined with the metalpart. According to the method, the surface of the metal part is subjected to surface oxygen permeation treatment, so that the surface roughness of the metal part is increased, the bonding strength ofthe composite material and the metal part is improved, and then the bearing capacity of the overall structure of the composite material is improved.

Description

technical field [0001] The invention relates to the field of material performance processing, in particular to a method for manufacturing a connection structure of continuous fiber reinforced composite materials. Background technique [0002] Due to their excellent performance, continuous fiber reinforced composites have been widely used in fields including aviation, aerospace, transportation, energy, etc., and have gradually developed from non-load-bearing structures to secondary load-bearing structures and even primary load-bearing structures. As the main load-bearing structural part, in order to realize the connection with other components and ensure the ability to carry large loads, it is often necessary to pre-embed metal parts in composite materials. In the known technology, the embedded metal parts in the composite material connection structure usually only undergo simple surface treatment such as dust removal and degreasing, resulting in the combination between the m...
