Problems solved by technology

In order to increase the anti-corrosion performance of metal parts, fiber composite materials are used to form anti-corrosion layers on the surface of metal parts. However, the compatibility and bonding performance of fiber composite materials and metal parts are poor, especially for strip, tubular and other structures. Due to The thermal stress is different, and the fiber composite material is more likely to be delaminated with the metal material to cause shedding, which affects the service life of the metal parts, and subsequent maintenance is frequent, requiring a lot of manpower and material resources to solve

Abstract

The invention relates to a metal and composite material anti-corrosion combination structure component and a manufacture method thereof. The metal and composite material anti-corrosion combination structure component comprises a metal pipe body, multiple metal bumps, a transition layer and a fiber composite material layer, wherein the multiple metal bumps are arrayed on the outer surface of the metal pipe body at intervals; the transition layer is formed by winding a fiber thread which is mixed with polymer resin annularly on the metal pipe body, wherein each metal bump is accommodated in the transition layer; and the fiber composite material layer is stacked on a polymer waterproof layer. The metal and composite material anti-corrosion combination structure component has a long service life.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a corrosion-resistant composite structural part of metal and composite material and a preparation method thereof. Background technique [0002] Offshore floating bodies can create artificial islands on the sea that are similar to the working environment on land, expanding the space for human survival, activities and work at sea. Super-large offshore floating bodies are the basic equipment for the development and utilization of marine resources, which can meet the needs of effective use of ocean space and establishment of sea military bases. [0003] However, the conditions in most of China's sea areas are harsh, especially in the South China Sea, where the temperature is high and the corrosion of metal parts is serious, especially some metal parts near the waterline. In order to increase the anti-corrosion performance of metal parts, fiber composite materials are used...
