A strain monitoring two-dimensional wound composite underwater vehicle shell and its preparation method

Abstract

The invention discloses a strain monitoring two-dimensional winding composite material underwater vehicle shell and a preparation method thereof. The underwater vehicle shell comprises three parts from inside to outside: a metal sealing layer, a rigid strength layer and a corrosion-resistant layer, wherein the rigid strength layer is prepared by adopting a plurality of carbon fiber mixing and combination modes on the surface of the metal sealing layer, so that the underwater vehicle shell can adapt to different complicated underwater environments; the corrosion-resistant layer is prepared from chopped fiber reinforced resin matrix composite materials, so that the surface not only has the characteristic of resisting seawater corrosion, but also achieves the purpose of promoting the binding strength through the reinforcement action of the chopped fibers so as to effectively guarantee the service life. Through the embedding use of optical fibers or strain gauges or other different forms of strain inductors in the structure of the two-dimensional winding composite material rigid strength layer, the small strain of the whole shell structure or structure inner layer under high external pressure condition can be effectively perceived, and the real-time monitoring on the service status change of the underwater vehicle shell can be achieved.

Description

technical field [0001] The invention belongs to the technical field of underwater equipment, and relates to a shell structure for an underwater vehicle, in particular to an underwater vehicle shell made of multi-layer two-dimensional winding composite material and equipped with multiple intelligent monitoring functions. Background technique [0002] An underwater vehicle is an underwater intelligent machine device that carries a variety of electronic equipment and energy, and can be intelligently controlled by a computer and navigate autonomously. It can be used for submarine engineering work in the fields of underwater exploration and deep sea exploration. [0003] Traditional underwater vehicles use a sealed structure to ensure the pressure difference between the interior and exterior of the cabin in the seabed environment, so metal navigation equipment needs to be prepared with a certain thickness. While the metal thickness increases, the weight of the underwater vehicle ...

AI Technical Summary

Problems solved by technology

While the metal thickness increases, the weight of the underwater vehicle increases, which leads to a reduction in the number of equipment carried, which will seriously affect the functions and endurance of the navigation equipment, and the increase in the weight will also affect the performance of the underwater vehicle. heading control
