Smart type autonomous underwater vehicle (AUV) shell structure and preparation method thereof

Abstract

The invention discloses a smart type autonomous underwater vehicle (AUV) shell structure and a preparation method thereof, belonging to the field of AUV shells. The smart type AUV shell structure sequentially comprises a metallic closed cavity, a rigid layer, a reinforcing layer and an impermeable layer, wherein the rigid layer is a multi-dimensional hybrid fiber reinforced resin-based composite material rigid layer; the rigid layer is formed by a hybrid fiber three-dimensional braided prefabricated fabric structure reinforced high-performance resin matrix; the three-dimensional braided prefabricated fabric structure of the rigid layer is mixed with optical fibers; a reinforcing layer is a two-dimensionally wound hybrid fiber reinforced resin-based composite material reinforcing layer; thereinforcing layer is arranged on the surface of the rigid layer in a two-dimensional winding manner; the impermeable layer is a multi-dimensional carbon fiber reinforced rubber-based impermeable layer; the impermeable layer is formed by compounding a carbon fiber three-dimensional woven fabric structure and high-strength rubber. The smart type AUV shell structure can monitor the stress state of an AUV shell in real time, and has better pressure resistance, impermeability, impact resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of AUV shell technology, in particular to a smart AUV shell structure and a preparation method thereof. Background technique [0002] Autonomous underwater vehicle (AUV) is a new generation of underwater vehicle, which has many advantages such as large range of activities, good maneuverability, safety and intelligence, and has become the main tool for completing various underwater detection tasks and research work. For example, in the civilian field, it can be used for important tasks such as underwater pipeline laying, seabed investigation, data collection, drilling support, seabed construction, and underwater equipment maintenance and repair; in the military field, it can be used for reconnaissance, laying mines, minesweeping, underwater rescue, and diving lifesaving. Wait. Since the underwater robot is not limited by the scope of the cable and has good concealment, it has become the focus of industrial and militar...

AI Technical Summary

Problems solved by technology

[0003] The mechanical stress requirements of the underwater environment are complex, and the requirements for the pressure resistance, leakage prevention, impact resistance and corrosion resistance of the entire equipment are very strict. Traditional underwater robot shell materials are made of metal materials with anti-rust coating on the surface. Although the overall airtightness of this composite structure is good, the long-term underwater operation has brought great challenges to the corrosion resistance of the metal. In addition, the weight of the metal itself is relatively large, which is not suitable for diving deep or deep. Underwater operations require complex working conditions. Due to the limitation of self-weight and space of the equipment or components carried by oneself, the complexity of the work is bound to be limited.

[0004] In addition, the forming method of the traditional metal material itself determines that the shell material itself has almost no response measures to the change of the underwater force state, and this is what the development of modern intelligent materials cannot match.
