Damage monitoring and online maintenance system for thermoplastic composite material structure

Abstract

Equipment light weight rapidly develops, and thermoplastic composite materials are more and more widely applied. However, the automation degree is low in the aspects of operation monitoring and maintenance of thermoplastic composite parts at present. Therefore, the invention provides a damage monitoring and online maintenance system for a thermoplastic composite material structure, and belongs to the technical field of new materials and intelligent manufacturing. Comprising a thermoplastic composite structure damage identification, positioning and evaluation subsystem, an acoustic emission sensor, a damage identification and evaluation system, a damage positioning system, a three-dimensional laser scanner, a thermoplastic composite structure damage area pretreatment subsystem, a thermoplastic composite structure damage area maintenance subsystem and the like. After the damage is identified and positioned, the 3D printing technology is used for repairing the damaged area, the problems that a traditional repairing method is time-consuming, low in efficiency, low in automation degree and the like can be solved, and the method can be applied to mining equipment, offshore platforms, airplanes and other equipment and is particularly suitable for repairing in toxic, harmful and dangerous environments.

Background technique [0002] Lightweighting is an effective way to save energy and reduce emissions. Therefore, aircraft, high-speed rail, automobiles, ships, mechanical equipment, etc. are vigorously carrying out lightweight design and engineering application work. Thermoplastic composite materials, especially fiber-reinforced thermoplastic composite materials, have the advantages of low density, high specific ...

AI Technical Summary

Problems solved by technology

However, at present, in terms of equipment operation monitoring and maintenance, the degree of automation is still low

The maintenance of production machinery, large-scale mining equipment, special transportation equipment, offshore platforms, etc. in the factory mainly relies on manual inspection and maintenance, which is time-consuming, inefficient, and slow in maintenance

In addition, there are some occasions and situations that are not suitable for traditional people to overhaul, such as: satellites in space, equipment working in toxic and harmful environments, etc.
