Abstract

Lightweight is an important measure for energy conservation, emission reduction and environmental protection, engineering plastics and composite materials belong to typical lightweight materials and have the advantages of small density, high specific strength and specific modulus, corrosion resistance and the like, and more and more plastic and composite material parts exist in equipment. Detection and maintenance of equipment are one important aspect of intelligent manufacturing, but the development level is far behind the intelligent manufacturing of production equipment, and technologies related to equipment maintenance need to be vigorously developed. The invention relates to a damage monitoring and online maintenance system for a plastic and composite material structure, which can be used for carrying out damage identification, evaluation, positioning and repair on plastic and composite material parts in equipment such as transportation equipment, mining equipment and an offshore platform, and is particularly suitable for situations such as toxic, harmful and dangerous environments which are not suitable for human operation. The system has the advantages of high applicability, high intelligent degree, low cost and the like, logistics supply and storage pressure can be greatly reduced, and development of an intelligent manufacturing industry is promoted.

Description

technical field [0001] The invention relates to a real-time measurement, evaluation, positioning and online maintenance system for damage to plastic and composite material parts in aerospace equipment, mechanical equipment, large-scale vehicle transportation equipment, special chemical equipment, special equipment, etc., especially to a plastic and The invention relates to a damage monitoring and online maintenance system of a composite material structure, which belongs to the technical field of new materials and intelligent manufacturing. Background technique [0002] Lightweight is one of the important measures for energy saving, emission reduction and environmental protection, and has become the development strategy of the national manufacturing industry. At present, aircraft, high-speed rail, automobiles, ships, and mechanical equipment are vigorously carrying out lightweight design and engineering applications. Engineering plastics and composite materials are typical l...
