Abstract
With the increasing demand for lightweight and high-performance materials, the application of carbon fiber composite (CFRP) in the manufacture of pressure vessels has received extensive attention. Firstly, the paper introduces the high strength, light weight, corrosion resistance, low coefficient of thermal expansion and excellent thermal stability of carbon fiber composites, and how these properties make them ideal materials for pressure vessel manufacturing. In terms of application status, this paper reviews the research progress in the field of carbon fiber composite pressure vessels at home and abroad, and analyzes the types and structural designs of applied vessels in detail. The performance and potential of carbon fiber composites in actual pressure vessel manufacturing are demonstrated by case study. Aiming at the technical difficulties of carbon fiber composite manufacturing pressure vessels, the precise control of carbon fiber preformed parts, the optimization of interlayer bonding strength of composite materials, the influence of environmental factors on manufacturing process, and the challenges of gap and defect detection technology are deeply discussed. These difficulties are the key factors restricting the wide application of carbon fiber composite materials in pressure vessels. In order to improve the performance of composite pressure vessels, a series of strategies are proposed. Including the optimization of material formulation and composite processes, such as the optimization of carbon fiber types and proportions and the vectorized fiber arrangement design; Design reinforcement structures to improve vessel strength, such as reinforced circumferential fiber reinforcement designs and the use of prestressed structural reinforcement techniques; Improve quality control with advanced NDT technology, such as ultrasonic inspection technology and innovative practices of infrared thermal imaging inspection; And environmental adaptability research and implementation of protective measures, including the development and application of protective coatings and surface treatment technology.
