Abstract

Abstract: Plain woven composites are widely used in aviation, aerospace, automobile, ship and other fields because of their advantages of high strength, stable performance and simple structure. As a reinforced structure of composite materials, the geometric characteristics of plain fabric have an important effect on the structural properties. As a kind of flexible structure, the geometry of plain fabric yarns is easy to deform significantly under the influence of technological parameters. For glass fiber plain fabric, four kinds of composite material samples were prepared by four kinds of pressure. The internal yarn structure of four samples was scanned by micro-CT. In this paper, the digital element method is used to model the meso-scale of plain fabric, and the compacting simulation under four kinds of pressure is carried out. The results of Micro-CT scan were compared with the simulated yarn shape to verify the correctness of the simulation method and further analyze the yarn shape change process under pressure load.

Key words: Micro-CT technology, digital unit method, flow compaction, yarn pattern, composites
