摘　　要：文章为了探究2.5D结构筒状立体机织物的细观几何关系,通过显微观察和结构分析,提出纬纱截面为双凸透镜截面、经纱截面为扇形截面的假设,并建立了2.5D结构筒状立体机织物实体模型和2.5D结构细观几何结构模型,推导了细观几何表达式和细观微元中纤维体积分数计算公式。结果表明2.5D结构被用于筒状织物时,细观几何结构会发生一些改变。In order to explore the meso-geometry of the tubular woven fabric with 2.5D structure, lenticular cross section of weft and sector cross section of warp were assumed by means of the micro- graph observation and analysis of fabric structure. The solid model Of 2.5D structure tubular woven fabric and the meso-geometry model with 2.5D structure and was established. Meso geometric expres- sion and calculation formula of fiber volume fraction in a micro-unit was also derived. The results show that when the 2.5D structure is used in the tubular fabric, some changes have occurred in the meso-geometry structure.
