摘　　要：为优化管状三维机织物的设计,以三维机织物为管壁,并运用管状组织的构造方法,提出基于平织机的该类织物组织的设计方法和矩阵模型。首先以三维机织物为管壁得到表组织图,通过“底片翻转”法得到里组织图,按照分层织制的方法确定管状三维机织物组织图。通过MatLab函数对表组织矩阵元素置换及矩阵调序以获取里组织矩阵,并运用Kronecker积运算实现表、里组织矩阵按比例相互嵌入及表经提升点元素的赋值,从而得到管状三维组织矩阵。研究结果表明,提出的组织图设计方法及其矩阵模型可提高该类组织的设计效率。Objective Tubular composites are widely used in petrochemical,construction,aerospace and other fields.The traditional processing method is winding fiber or fabric and curing after resin impregnation.Because the interlayer is only bonded by resin,it is easy to cause delamination.If the tube wall is made of three-dimensional(3-D)woven fabric,the material′s ability to resist delamination would be enhanced.In order to improve the design efficiency based on normal looms,a design method and matrix model of 3-D tubular woven fabric are proposed on the basis of combining the weaving rules of tubular and 3-D woven fabrics.Method The weaving method of 3-D tubular woven fabric is"flattening-weaving-restoring".First,the weaving process takes the fabric as a two-layer 3-D woven fabriclinked at both selvedges,and then opened up to form a tubular section after removal from the loom.The weave diagram is divided into three steps.Firstly,the face weave diagram is obtained by selecting 3-D woven fabrics such as orthogonal,angle-interlocking and stitched multi-layer as the tube wall.Secondly,the back weave diagram is obtained by method called"negative and flip".Finally,according to the method of layered weaving,the weave diagram of 3-D tubular woven fabric is determined.Results To verify the feasibility of the proposed method,a design example on 3-D tubular woven fabric based on weft through-thickness type orthogonal weave is given(Fig.3).Firstly,the arrangement ratio of yarn is determine,for example,face warp∶back warp=1∶1,face weft∶back weft=1∶1,then number of warp and weft in a unit of 3-D tubular woven fabric R gj=12 and R gw=12.Secondly,the face weave(Fig.3(a))is entered at the intersection of odd columns and odd rows and the back weave(Fig.3(b))is input at the intersection of even columns and even row.Finally,according to the method of layered weaving,the intersection of the odd columns and even rows is indicated by""(Fig.3(c)).The example shows that the proposed method is feasible.Other examples,3-D tubular woven fa
