The compression resistance of spacer fabric is a major advantage with respect to the performance and composite manufacturing process. The optimum compression performance of spacer fabrics varies according to the requirements of the application in question. This investigation focused on the prediction of the compression performance by two-scale (micro and macro) mechanical analysis using the Finite Element Method (FEM). Micromechanical analysis of the unit cell of the spacer layer was conducted for the calculation of its compression resistance. The apparent mechanical properties of the outer layers were also evaluated by micromechanical modelling. The respective properties of the outer and spacer layers are introduced in the macromechanical model of the sample for analysis of the complex deformation during simulation of the compression test, thus realising the second stage of modelling. The computational method proposed is evaluated by comparison of the load - displacement curves resulting from the simulation and experimental data of compression. Moreover, the effect of the structural and physical parameters of the sample on the compression resistance was investigated.http://hdl.handle.net/123456789/28784ISI:00027260750001256517611230-3666engINST CHEMICAL FIBRESFIBRES & TEXTILES IN EASTERN EUROPEFinite Element Methodspacer fabriccompression resistanceNumerical Modelling of the Compressional Behaviour of Warp-knitted Spacer FabricsjournalArticle2009Δημοσίευση σε περιοδικόPublication in journal Κλωστοϋφαντουργικά προϊόνταTextilesisi - Materials Science, Textiles covers resources that focus on the manufacture of clothing and furniture from materials made of natural fibers (e.g., leather, cotton, wool, wood) and/or synthetic fibers (e.g., polyester, vinyl, nylon).
