Experimental Investigation on the Bending Behavior of Weft Interlaced Multilayered Woven Fabrics for Composite Applications

Direct preforming processes have potential for fiber-reinforced semi-finished products, creating 3D structures with strong delamination resistance using double-flat-steel-healds. However, the shedding method limits pattern variety, necessitating alternative options for interlacing diversity. One approach is using weft yarn instead of warp yarn for interlacing. This study explores its impact on mechanical properties, focusing on bending behavior, fiber volume content, and micrograph analysis of infiltrated warp and weft interlaced structures. The result shows interesting differences in mechanical behavior regarding different weave types and test direction as well as communalities within the individual structures.
