Description
Textile composites are made by intimately combining two or more different substances each with its own characteristics. Since the physical and mechanical properties of the resultant products are superior to those of the original components, they have found many application fields such as aerospace, automobile, marine construction, sports, defense, and medicine. Textile composites made of 2D laminates show better stiffness and in-plane strength but lower out-of-plane resistance because of the absence of third dimension reinforcement. To overcome this demerit, 3D textile structures have been developed using different manufacturing techniques like weaving, knitting, and braiding etc. with technical improvements in them. Among them 3D weaving is extensively used for making most advanced forms of composites for hi-tech industries like aerospace and automobiles. However, the weaving machines used for making 3D fabrics are quite expensive. Because of this reason, such equipment could not be introduced in textile industry and textile composites manufacturing in Pakistan is negligible.
This research focuses on successfully developing the multilayer stitched fabrics ranging from four to ten layers on a hand loom using 1420 denier Kevlar® 49 multi-filament yarn. Such multilayer stitched fabrics can be produced on mechanical weaving machines with dobby attachment and the constructed structures can be used for making soft body armor or as reinforcement for high anti-ballistic composite materials.
