Before being processed into composites, reinforcement fabrics may undergo repeated involuntary deformation, the complete sequence of which is here referred to as specimen history. To mimic its effect, fabric specimens were subjected to sequences of defined shear operations. For single fabric layers with unconstrained thickness, quantitative evaluation of photographic image data indicated that r...

In this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. Fabrics are impregnated with Shear Thickening Fluid (STF). The effects of the (STF) have been considered as frictional effect. The STF has been made (Nano Silica and Polyethylene Glycol (PEG)) and then diluted by ethanol proportion of 3:1. Yarn pulling out test from in...

Currently, technical fabrics play a major role in many industries due to their multiple characteristics. The aim of this research was utilize composite knitted bars reinforce concrete beams. Six cord-knitted samples with two different polypropylene yarn counts (outer layer) and three core materials were manufactured immersed local epoxy material (Kemapoxy 150). Composite prepared way. Several t...

The Indian textile industry has a major impact on the world economy through millenniums. At present all the textile industries aim to produce competitive fabrics. The competition depends mainly on productivity and quality of the fabrics produced by industry. In the textile sector, there are huge losses due to faulty fabrics. Fault identification in the manufactured fabric is the most complicate...

Textile composites are widely used in automotive, naval, and aerospace industries. The variation of the topology of the textile structure will affect the performance of the composite. The yarn micro-geometry is determined by 1) the textile process, such as weaving, braiding, etc. and 2) the composite forming process, such as vacuum bagging, resin transfer molding, etc. In this paper, we present...

Textile fabrics are highly anisotropic, so that their mechanical properties including strengths are a function of direction. An extreme case is when a woven fabric sample is cut in such a way where the bias angle and hence the tension loading direction is around 45° relative to the principal directions. Then, once loaded, no yarn in the sample is held at both ends, so the yarns have to build up...

Usually, a fabric weave pattern is recognized using methods which identify the warp floats and weft floats. Although these methods perform well for uniform or repetitive weave patterns, in the case of complex weave patterns, these methods become computationally complex and the classification error rates are comparatively higher. Furthermore, the fault-tolerance (invariance) and stability (selec...
