Stab And Puncture Resistance Of Knitted Aramid Fabric Literature Reviews Example

In the Journal of Advanced Materials submission by (Flambard and Polo, 2002) on the stab resistance of the multi-layers, an in-depth comparison was made between the Para-aramid and PBO fibres. The comparison based on the performance of the PPT and the PBO fibres. The experiment was conducted extensively on the stab resistance bench, and the results were recorded at each and every step and then analysed. The solution that was arrived on about the various pointed edges of the test weapons that were used in the experiment were all meant to simulate the effect of the extent of such edges on the aramid. Para-aramid material in stopping the edges and the blades. The textile structure was tested thoroughly, and all the results of these experiments were recorded by the authors.
Termonia (2006) investigated puncture resistance of the fabric towards needles. In his detailed study, he developed a pioneer scholarly and very comprehensive model that looked in the factors that control the fibre fabrics. The results out of the experiments were on a set of four distinct stages. The contact pressure, the slippage, the friction of the fabric and the slippage of the conical part of the fabric are all the stages that the experiment was taken through.
Khondker et. al (2006) dealt with the impact resistance and tolerance of composite material from E-glass fabrics. In the study they investigated three different styles of weft-nit structures that include Milano, plain knit and 1x1 rib. It was realized that both the changes to the structural parameters and the knit styles affected the tolerance and resistance of composites. A knitted structure with a higher value of loop density incorporated the best knit mesh generation, increasing the structural integrity impacting damage resistance and tolerance.
Decker et al. (2007) have extensively studied the stab resistance of the shear thickening fluid (STF)-treated fabrics just like the aramid fabrics. The technology has had dramatic improvements in the way spike threats can be avoided. In their study, it is evident that the effect of architecture in fabrics technology indicates their need of proposing the best ways in which stab and puncture resistance and the relevant processes to implement the same.
The knitted agamid fabric is a material that is stab and punctures resistance and for that reason it is very vital in the automotive industry. Its ability to be able to rest puncture and cuts is commonly enhanced by impregnating with thermoplastic and weaving it under what is a quasi-static testing condition, dynamically. Prior studies on the same have shown that the technology that weaves the fabric in a thermo-plastic material improves the stab and puncture resistance ability and important in reducing windowing (Mayo, J., et al, 2009). Further, they do note that the best and most appropriate way to make the fabric resistant is by utilizing the polyethene, and specifically Surlyn. The two are co-extruded in the films of varied thicknesses and which get laminated into the fabrics, all at equal weights and layers count.
The armour materials that are utilized in making the body armour have their role in offering protection against threats that are ballistic in nature (Tavanai et al. 2009). The efforts to make use of the technology much better and cross-cutting is what has been the driving force for this technology of making use of knitted fabrics with TP impregnation. The technology has that one step higher twist of being so strong and resistant to ballistic and another type of threats but after all is put right, and then it is concealed.
The aramid is single faced, and it is warped, an attribute that makes it so much better in terms of being able to be exact and resistant in protecting and in stab resistance. The experiment that was carried out by (Alpyildiz et al. 2010) shows that the knitted agamid does both fairly well against both the puncture and cut (the categories of stab threats). The reason an aramid fabric is knitted to protect against these types of threats is solely for its ability to be able to conceal and secondly, the ability to neutralize both types of stab threats, substantially.
Kim H. and Nam I. (2011) notes that all attributes of aramid fabric make it resistant to stab have to be investigated so as to lay the foundation for better ways to make it better with technology. The yarn slippage of the knitted fabric was taken to be a thermally stimulated process, and this way, the length of the most strained segment were used to calculate the strength of the strain values.
The knitted agamid, as noted by (Miao, 2014), becomes more usable when it is integrated by an ultra-high molecular and a more weighted type of polyethylene. The polyethene is single faced, and it is warped, an attribute that makes it so much better in terms of being able to be exact and resistant in protecting and in stab resistance. The experiment was similar to that carried out by (Alpyildiz et al. 2010) showing that the knitted agamid does both fairly well against both the puncture and cut (the categories of stab threats). The reason an agamid fabric is knitted to protect against these types of threats is solely for its ability to be able to conceal and secondly, the ability to neutralize both types of stab threats, substantially.
