Structural Analysis of Kevlar Fabric Treated with Oxygen Plasma

Numerical and Experimental Study of Ballistic Response of Kevlar Fabric and Kevlar/Epoxy Composite

Kevlar is a type of aramid fibers which is characterized by high strength to low weight ratio. This material is widely used in bulletproof vests and helmets, in which it creates a barrier to projectiles to protect specific objectives, laminated tubes and pressure vessels, etc. In this study the ballistic behavior of Kevlar /epoxy composite and Kevlar fabric is investigated. The results showed t...

Antimicrobial Property of Plasma Treated Bamboo Fabric Imparted with Combinatorial Herbal Extract

The present study focused on DC air plasma exposed on bamboo fabric finished with antimicrobial agents. The knitted bamboo fabrics were exposed to plasma treatment at optimized conditions to increase the hydrophilicity. The changes in the hydrophilic properties, chemical and physical modification of the plasma treated fabric were studied using the AATCC 79, FTIR and FESEM respectively. The comb...

Evaluation of Thin Kevlar-epoxy Fabric Panels Subjected to Shear Loading

The results of an analytical and experimental investigation of 4-ply Kevlar-49-epoxy panels loaded by in-plane shear are presented. Approximately onehalf of the panels are thin-core sandwich panels and the other panels are solid-laminate panels. Selected panels were impacted with an aluminum sphere at a velocity of either 150 or 220 ft/sec. The strength of panels impacted at 150 ft/sec was not ...

Characterization of Structural Changes in Thermally Enhanced Kevlar-29 Fiber

Dyeing of Cotton Fabric with Natural Dyes Improved by Mordants and Plasma Treatment

Nowadays, there is a great tendency for eco-dyeing and finishing of textiles with natural products. several natural dyes have been used for dyeing of protein fibers but a low number have the ability to dye cotton fiber because of low affinity of cellulose to the natural dyes. In this study madder and weld natural colorants were used to dye cotton fabric premordanted with three metallic salt...
