Effect of the atmospheric plasma treatment parameters on jute fabric: The effect on mechanical properties of jute fabric/polyester composites

Abstract

The effect of atmospheric air plasma treatment of jute fabrics on the mechanical properties of jute fabric reinforced polyester composites was investigated. The jute fabrics were subjected to different plasma powers (60, 90, and 120 W) for the exposure times of 1, 3, and 6 min. The effects of plasma powers and exposure times on interlaminar shear strength, tensile strength, and flexural strength of polyester based composites were evaluated. The greatest ILSS increase was about 171% at plasma power of 120 W and exposure time of 6 min. It is inferred that atmospheric air plasma treatment improves the interfacial adhesion between the jute fiber and polyester. This result was also confirmed by scanning electron microscopy observations of the fractured surfaces of the composites. The greatest tensile strength and flexural strength values were determined at 120 W for 1 min and at 60 W for 3 min, respectively. Moreover, it can be said that atmospheric air plasma treatment of jute fibers at longer exposure times (6 min) made a detrimental effect on tensile and flexural properties of jute-reinforced polyester composites.

Oxygen plasma treatment of bamboo fibers (BF) and its effects on the static and dynamic mechanical properties of BF-unsaturated polyester composites

“…The air plasma was more efficient than the Ar plasma in terms of the ILSS of the resulting flax F-UPE composites (Bozaci et al 2013). The ILSS, tensile strength, and flexural strength of jute F-UPE composites were increased significantly by air plasma treatment (Demir et al 2011). The plasma treatment with glow discharged He increased the ILSS of jute F-UPE composites (Kafi et al 2012).…”

Characterization of Atmospheric Pressure Plasma Treated Polyester Fabrics

“…Cold plasma treatments enable the researchers to tailor the surface properties like adhesion, wettability or biocompatibility of numerous polymers by its specific applications [4][5][6] . The surface changes can be done both physically and chemically in textile fibers with the help of many synchronized processes such as activation, cross-linking, etching and grafting of chemical functional groups, which can be achieved with low-pressure plasma treatments [7][8][9][10] . Four major effects such as cleaning effect, generation of free radicals, increased micro roughness and plasma polymerization can be gained with the aid of plasma treatments based on the treatment conditions and the requirements for the processing of the materials.…”

Surface modification of aramid fibers via ammonia‐plasma treatment

“…In contrast, reactive gases such as oxygen and ammonia can incorporate oxygen‐ or nitrogen‐containing groups. These surface modifications may lead to changes in properties such as adhesion …”

“…These surface modifications may lead to changes in properties such as adhesion. [28][29][30] The aim of our article was to improve the surface properties of aramid fibers III (aramid fiber III is a new type of aramid fibers manufactured in China in recent years, which is one of the synthetic fibers with high strength and modulus of elasticity fabricated from aromatic polyamides and copolyamides 31 ) using ammonia-plasma treatment and obtain the optimum treatment parameters. Moreover, the effects of the significant process parameters, including treatment time, power and discharge pressure, were studied.…”
