natural fiber for the construction of hybrid bio-composites. In the current research project, a thorough analysis of the use of soy-PF resin for the creation of composites reinforced with jute was conducted. A novel and practical cutlery material was created after the mechanical properties were evaluated and optimized. In order to study the value addition of these newly proposed biocomposite materials as an ecological alternative in terms of natural resources versus synthetic resources, variables such as hardness, cytotoxicity, and degrading qualities of composites were also explored.

In recent years, efforts have been made to produce advanced composite materials in order to lessen environmental impact and to extent sustainability. Traditional materials are largely substituted by composites due to their greater properties like flexural strength, low thermal expansion and high strength.

Two chemical treatments were applied to jute fibers to create a better bonding of fiber to resin in natural composite materials. The jute fibers have been treated with hydroxide potassium (KOH) and a bleaching agent, canxi hypochlorite (Ca(OCl)2.4H2O), in varying periods. Characterization techniques such as FT-IR, SEM were used to evaluate the effect of chemical treatments on fiber structure. After treatment the surface topography of jute was clean and microfibrils were revealed, these lead to an enhancement in mechanical properties and interfacial strength between jute fiber and PP.

The surface treatment by physical method of jute fiber using air plasma was investigated. Fiber was treated by the atmospheric plasma with various conditions of power 50W and different treatment times (from 1 min to 7 min). After treatment, the characteristics of fiber changed remarkably and fiber surface observed by SEM analyze showed a better morphology for adhesion. The result showed that tensile strength and Young’s modulus of jute fiber were slightly improved, however there was a remarkable improvement interface adhesion between fibers and polypropylene (PP) resin.
