The Effect of Jute Fiber Directional Orientation on the Physical and Mechanical Properties of Composite with Polyester Resins

Introduction

The increasing demand for sustainable and eco-friendly materials has led to the development of composite materials made from natural fibers, such as jute. Jute fiber, obtained from the basic material of burlap rope, is combined with polyester resin in a composition of 85% polyester resin and 15% jute fiber. This study aims to investigate the effect of jute fiber directional orientation on the physical and mechanical properties of composite boards with polyester resins.

Background

Jute fiber is a natural fiber with a unique combination of properties, including high tensile strength, low density, and excellent durability. The chemical composition of jute fiber consists of 71% cellulose, 13% lignin, 13% hemicellulose, 0.2% pectin, 2.3% of water-soluble substances, and 0.5% fat and wax. The elementary fiber length of jute fiber ranges from 1-5 mm, with an average of 2 mm, and the diameter varies between 20 μm to 25 μm, with an average of 23 μm.

Methodology

The composite boards were manufactured by combining jute fiber with polyester resin in a composition of 85% polyester resin and 15% jute fiber. The jute fiber angle orientation was varied at 0º, 30º, 45º, 60º, and 90º. The physical properties tested include density, water absorption, and porosity, followed by various mechanical tests, such as flexible strength testing, impact strength testing, and tensile strength testing.

Results

The test results show that the physical and mechanical properties of jute fiber composite have a density value between 1.22 gr/cm³ to 1.20 gr/cm³. The water absorption capacity ranges from 2.74% to 12.5%, while the porosity is within 3.33% to 15%. Flexible strength testing produces a value between 91.65 MPa to 14.7 MPa, the impact strength between 19.37 J/mm² to 9.05 J/mm², and tensile strength ranges from 19.126 MPa to 3,069 MPa.

Discussion

The results of this study indicate that the physical and mechanical properties produced meet JIS A 5905: 2003 standards, which stated that the flexural strength must be greater than 32 MPa, density between 0.3 to 1.3 gr/cm³, and the water content is less than 25 %. This indicates that jute fiber composites with polyester resins can be used as potential materials in engineering applications, especially in vehicles such as car bumpers.

Additional Analysis and Explanation

Jute is one of the natural fibers that is increasingly popular as composite material. The advantages include sustainability and relatively low production costs. In this study, the variation of jute fiber angle orientation variations is very important because it can significantly affect the mechanical properties of composite. Placement of fiber at a certain angle allows a better load distribution, providing additional strength to composite.

From the test results, it appears that the greater the angle of fiber orientation, flexural strength tends to decrease. This can be explained by way of jute fiber interacting with the polyester resin matrix. At a smaller angle, the fiber can support the load received efficiently, whereas at a larger angle, the fiber angle can cause a decrease in bond strength between materials.

Conclusion

Utilization of jute-based composites and polyester resins not only has the potential to reduce production costs, but also provides environmentally friendly alternatives compared to conventional synthetic materials. In car development, the use of materials like this can reduce the total weight of vehicles, which in turn will have a positive impact on fuel efficiency.

Future Work

By looking at the results and analysis, further development of jute fiber composite has the potential to be applied in various fields, including the automotive industry, construction, and consumer products, thus strengthening the role of natural fibers in meeting sustainable material needs.
