Utilization of Polyethylene (PE) Plastic Waste as a Composite Matrix with Glass Fiber Amplifier Material

Introduction

The increasing amount of plastic waste, particularly polyethylene (PE), has become a serious environmental concern that requires immediate attention. The production and disposal of plastic waste have severe consequences on the environment, including pollution, climate change, and harm to wildlife. In this context, the development of innovative solutions to utilize plastic waste is essential. This study explores the potential of using PE waste as a composite matrix with glass fiber as a reinforcing material, aiming to find the optimal composition that produces a composite with the best strength and durability.

Background

Polyethylene (PE) is a widely used plastic material in various industries, including packaging, construction, and automotive. However, the disposal of PE waste has become a significant problem, with millions of tons of plastic waste ending up in landfills and oceans every year. The use of PE waste as a composite matrix with glass fiber offers a promising solution to this problem. Glass fiber is a common reinforcing material used in composite materials, known for its high strength, stiffness, and resistance to corrosion.

Methodology

The process of making composite begins with mixing PE waste and glass fiber with various weight ratios (W/W) of 90:10, 80:20, 70:30, 60:40, and 50:50 (%). The mixture is then pressed using a hot-press engine to produce a composite material. To determine the optimal ratio, an analysis of tensile strength and extension on the resulting composite is conducted. The results show that the ratio of 60:40 (PE: glass fiber) produces a maximum tensile strength of 2.48 kgf/mm2 and an extension of 56.6%.

Optimization of Composite Ratio

The next step is the addition of xylene as a wetting agent to the composite with an optimal ratio (60:40) with a variation of 5%, 10%, 15%, 20%, and 25% concentration. The resulting composite is then analyzed by tensile strength tests, extension, thermal analysis (DTA), and surface analysis (SEM). The results show that the addition of 20% xylene produces a maximum tensile force of 3.82 kgf/mm2 and an extension of 58.78%.

Thermal Analysis (DTA)

Thermal analysis (DTA) is conducted to determine the thermal conductivity of the composite material. The results show that the addition of glass fibers and xylene increases the thermal composite conductivity. This indicates that the composite material has improved thermal properties, making it suitable for applications where thermal resistance is required.

Surface Analysis (SEM)

Surface analysis (SEM) is conducted to examine the surface changes in the specimen before and after the addition of xylene. The results show that the addition of xylene makes the composite surface smoother than before the addition. This indicates that the addition of xylene improves the surface quality of the composite material.

Conclusion

This study demonstrates that PE waste can be processed into a powered composite with good strength and resistance through the addition of glass and xylene fibers as wetting agents. The results open up new opportunities in the use of plastic waste and encourage efforts towards a more environmentally friendly solution. By increasing composite strength and resistance, the potential for composite applications from this PE waste can be expanded, for example, in the construction, automotive, and electronic industries. Further research can be focused on optimizing the process of making composite and more diverse application development.

Future Directions

The use of PE waste as a composite matrix with glass fiber offers a promising solution to the plastic waste problem. However, there are several challenges that need to be addressed, including the optimization of the composite ratio, the development of new wetting agents, and the improvement of the surface quality of the composite material. Further research is needed to overcome these challenges and to develop more efficient and cost-effective methods for producing composite materials from PE waste.
