The Growing Problem of Plastic Waste and the Need for Innovative Solutions

Plastic waste, particularly that derived from polyethylene terephthalate (PET), has become a significant environmental concern. The increasing production and disposal of plastic waste have led to severe environmental problems, including pollution, climate change, and harm to wildlife. However, recent research has shown that PET plastic waste can be utilized in an innovative way, reducing waste and creating materials with better physical characteristics.

The Concept of Composite Materials and Their Potential Applications

Composite materials are made from two or more distinct materials that are combined to produce a material with improved properties. In this study, PET plastic waste is used as a composite matrix, and fiber glass is added as a reinforcement material. The use of fiber glass serves to increase the mechanical strength of the composite produced, making it ideal for applications in various fields, including construction and automotive.

The Importance of Mixture Ratio and Wet Agent in Composite Production

The mixture ratio between PET and fiber glass is crucial in determining the physical properties of the composite material. In this study, a dry mixing process was carried out with various mixed ratios, including 9:1, 8:2, 7:3, 6:4, and 5:5. The results showed that the ratio of 7:3 produced a maximum tensile force value of 5.53 kgf/mm² and strain of 12.53%. The addition of chlorphenol ortho as a wet agent also showed significant improvements in the physical properties of the composite. The best results were obtained with the addition of 4% chlorphenol ortho, which gave 7.33 kgf/mm² tensile strength and 15.87% strain.

Thermal Analysis and Functional Group Analysis

Thermal analysis using Differential Thermal Analysis (DTA) showed that the addition of fiber glass and ortho chlorfenol increased the thermal conductivity of the resulting composite. This is an important factor that can affect the application of material in environments that require thermal insulation properties. Functional group analysis using Fourier Transform Infrared Spectroscopy (FTIR) showed that the interaction between PET and fiber glass is a physical interaction, not a chemical one. This is important to understand because it can affect the way this composite is functioning and how it can be further processed in real applications.

Conclusion and Future Directions

This study shows great potential in creating materials that are environmentally friendly and high functioning. The combination of plastic waste and fiber glass not only provides solutions to reduce waste but also produces products that can be applied in various industries. Further research is needed to explore the use of this composite material on a larger scale and test its reliability in various conditions. With an innovative approach like this, we can contribute to sustainability and environmental protection.
