The thermal behavior of epoxy composites is crucial for understanding their performance under varying temperature conditions, especially in applications such as structural materials, electronics, and coatings. Epoxy composites are often reinforced with fillers like agrowaste materials, which offer benefits such as improved thermal conductivity, reduced thermal expansion, and enhanced sustainability.
Investigation of Thermal Behavior of Epoxy Composites Filled with Agrowaste Materials:
Thermal Conductivity:Effect of Agrowaste Fillers: Agrowaste materials like rice husk, coconut shell, and agricultural residues can improve the thermal conductivity of epoxy composites. The nature and particle size of the agrowaste filler play a significant role in the thermal properties. Fillers with higher specific surface areas typically improve thermal conductivity.

Thermal Expansion:Effect of Agrowaste Fillers: The addition of agrowaste fillers can reduce the coefficient of thermal expansion (CTE) of epoxy composites, which is beneficial for applications where dimensional stability is critical, such as in electronic components or automotive parts.

Thermal Degradation:Effect of Agrowaste Fillers: The thermal degradation behavior of epoxy composites is influenced by the type and concentration of agrowaste fillers. Some agrowaste materials, like coconut shell powder, provide a higher degradation temperature due to their inherent carbon content, which can improve the material's resistance to thermal damage.

Thermal Stability:Effect of Agrowaste Fillers: Epoxy composites filled with agrowaste materials can exhibit improved thermal stability compared to unfilled epoxy. The presence of these fillers can help in enhancing the material's resistance to high temperatures, reducing the rate of weight loss during thermal cycling. References:T. S. Srinivas and P. R.

Conclusion:Summary: Agrowaste materials are an effective, sustainable reinforcement option for improving the thermal properties of epoxy composites. Their impact on thermal conductivity, expansion, degradation, and stability depends on factors like filler type, particle size, and loading level. Overall, agrowaste-filled epoxy composites are promising materials for thermal management applications in a variety of industries, offering both environmental benefits and improved performance.
