The present study focuses on examining how metal-organic frameworks (MOFs) influence the thermal and ablative characteristics of Acrylonitrile butadiene rubber (NBR) matrix-based heat shielding material. Particularly, MIL-88 (MOFs) were synthesized, followed by their incorporation into NBR composite materials. Characterization tools that involved Xray
diffraction (XRD), Scan electron microscope (SEM), Fourier-transform Infrared spectroscopy (FTIR), and Thermogravimetric analysis (TGA) were utilized as techniques to analyze the properties of both the MOFs and NBR composite materials. Mechanical tests, thermal conductivity measurements, and ablative performance evaluations were carried out to study how the introduction of MOF influences composites mechanical strength, thermal properties, and ablative resistance. The results show that adding MIL-88 enhances the thermal resistance of NBR composite materials thus contributing to the formation of a dense char layer with increased graphitization during combustion. This structure layer is an efficient barrier to heat and mass transfer, enhancing ablative resistance for thermal insulation materials.
