Exfoliated Sodium Montmorillonite Reinforced Elastomeric Nanocomposites: Ablation, Thermal Transport/Decomposition/Transitions and Mechanical Aspects)

Sadia Sagar Iqbal, Nadeem Iqbal, Tahir Jamil, and Arshad Bashir
Abstract—The performedresearch is used to explore the prospectiveinfluence of sodium montmorillonite (Na-MMT) on the high temperature ablation, thermal stability/conductivity and mechanical parameters of elastomeric composites. Ablation characteristics viz. (backface temperature rise, insulation index, and ablation rates)were amassed using oxy-acetylene flame test. Thermal conductivity, thermal stability, ultimate tensile strength and elastomeric hardness were performed on domestically developed TC apparatus according ASTM E1225-99, TGA, UTM, and rubber hardness meter, respectively. The experimental data explored that with increasing Na-MMT contents in the acrylonitrile butadiene rubber, back-face temperature acclivity, linear ablation resistance, and radial ablation impedance were reduced by a factor of 95, 800, and 88%, correspondingly. Maximum filler content viz. 30% has efficiently improves thermal insulation character, tensile properties and elastomeric hardness of the fabricated specimens. Microscopic results showed microporosity generation during ablation that eventually enhanced the insulation character of the ablative specimens at high temperatures. In the view of the obtained results, well dispersed Na-MMT in NBR matrix is a good combination of high as well as low temperature insulation applications.

Index Terms—Aerospace, polymer composite, oxy-acetylene flame, ablation testing, thermal analysis, mechanical properties, thermal conductivity, electron microscopy.
