This project investigates the thermal behavior of a composite silica aerogel subjected to extreme temperature cycling conditions simulating the space environment. Silica aerogels are widely recognized for their exceptional thermal insulation properties and ultralight weight, making them suitable for space missions. However, their performance under repeated thermal stress remains a critical research area. The simulation involves a rectangular sample of silica aerogel exposed to alternating boundary temperatures of +150°C and –150°C to replicate orbital day-night cycles. Using SimScale’s thermal analysis capabilities, this model computes the transient temperature distribution across the material and identifies thermal gradients that may contribute to material fatigue and performance degradation. Material properties are based on experimentally validated data from recent studies on composite-reinforced aerogels. The results will be used to evaluate the aerogel's thermal resilience and to support entropy-based modeling of degradation behavior. Objectives: To simulate the temperature distribution in silica aerogel under cyclic space-like conditions. To evaluate heat flux and thermal gradients during each cycle. To generate reference plots and data for integration with entropy-based analytical models in the main research.
