Heat shielding refers to materials or structures designed to protect objects from extreme heat. This is crucial in various applications, such as spacecraft, where vehicles like the Space Shuttle experience intense temperatures during re-entry into the Earth's atmosphere. Heat shields absorb, reflect, or dissipate heat to prevent damage to sensitive components. Common materials used for heat shielding include ceramics, metals, and specialized coatings. These materials are engineered to withstand high temperatures while maintaining structural integrity. Effective heat shielding ensures the safety and functionality of equipment in high-heat environments, such as in aerospace, automotive, and industrial processes.
