thermal barrier

• مادة أو طلاء يُستخدم لحماية الأسطح من درجات الحرارة العالية، ويُطبَّق عادةً في مجالات الطيران والسيارات والصناعة لتقليل انتقال الحرارة.

A material or coating used to protect surfaces from high temperatures, commonly applied in aerospace, automotive, and industrial contexts to reduce heat transfer.

1. Heat insulation layerC1formal

   A material or structure designed to prevent the transfer of heat, protecting against high temperatures.

   • The spacecraft's thermal barrier protects it during re-entry into the atmosphere.
   • Engineers installed a thermal barrier in the engine to improve efficiency.
   • The building's thermal barrier reduces energy loss in winter.

2. Temperature limit in physicsC2formal

   A theoretical or practical limit beyond which heat transfer becomes critical or damaging.

   الحد الحراري في الفيزياء

   • The thermal barrier of the material was tested under extreme conditions.
   • Exceeding the thermal barrier can cause structural failure.
   • Researchers are developing new composites to overcome the thermal barrier.
