Q: Will Inner Bulletproof Vest fail in extremely cold or hot environments?
A: Extreme environments pose severe challenges to their performance:
1. Extreme Cold (e.g., -40°C):
• Material embrittlement: Especially for ceramics, toughness decreases, resistance to repeated impacts may weaken, and they become more prone to cracking.
• Adhesive failure: The bonds between the layers may become brittle.
• Solution: Use materials certified for low-temperature operation (such as certain polyethylene panels) and conduct rigorous low-temperature testing.
2. Extreme Heat/Fire Environments:
• UHMWPE (Polyethylene): Melting point approximately 145°C, it softens and fails rapidly in a fire.
• Aramid: Good heat resistance, but will carbonize and decompose upon prolonged exposure to open flames.
• Key Lesson: Bulletproof vests are not fireproof clothing. In vehicle fires or building fires, it is essential to prioritize removing external protective gear for rapid evacuation.
