Summary
New lightweight thermoset-based composite material that combines fire and high-velocity particle impact resistance in a thin, structural form. This innovation offers simultaneous protection against extreme temperature and erosion conditions while maintaining high mechanical strength and manufacturability for large-scale applications.
Description
An advanced polymer composite system designed to protect structural components from severe fire and particle ablation events, such as those occurring during thermal runaway in electric vehicle battery packs.
Unlike
traditional metal shields or ceramic barriers, this material merges structural
integrity, low density, and multifunctional thermal protection within a single
layer. It is suitable for mass-production processes already used in the
automotive and transport industries, enabling an efficient transition from
laboratory prototypes to industrial components.
Advantages
- Dual protection: simultaneously resists flame and high-velocity particle erosion.
- Lightweight and strong: maintains high mechanical performance without metal reinforcement.
- Scalable manufacturing: compatible with standard composite manufacturing processes.
- Improved safety and durability: delays damage progression under extreme thermal events.
- Cost-effective alternative: eliminates the need for multi-layer metal-polymer assemblies currently used in electric vehicle battery enclosures.
