Comparative overview
High-performance mineral fiber — Engineered mineral fiber
Strengths: Inorganic, non-conductive reinforcement positioned between glass and carbon for stiffness, damage tolerance and temperature resistance.
When to use: Select for aeronautic, marine, mobility and safety structures needing dielectric behavior and better performance than ordinary glass at lower cost than premium carbon.
Key tradeoffs: Smaller supply base and qualification history; product-specific mineral chemistry and long-term durability require verification.
Qualitative ratings (1–10 scale)
| Relative cost | 6/10 — Moderate–high — engineered mineral chemistry and small production scale place it above common glass/basalt. |
|---|---|
| EM transparency | 8/10 — Very good — nonconductive mineral fiber with useful dielectric behavior. |
| Temperature / fire resistance | 9/10 — Excellent — very high melting/softening temperatures and strong fire resistance. |
| Impact / penetration resistance | 5/10 — Moderate — moderate toughness; public low/high-velocity penetration data are limited. Stored TDS elongation: 2.1%. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 2/10 — 2/10 | 688.5 kN·m/kg | Product TDS |
| Atmospheric durability | 8/10 — Very good — engineered mineral fiber is largely insensitive to UV; moisture durability depends on exact mineral chemistry, sizing and interface. |
| Sustainability (CO₂e) | 8/10 — 2.20 kg CO₂e/kg fiber — Low emissions — data quality: Low |
