Comparative overview
Natural fiber — Flax fiber
Strengths: Renewable, low-density reinforcement with excellent vibration damping, low embodied impact and a distinctive natural surface.
When to use: Select for automotive/interior panels, marine fit-out, sports, furniture and semi-structural parts where sustainability, damping and aesthetics are major drivers.
Key tradeoffs: Moisture sensitivity, batch variability and lower temperature/absolute strength than mineral or carbon fibers; composite end-of-life still depends on the resin.
Qualitative ratings (1–10 scale)
| Relative cost | 3/10 — Low — agricultural feedstock and scalable textile processing keep relative cost low. |
|---|---|
| EM transparency | 9/10 — Excellent — nonconductive, but moisture uptake and natural variability reduce dielectric consistency. |
| Temperature / fire resistance | 2/10 — Low — organic lignocellulosic fiber degrades/ignites at relatively low temperature. |
| Impact / penetration resistance | 5/10 — Moderate — good damping and progressive damage give moderate low-velocity impact tolerance, not ballistic penetration efficiency. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 2/10 — 2/10 | 533.3 kN·m/kg | Family estimate |
| Atmospheric durability | 3/10 — Low — hydrophilic fiber absorbs moisture, swells and can undergo biological/UV degradation; drying, treatments and full matrix encapsulation are essential. |
| Sustainability (CO₂e) | 10/10 — 0.50 kg CO₂e/kg fiber — Very low emissions — data quality: Medium |
