Aramid Fiber
Aramid, famously DuPont's Kevlar, is the benchmark fiber in ballistic / protective / reinforcement applications — high strength, very low density (1.44 g/cm³, 1/5 of steel), cut-resistant, self-extinguishing at 400 °C. Para-aramid (Kevlar) for structural reinforcement; meta-aramid (Nomex) for fire-retardant textiles. China's Taihe is already the world's #2 aramid supplier.

Typical applications
Ballistic armor / helmets · Cut-resistant gloves · Optical cable reinforcement · Firefighter suits and fire-retardant materials · Automotive brake pads · Honeycomb cores · Aerospace rigid structure (hybrid laminates with carbon fiber).
High energy absorption (~2× specific energy of carbon) · Cut / puncture resistant · LOI ≥ 28%, self-extinguishing · Lightweight. Downsides: high moisture uptake (interface treatment needed) · Low compressive strength · UV aging · ¥ 100-300 /kg.
