..., or 500 ksi) and stiffness (132 GPa, or 19 × 10 6 psi) were possible. Aramid fiber is unusual in that it is technically a thermoplastic polymer (like nylon), but rather than melting when heated, it decomposes before reaching its projected melting temperature. With polymerization, it forms rigid...
