2.The tensile modulus of aramid fiber is 3 times that of steel wire, 2 times that of glass fiber and 10 times that of high-strength nylon industrial wire.
3.The continuous use temperature range of aramid fiber is extremely wide, which can use for a long time from -196℃ to +330℃. Shrinkage rate can be zero under the condition of 150 ℃, and can melt with high temperature of over 560 ℃.
4.Mechanical properties: strength: 3.6 GPa, elongation modulus: 131 GPa, breaking elongation: 2.8 %.
5.Thermal performance: the long-term use of temperature: 380 ℃, the axial thermal expansion coefficient: - 2 x 10 ^ (6)/K, thermal conductivity: 0.048 W (m, K).
