Polyimide pre-oxidized silk blended composite fabric

Thermal Stability, Flame Retardancy, and High-Temperature Resistance: Polyimide fibers have a long-term temperature resistance of up to 260℃ and a momentary temperature resistance exceeding 300℃; pre-oxidized fibers have a temperature resistance ≥400℃. After the two are combined, the base fabric maintains structural stability in high-temperature environments, with a strength retention rate >90% (300℃). Inherent Flame Retardancy: Polyimide has a limiting oxygen index (LOI) as high as 44, and pre-oxidized fibers have an LOI >45. After blending, the base fabric is self-extinguishing and drip-free, only carbonizing during combustion with extremely low smoke density, meeting the high safety requirements of aviation, fire protection, and other applications. Excellent Mechanical Properties, High Strength, and Wear Resistance: Polyimide fibers have a tensile strength of 4.0 GPa and a modulus of 160 GPa; pre-oxidized fibers have a high modulus and creep resistance. After compounding, the base fabric's tear resistance and puncture resistance are significantly improved, suitable for high-wear scenarios. Flexible and Lightweight: Density 1.41 g/cm³, it can be cut and sewn into complex shapes, reducing weight by more than 30% compared to metal, suitable for lightweight design in aerospace. Chemical and Environmental Stability, Corrosion Resistance: Stable against weak acids, weak bases, organic solvents, and oils, suitable for corrosive environments such as garbage incineration and chemical filtration. Anti-UV Aging: Composite coatings (such as nano-titanium oxide) can absorb ultraviolet rays, extending the outdoor service life. Functional Design, Surface Modification: Plasma treatment can impart hydrophilicity (contact angle reduced from 121.5° to 68.5°) or antibacterial properties (E. coli inhibition rate >64%). Electromagnetic Shielding: Combined with metallized coatings (such as aluminum foil), an electromagnetic wave shielding rate >95% can be achieved.

Thermal Stability and Flame Retardancy

High-Temperature Resistance Polyimide fiber has long-term temperature resistance up to 260℃ and instantaneous temperature resistance exceeding 300℃; pre-oxidized fiber has temperature resistance ≥400℃. After the two are combined, the base fabric can maintain structural stability in high-temperature environments, with a strength retention rate >90% (300℃).

Inherently Flame Retardant Polyimide has a limiting oxygen index (LOI) as high as 44, and pre-oxidized fiber LOI >45. After blending, the base fabric is self-extinguishing and drip-free after removing the flame, only carbonizing during combustion with extremely low smoke density, meeting the high safety requirements of aviation, fire protection, etc.
