What are the main advantages of PTFE glass fiber cloth in the aerospace field?

PTFE (polytetrafluoroethylene) glass fiber cloth is a high-performance composite material that combines the excellent chemical properties of PTFE and the high strength characteristics of glass fiber. In the aerospace field, it has the following main advantages:

Teflon PTFE Coated Fiberglass Fabric

Excellent high temperature resistance
Spacecraft will face extreme high temperature environments when flying at high speed or returning to the atmosphere. PTFE glass fiber cloth can work stably for a long time at temperatures as high as 200-260℃, and some modified materials can even withstand higher temperatures, effectively protecting the internal structure of the spacecraft from high temperature damage.

Excellent chemical stability
There are many chemical substances in the aerospace environment, such as fuels, oxidants, etc. PTFE glass fiber cloth has extremely strong chemical inertness, hardly reacts with any chemical substances, can resist erosion by corrosive media, and extend the service life of the material.

Low friction coefficient and self-lubrication
PTFE itself has an extremely low friction coefficient (about 0.05-0.1). The use of PTFE glass fiber cloth in aerospace mechanical components can reduce friction and wear between components, reduce energy consumption, improve mechanical efficiency, and reduce maintenance costs.

Good electrical insulation performance
Aerospace equipment contains a large number of electronic components and circuit systems, which require reliable insulation materials. PTFE glass fiber cloth has excellent electrical insulation, can maintain stable electrical performance under high voltage and high frequency conditions, prevent arcing and short circuits, and ensure the safe operation of aerospace equipment.

Lightweight and high-strength characteristics
The combination of the high strength of glass fiber and the lightweight characteristics of PTFE allows PTFE glass fiber cloth to maintain high strength while not increasing the weight burden of the spacecraft. This is crucial for the weight reduction design of aerospace vehicles and helps to improve payload and flight performance.

Weather resistance and anti-aging performance
Spacecraft are exposed to harsh environments such as ultraviolet rays and high-energy particle radiation in space or the atmosphere for a long time. PTFE glass fiber cloth has good weather resistance and anti-aging properties, can resist the influence of these environmental factors, and maintain the stability of material properties.

Processability and formability
PTFE glass fiber cloth can be processed into different shapes and structures through a variety of processes, such as films, fabrics, coatings, etc., which can meet the customization needs of complex components in the aerospace field and are widely used in thermal insulation layers, sealing materials, cable insulation layers and other parts.
