The application of ETFE membrane material welding in the aerospace field

ETFE Film Material, with its lightweight properties (density: 1.7 g/cm³) and extreme environmental resistance, has emerged as an ideal material for aerospace applications:

Aircraft & Spacecraft

Applications:

• Thermal barrier welding for cabin interiors (e.g., window sunshades in passenger aircraft)
• Liner welding for fuel tanks (requires aviation fuel corrosion resistance)
• Protective film welding for satellite solar panels (requires radiation resistance)

Key Requirements:

• Welds must pass helium leak detection (leakage rate ≤1×10⁻⁹ Pa·m³/s)
• Magnetic interference-free welding process (to avoid disrupting navigation systems)
• Compliance with military standards

Recommended Equipment:
Puxiong High-Temperature Welding Machine (with electromagnetic shielding).

High-Altitude Research Balloons

Case Studies:

• NASA Super Pressure Balloons
• China’s "Jimu-1" Aerostat

Key Requirements:

• Ultra-thin film welding (0.05–0.2 mm) for weight reduction
• Welds to withstand temperature cycles (-80°C to +60°C)
• Dynamic tensile resistance during ascent (e.g., 10g acceleration overloads)

Recommended Equipment:
High-Frequency Induction Welding Machines with micron-level precision control.

Note: Critical welding parameters must align with material thickness gradients and structural load distribution patterns.
