Advanced engineering and materials for superior radome performance
Radomes are produced with cutting-edge processes and high-quality materials to ensure exceptional protection and efficiency. Precise fabrication, rigorous testing, and sustainability are built in.
Production Process Options
Prepreg process: pre-impregnated fibers laid in molds; cured under controlled heat/pressure for uniform compaction and high mechanical properties. Vacuum bagging removes air and improves consolidation; autoclaving completes cure.
Thermoforming: heats plastic sheets (PC, ABS) and shapes by vacuum/pressure—lightweight and cost-effective for medium volumes.
Injection molding (for ABS/PC): high precision and repeatability for complex shapes; draft angles and gate positions optimized for dimensional stability
Precision machining: CNC cutting/shaping for tight tolerances and intricate features; post-machining inspection ensures hole positions and ring interfaces.
Surface treatment: coatings and finishes improve environmental resistance and RF cleanliness (e.g., hydrophobic coatings to reduce water film effects).
Rigorous Testing Technologies
Environmental testing: high/low temperature cycles, humidity exposure, salt spray, UV, and flammability where required.
Mechanical testing: tensile-strength, bending-stiffness, impact energy thresholds, and vibration profiles (sine/random)
Electromagnetic testing: insertion loss, reflection coefficient, transmission efficiency; multi-angle incidence tests for off-axis performance.
Automated test systems: ensure accuracy and repeatability; test scripts log data for traceability.
Environmental Test Matrix (Sample)
- Temperature cycling: −40 °C to +100 °C, 300 cycles, functional checks after demand cycle.
- Humidity: 95% RH @ 40 °C, 240 h, inspect for blistering/delamination.
- Salt spray: per spec duration, check for corrosion/finish degradation.
- UV exposure: accelerated test hours; color/finish stability assessed.
- Flammability: per relevant standard, self-extinguishing behavior documented.
Conclusion
Combining state-of-the-art processes with strict validation yields radomes that are durable, reliable, efficient, and ready for demanding applications.
