FAQ
Q1: Why choose triangular over circular cross-section?
A1: Triangular design provides:
• Mechanical superiority: 40% higher bending stiffness and 25% better torsion resistance vs round tubes at equal weight;
• Connection ease: Flat surfaces enable stronger adhesive bonding/mechanical fastening;
• Space efficiency: Allows dense honeycomb-like packing for structural optimization;
• Aerodynamics: Reduces vortex shedding in airflow (critical for drone arms).
Q2: How to connect carbon fiber tubes with metal parts?
A2: Three proven solutions:
Adhesive bonding: Epoxy structural adhesive (30MPa+ shear strength) with sandblasted surfaces;
Hybrid joining: Adhesive + titanium fasteners (insulating washers prevent galvanic corrosion);
Embedded inserts: Pre-molded metal sockets (for mass production) with >50kN pull-out strength.
Q3: Performance under extreme temperatures?
A3: Depends on resin matrix:
• Standard epoxy: -50℃~120℃ (80% strength retention at peak temperature);
• High-temp resin: -196℃~180℃ (suitable for cryogenic to engine bay environments);
• Unique trait: Below -30℃, thermal conductivity drops to 0.5W/m·K (superior anti-thermal bridging vs metals).
Q4: Maintenance guidelines?
A4: Key practices:
Cleaning: pH-neutral detergents only (acetone damages resin);
Inspection: Tap-test every 6 months (hollow sound indicates delamination);
UV protection: Required for outdoor applications;
Repair: Damage <5mm repairable with carbon patches + vacuum infusion.
Q5: How to verify product quality?
A5: Three essential tests:
Ultrasonic C-scan: Checks internal porosity (aerospace grade requires <1%);
3-point bending test: Verifies <5% deviation from theoretical flexural strength;
Accelerated aging: 2000hrs salt spray + 3000 thermal cycles.
