Detailed Description
7075-T6 aluminum UAV arms permanently bend at >5J ground impact, shifting thrust vector 2–4° and forcing PID re-tuning that drains battery ~18% per flight. Salt spray at arm-hub joints accelerates crevice corrosion.
Feature: T700 UD ±10° off arm axis, autoclave cured, 4.0m CNC router profile cut.
Advantage: σt ≥2100MPa, density 1.52g/cm³, ILSS >38MPa at climb-cut edges, void ≤1.2%.
Benefit: 44% lighter than 7075-T6 → lowers moment of inertia, faster attitude recovery; elastic recovery below yield-arm returns true after sub-ULT impact; no corrosion; flatness ±0.05mm/300mm for motor-mount faces.
Cold-chain tracked from -18°C prepreg storage to finished part. Batch FVF 62±2%. Export compliant.

FAQ
Q: Pre-drilled M3/M4 motor holes?
A: Yes, CMM verified ±0.03mm position tol.
Q: Vibration damping vs Al?
A: Damping ratio 2–3× Al → attenuates 80–120Hz motor harmonics reaching FC.
Q: Elastic recovery threshold?
A: Returns to <0.05mm offset if impact <85% ULT. Beyond that inspect for delamination.
Q: MOQ prototype?
A: 5 pcs std size; custom profile 10 pcs.
Q: Export docs?
A: HS 6815.99, MSDS, CO, batch cert, dual-use screening.
