Detailed Description
Aluminum alloy airframes are the default choice for many UAV integrators-until they aren't. Field data from survey VTOL operators shows airframes exceeding 2.8kg suffer 22% shorter mission time and 15% higher motor temperature under continuous load. Worse, coastal deployments expose aluminum to salt spray, accelerating galvanic corrosion at fastener interfaces within 6–8 months.
Our solution: T700 unidirectional prepreg (UD) layup, autoclave cured at 180°C/7bar, resulting in void content ≤1.2% (ASTM D3171). Replacing 6061-T6 aluminum with this carbon plate yields a 45% mass reduction at equivalent flexural stiffness (tested to 850 GPa·mm⁴ section modulus). Surface Ra ≤0.8μm after CNC profiling eliminates delamination risk during routing-critical for thin-wall wing rib sections under ±6g maneuver loads.
Batch-to-batch fiber volume fraction is controlled at 62±2%, fully traceable via production lot records. Each shipment includes material certification and dimensional inspection report. For UAV and light fixed-wing applications requiring legal export compliance, we handle documentation including MSDS and UN transport classification.

Custom FAQ
Q: Can this plate be used for light aircraft wing ribs under EASA CS-23 structural loads?
A: Yes, the T700 UD layup meets CS-23 ultimate load factors when designed per our FEA layup schedule. We provide layup documentation and mechanical test data to support your airworthiness submission.
Q: What CNC tolerances can you hold on 3mm thick plates?
A: Standard ±0.1mm; high-precision option ±0.05mm with anti-delamination tooling paths.
Q: Is legal export clearance supported for carbon fiber plates to EU and North America?
A: Yes. We prepare full export documentation including HS code classification (6815.99), material safety data, and dual-use compliance screening.
