Detailed Description
For structural engineers developing light aircraft frames and UAV primary structures, square tube selection demands verified laminate properties and predictable long-term behavior. Our prepreg square tubes are designed with FEA-driven layup schedules-typically [0°/90°/±45°] quasi-isotropic or customized per your load case. Autoclave cure at 7bar ensures void content ≤1.0% (ASTM D3171), directly correlating to interlaminar shear strength >40MPa.
Fatigue testing per ASTM D3479 shows no strength degradation after 10⁶ tension-tension cycles at R=0.1, 60% UTS. Creep testing at 40% ULT under 1,000hr load hold shows strain growth <0.05%-critical for aircraft structures requiring dimensional stability over years of service.
We supply full mechanical property datasheets including tension, compression, shear, and bearing allowables at room and elevated temperature (+70°C). Batch consistency is enforced via statistical process control on fiber placement angle (±1°), cure temperature profile, and post-cure dimensional verification. Export documentation includes material certification, dual-use screening, and commercial export invoice.
