Aluminum central frame plates for multi-rotor drones add substantial dead weight, shortening flight duration. Thin aluminum also undergoes permanent bending deformation under landing impact and transmits strong motor vibration to onboard electronics. Our 3K twill hot press carbon fiber plate solves these structural drawbacks via custom prepreg stacking design.
We adopt 3K twill woven carbon prepreg manufactured by hot pressing with precisely controlled heating and pressure curve. The fiber stacking sequence can be customized according to the stress distribution of drone central frame, with void content kept ≤1.0%. Compared to 6061 aluminum plate of equal bending stiffness, our carbon plate reduces weight by 55%. It maintains stable dimension under continuous cyclic vibration and resists permanent deformation after repeated landings. CNC operations including grooving, drilling and contour cutting can be processed directly without obvious interlayer delamination.
This panel is widely used for multi-rotor drone central frame, motor mount base and battery support plate. It keeps stable mechanical performance within -35℃~115℃, retaining over 92% strength after 500h damp heat aging test.

FAQ
Q1: Can we adjust fiber layup to suppress frame vibration?
A1: Yes, our engineers tune 0°/90°/±45° fiber stacking based on FEA analysis to reduce vibration transmission.
Q2: Does CNC grooving cause delamination?
A2: Strict hot press curing ensures strong interlayer bonding, greatly lowering delamination risk during CNC processing.
