1. Ultimate Specific Strength: Every Gram Counts
T300 3K unidirectional sheets deliver a tested tensile strength of 3 530 MPa at just 1.55 g/cm³, giving a specific strength 6× that of 7075‑T6 aluminum alloy.
Drone Wing Skins: A mere 0.8 mm thickness supports a 5 kg payload—cutting weight by 42 %.
Robot Joint Housings: For the same stiffness, wall thickness can be reduced by 33 %, dropping motor inertia by 18 %.
2. Directional High Stiffness: Fiber Orientation = Stiffness Orientation
3K Carbon Fiber Sheets can be laid in 0°/±45°/90° orientations to match load paths exactly.
Automotive Chassis Reinforcements: A hybrid 0° + ±45° layup boosts torsional stiffness by 2.8×, reducing body roll by 1.2°.
Optical Mounting Platforms: High‑modulus M40J 3K sheets in 0° principal orientation keep micro‑stage drift under 1 µm.
3. Ultra‑Thin Formability: Even 0.2 mm Can Be 3D Shaped
With single‑ply thickness as low as 0.10 mm, 3K carbon fiber sheets accommodate autoclave, vacuum bag, and compression molding—enabling complex contours, edges, and honeycomb sandwich structures in one shot.
Consumer Laptop Lid Panels: 0.6 mm 3K twill weave sheet bonded to a 0.2 mm magnesium alloy backplate—total lid thickness under 14 mm.
Foldable Drone Rotor Arms: 0.5 mm sheets molded with a 90° bend radius of 3 mm without delamination.
4. EMI & Weather Resistance: Structural Parts That “Pass Waves and Hide”
A dual‑layer design—outer 3K twill weave plus inner UD high‑modulus—provides both electromagnetic transparency and load bearing.
5G Base Station Radomes: Dielectric constant εᵣ ≈ 3.8, loss tangent tan δ ≈ 0.003, signal loss < 0.2 dB.
Marine Drones: Fluorocarbon surface coating over 3K sheet survives 1 000 h salt‑spray with zero corrosion or blistering.
5. Rapid Production & Controlled Cost: From Prototype to Volume in 7 Days
Roll widths of 1 270 mm with laser slitting tolerance ±0.2 mm enable:
Small Batches: Laser cutting + vacuum bagging, 3‑day lead time.
Large Batches: 1 × 4 compression mold, 2‑min cycle, cost approaching stamped aluminum.
One‑Sentence Summary
3K Carbon Fiber Sheets trade every gram of weight for tons of performance—offering higher strength, higher stiffness, lower weight, plus ultra‑thin formability, EMI compatibility, and lightning‑fast volume production.
