Top Four Applications of Biaxial Carbon Fiber Fabric in Composites
— The Symphonic Strength of 0° & 90° Fibers
Biaxial carbon fiber fabric (0°/90° weave) combines high strength, high modulus, and bidirectional isotropy, making it the “universal skeleton” for lightweight composites. The following four scenarios have seen large‑scale industrial adoption and can be directly replicated in your next project.
1. Drone Wings: One Fabric Bearing All Lift
- Specification: 3K biaxial prepreg, 200 g/m², layup [0/90]₄, total thickness 1.0 mm
- Advantage: Equal strength in both directions; replaces aluminum spars to reduce weight by 45 % and increase torsional stiffness by 70 %
- Production: Vacuum‑bag cure at 120 °C, cycle time 45 min per panel
2. Automotive Chassis Reinforcement Plates: Turning “Steel” into “Fabric”
- Specification: T700 biaxial carbon fiber fabric + epoxy RTM, areal weight 300 g/m²
- Result: Reduces vehicle longitudinal beam mass by 2.8 kg per car, increases lateral stiffness by 30 %, and improves NVH attenuation by 3 dB
3. Solid Rocket Motor Casings: Specific Strength Equals Range
- Specification: High‑strength, intermediate‑modulus biaxial fabric (IM7 grade), resin content 32 %
- Outcome: Casing mass ↓ 35 %, range ↑ 15 %, validated on PAC‑3 and M51 missile systems
4. Building & Bridge Reinforcement: Transforming Concrete into “Steel”
- Specification: Biaxial 600 g/m² wet‑lay fabric + epoxy impregnation, field‑applied wet
- Data: Triples flexural capacity of beam soffits, installation completes in 1 day, extends service life by 30 years
One‑Sentence Summary
Biaxial carbon fiber fabric uses two perpendicular fiber orientations to fully engage both 0° and 90° loading; whether flying in the sky, driving on the road, or spanning a bridge, it is the most cost‑effective “all‑purpose rebar.”
