High-Strength 3K Carbon Fiber Woven Fabric: A Lightweight Revolution for Marine, Aerospace, and Automotive Applications
Product Overview
High-Strength 3K Carbon Fiber Woven Fabric is crafted from small-tow carbon fibers composed of 3,000 filaments, woven through precision processes to form a highly dense structure—combining exceptional strength with lightweight properties. With a density of only 1.79g/cm³ (about 1/5 that of steel), it boasts a tensile strength of up to 4120MPa and a tensile modulus of 234GPa, far exceeding traditional metal materials. Impregnated and cured with Lloyd’s-certified epoxy resin, this material forms a high-hardness, corrosion-resistant composite, ideal for demanding applications in marine, aerospace, and automotive industries.
Core Advantages
-
Extreme Lightweight & High Strength
- This material is between 30% and 50% lighter than aluminum alloy but offers a strength that’s 35 times greater than steel. It greatly cuts down on structural weight while boosting load-bearing capacity. For example, marine applications can achieve 30%-50% hull weight reduction, boosting fuel efficiency by 15%-20%.
- In aerospace, rocket engine casings using 3K carbon fiber reduce weight by 40%, with tensile strength reaching 2630MPa—far surpassing high-strength steel (1705MPa).
-
Superior Corrosion Resistance & Stability
- Resistant to acids, alkalis, and salt spray, maintaining performance stability even in harsh environments (e.g., high-humidity, high-salt marine conditions).
- Withstands temperatures up to 300°C, and its low thermal expansion coefficient ensures dimensional stability under extreme temperatures—ideal for high-heat scenarios like aerospace engine compartments and automotive exhaust systems.
-
Precision Craftsmanship & Flexible Processability
- The fine weave of 3K small-tow carbon fibers enables molding into complex structures via processes like compression molding, injection molding, and Vacuum-Assisted Resin Transfer Molding (VARTM)—suitable for marine deflectors, aircraft wing skins, and automotive lightweight components.
- Xiaomi SU7 Ultra uses a 3-layer 3K carbon fiber front hood (1.73㎡), achieving a balance of lightweight and high strength through prepreg technology, contributing to its Nürburgring track performance breakthrough.
