carbon fibre
Carbon fiber is an inorganic high-performance fiber composed of graphite crystallites with a carbon content of >90%, and its core advantages can be summarized as follows:
Core advantages
Ultra-light and high-strength
the density is 1.8g/cm³ (only 1/4 of steel), and the strength can reach 7GPa (10 times that of superalloy steel).
Ultra-high modulus
tensile modulus 200-900GPa (3-10 times that of glass fiber).
Resistant to extreme environments
Temperature resistance > 2000°C in an inert atmosphere, and the coefficient of thermal expansion is almost zero
Functional design
anisotropy control can be achieved through weaving and layup
Graded according to mechanical properties
grade | Tensile Strength (MPa) | Modulus (GPa) | Representative products |
Standard modulus | 3,000-5,000 | 200-250 | T300 (Civilian Mainstream) |
High strength in the medium mold | 5,000-7,000 | 250-300 | T800 (Aerostructure) |
High modulus | 3,500-5,000 | 350-600 | M40J (Satellite Component) |
Ultra-high modulus | 2,000-3,000 | 600-900 | M60J (Precision Instrument) |
Cutting-edge applications
1. Aerospace (35% market share)
Commercial aircraft
50% of the Boeing 787 fuselage is made of carbon fiber (20% weight reduction).
Satellite components
high-modulus carbon fiber/epoxy truss (heat deformation < 0.001%)
Drone
Full carbon fiber fuselage (30% increase in range).
2. New energy and transportation
Wind turbine blades
carbon fiber must be used for the main beam of the blade above 80 meters (fatigue resistance ↑).
Hydrogen energy storage tank
Type IV carbon fiber spiral wound bottle (70MPa pressure resistant).
Supercar body
McLaren P1 monocoque carbon fibre cockpit (40% stiffer).
3. High-end industrial equipment
Semiconductor equipment
Carbon fiber composite wafer handling arm (anti-vibration).
Industrial robots
carbon fiber arm body (speed up and reduce energy consumption at the same time).
4. Medical & Consumer
Prosthetic joints
X-ray permeability + biocompatibility
Bike rack
Tour de France champion
Tennis racket
50% better shock absorption
