With the development of high-performance fields such as aerospace, new energy vehicles, and sports equipment, the demand for carbon fiber materials is growing. Carbon fiber, as a lightweight and high-strength material, has excellent mechanical properties. In the carbon fiber family, "high modulus carbon fiber" and "high strength carbon fiber" are often used as core materials for different applications. This article will systematically compare these two types of carbon fiber materials from the aspects of performance parameters, application scenarios, cost and selection recommendations, to help purchasers, engineers and technical R&D personnel to make scientific selections.
If you need to purchase or wholesale high modulus carbon fiber or high strength carbon fiber, you can contact Revolve CF carbon fiber material supplier, email: HarveyXu@revolve-cf.com, official website address: https://www.revolve-cf.com
High Strength Carbon Fiber: The main feature is high tensile strength, usually above 4,000 MPa;
High Modulus Carbon Fiber: The main feature is high tensile modulus, usually above 400 GPa.
High strength carbon fiber focuses on tensile fracture resistance, while high modulus carbon fiber focuses on rigidity and deformation control ability.
| Performance index | High-strength carbon fiber | High modulus carbon fiber |
| Tensile strength (MPa) | 4000~7000 | 2500~3500 |
| Tensile modulus (GPa) | 230~300 | 400~800 |
| Elongation at break (%) | 1.5~2.5 | 0.3~1.0 |
| Density (g/cm³) | 1.75~1.80 | 1.78~1.82 |
| Thermal conductivity | Medium | Low |
| Cost | Medium | High |
Aerospace structural parts (such as helicopter blades, wing beams)
Automotive parts (such as anti-collision beams, door frames)
Sports equipment (such as high-end tennis rackets, bicycle frames)
Features: Strong ability to withstand impact loads, suitable for structural parts with high strength requirements
Satellite truss structure
High-precision robotic arm
Optical platform and radar support
Precision measuring instrument frame
Features: small strain, high stability, suitable for high-end equipment with extremely high rigidity and thermal stability requirements.
High modulus carbon fiber precursor is more difficult to prepare and has a more stringent firing process, so the price is usually 1.5~2 times that of high-strength carbon fiber.
The above is a reference price. For actual purchases, please contact Revolve CF carbon fiber material supplier for quotation.
High-strength carbon fiber:
Easy to weave and laminate;
Compatible with a variety of resin systems;
Good impact toughness and fatigue resistance.
High modulus carbon fiber:
Difficult to weave, and laminated products are more brittle;
Susceptible to microcracks, stress dispersion needs to be strengthened in the design;
Usually used for non-load impact parts or controlled environments.
If you are more concerned about the strength and impact toughness of the structural parts, it is recommended to choose high-strength carbon fiber;
If you are concerned about dimensional stability, rigidity and lightweight limits, it is recommended to use high modulus carbon fiber;
For scenarios that require both rigidity and strength, medium-high modulus strength balanced carbon fiber can be selected.

In the process of selecting carbon fiber materials, weighing strength and rigidity, performance and cost is a realistic problem that every engineering designer must face. Only by properly matching material properties with application requirements can performance and return on investment be maximized.
