Is carbon fiber stronger than steel but more brittle? | Insights by Supreem Carbon

1. Is Carbon Fiber Stronger Than Steel?

Yes, carbon fiber exhibits a higher specific strength than steel. Specific strength, or strength-to-weight ratio, is a material's tensile strength divided by its density. For instance, carbon fiber (AS4) has a tensile strength of 4,300 MPa and a density of 1.75 g/cm³, resulting in a specific strength of approximately 2,457 kN·m/kg. In contrast, low carbon steel (AISI 1010) has a tensile strength of 365 MPa and a density of 7.87 g/cm³, yielding a specific strength of about 46.4 kN·m/kg. This indicates that carbon fiber is significantly stronger per unit weight than steel.

2. Is Carbon Fiber More Brittle Than Steel?

Carbon fiber composites are generally more brittle than steel. While they possess high tensile strength, they lack the ductility of steel, making them more susceptible to sudden failure under certain conditions. This brittleness is a critical consideration in applications where impact resistance is essential.

3. What Are the Advantages of Using Carbon Fiber Parts?

Carbon fiber parts offer several advantages, including:

• High Strength-to-Weight Ratio: Provides strength without adding significant weight, enhancing performance and fuel efficiency in automotive and aerospace applications.
• Corrosion Resistance: Unlike metals, carbon fiber does not corrode, leading to longer service life and reduced maintenance costs.
• Design Flexibility: Can be molded into complex shapes, allowing for innovative designs and integration into various structures.

4. What Are the Challenges in Procuring Carbon Fiber Parts?

Procurement challenges include:

• Cost: Carbon fiber parts are typically more expensive than their steel counterparts, which can impact budget considerations.
• Manufacturing Complexity: Requires specialized processes and equipment, potentially leading to longer lead times and higher production costs.
• Quality Control: Ensuring consistent quality and performance across all parts is crucial, necessitating rigorous testing and quality assurance measures.
