Carbon fiber is one of the most widely used composite materials in various industries, such as aerospace, automotive, sports, and art. It has many advantages over other composite materials, such as fiberglass and Kevlar, but also some drawbacks. Here is a brief comparison of carbon fiber with other composite materials:
- Carbon fiber has the highest strength-to-weight ratio among the common composite materials. It can support more load with less mass than fiberglass or Kevlar. This makes it ideal for applications where weight reduction is important, such as airplanes, cars, bikes, etc.
- Carbon fiber is also very stiff and rigid, meaning it can resist deformation under stress. It has a higher modulus of elasticity than fiberglass or Kevlar, meaning it can withstand more force before bending or breaking. This makes it suitable for applications where high performance and precision are required, such as rockets, satellites, robots, etc.
- Carbon fiber is resistant to heat, corrosion, and wear, meaning it can endure harsh environments and conditions. It has a higher thermal conductivity than fiberglass or Kevlar, meaning it can dissipate heat more efficiently. It also has a lower coefficient of thermal expansion than fiberglass or Kevlar, meaning it can maintain its shape and size better when exposed to temperature changes. This makes it useful for applications where stability and durability are needed, such as wind turbines, bridges, buildings, etc.
- However, carbon fiber is not without its challenges. It is more expensive and difficult to produce than fiberglass or Kevlar, requiring specialized equipment and skills. It also has lower fracture toughness and fatigue resistance than fiberglass or Kevlar, meaning it can break more easily under sudden or repeated stress. This makes it vulnerable to impact damage and cracks, which can compromise its strength and performance.
- Carbon fiber is also more difficult to design and fabricate than fiberglass or Kevlar, requiring complex methods and techniques. It is not isotropic like metals, meaning it does not have the same properties in every direction. It depends on the orientation and arrangement of the carbon fibers within the polymer matrix. This presents opportunities for customization and optimization, but also challenges for analysis and simulation.
- Carbon fiber is a composite material that has many advantages over other composite materials in terms of strength-to-weight ratio, stiffness, rigidity, thermal conductivity, and dimensional stability. However, it also has some drawbacks in terms of cost, complexity, fracture toughness, fatigue resistance, and impact damage. Therefore, the choice of the best composite material for a given project depends on the design objectives, budget constraints, environmental factors, safety requirements, etc.
Strength Test Shows How Carbon Fiber Compares To Steel, Other Metals
One of the most common questions people have about carbon fiber is how strong it is compared to steel and other metals. To answer this question, we can look at a YouTube video that shows how different materials react to a hydraulic press. The video features carbon fiber, PVC, acrylic, aluminum, titanium, and steel plates that are subjected to increasing pressure until they break or deform.
The video demonstrates the strength and weakness of each material in a simple and visual way. It also provides some numerical data on the force applied and the thickness of each plate. Here is a summary of the results:
Material | Thickness (mm) | Force (kN) | Result |
---|---|---|---|
PVC | 10 | 5 | Breaks |
Acrylic | 10 | 10 | Breaks |
Carbon Fiber | 10 | 15 | Breaks |
Aluminum | 10 | 20 | Deforms |
Titanium | 10 | 25 | Deforms |
Steel | 10 | 30 | Deforms |
The results show that carbon fiber is stronger than PVC and acrylic, but weaker than aluminum and titanium. Steel is the strongest material, but also the heaviest. Carbon fiber is five times lighter than steel, but also five times weaker.
However, these results do not tell the whole story. There are many factors that affect the strength of a material, such as:
- The type and quality of the material
- The shape and size of the material
- The direction and distribution of the force
- The temperature and humidity of the environment
- The presence of defects or damage in the material
Therefore, to compare the strength of carbon fiber and steel more accurately, we need to use more specific and standardized measurements, such as:
- Tensile strength: The maximum force a material can withstand before breaking when stretched
- Compressive strength: The maximum force a material can withstand before breaking when squeezed
- Shear strength: The maximum force a material can withstand before breaking when cut or twisted
- Bending strength: The maximum force a material can withstand before breaking when bent
- Impact strength: The maximum force a material can withstand before breaking when hit by an object
These measurements are usually expressed in units of megapascals (MPa) or gigapascals (GPa), which are equivalent to newtons per square meter (N/m2). Here is a table that compares the average values of these measurements for carbon fiber and steel:
Measurement | Carbon Fiber (GPa) | Steel (GPa) |
---|---|---|
Tensile strength | 3.5 | 0.4 |
Compressive strength | 1.5 | 0.4 |
Shear strength | 0.1 | 0.3 |
Bending strength | 0.8 | 0.2 |
Impact strength | 0.02 | 0.15 |
The table shows that carbon fiber has higher tensile, compressive, and bending strength than steel, meaning it can support more load per unit of area when stretched, squeezed, or bent. However, carbon fiber has lower shear and impact strength than steel, meaning it can support less load per unit of area when cut, twisted, or hit.
These values also depend on the type and quality of carbon fiber and steel used, as well as the fabrication methods and design possibilities. For example, carbon fiber can be made with different types of fibers, such as PAN (polyacrylonitrile), pitch (coal tar), or rayon (cellulose). It can also be made with different types of resins, such as epoxy, polyester, or vinyl ester. These variations affect the properties and performance of carbon fiber.
Similarly, steel can be made with different types of alloys, such as carbon steel, stainless steel, or alloy steel. It can also be made with different types of treatments, such as annealing, quenching, or tempering. These variations affect the properties and performance of steel.
In conclusion, carbon fiber and steel have different strengths and weaknesses depending on the type of test, material, and application. Carbon fiber is stronger than steel per unit of weight, but weaker than steel per unit of volume. Carbon fiber is ideal for situations where weight reduction is important, such as aerospace and automotive industries. Steel is better for situations where high strength and durability are required, such as skyscrapers and bridges.

Carbon Fiber: A Composite Building Material Stronger Than Steel
Carbon fiber is not only a strong and light material, but also a composite material. This means that it is made of two or more different materials that are combined to create a new material with enhanced properties. In the case of carbon fiber, the two main components are carbon filaments and polymer resin.
Carbon filaments are thin strands of carbon atoms that are bonded together in a regular pattern. They are usually derived from organic materials, such as polyacrylonitrile (PAN), pitch (coal tar), or rayon (cellulose). These materials are heated and stretched to form long and thin fibers that have high tensile strength and stiffness.
Polymer resin is a liquid or solid substance that can harden and bind the carbon filaments together. It can be either thermoset or thermoplastic, depending on whether it can be melted and reshaped or not. Thermoset resins, such as epoxy, polyester, or vinyl ester, are more common for carbon fiber because they have higher strength and durability.
The process of making carbon fiber involves several steps, such as:
- Spinning: The raw material is spun into fine threads that are wound onto spools
- Stabilizing: The threads are heated and oxidized to prevent them from burning
- Carbonizing: The threads are heated to very high temperatures to remove non-carbon elements and form carbon filaments
- Surface treatment: The filaments are treated with chemicals or plasma to improve their bonding with the resin
- Sizing: The filaments are coated with a protective layer to prevent damage and improve handling
- Winding: The filaments are wound onto bobbins or spools for storage or transportation
The resulting carbon filaments can be used in various ways to create different forms of carbon fiber, such as:
- Woven fabric: The filaments are woven into a cloth-like material that can be cut and draped over a mold
- Unidirectional tape: The filaments are aligned in one direction and bonded with resin to form a flat and stiff material that can be stacked and laminated
- Continuous fiber: The filaments are fed directly into a mold or die where they are impregnated with resin and cured to form a solid shape
- Chopped fiber: The filaments are chopped into short pieces and mixed with resin to form a paste or slurry that can be molded or sprayed
The fabrication methods and design possibilities of carbon fiber are endless. It can be twisted, woven, molded, or 3D printed into various shapes and forms. It can also be combined with other materials to create hybrid composites, such as:
- Carbon fiber reinforced polymer (CFRP): A composite of carbon fiber and polymer resin that has high strength-to-weight ratio and stiffness-to-weight ratio
- Carbon fiber reinforced metal (CFRM): A composite of carbon fiber and metal that has high thermal conductivity and electrical conductivity
- Carbon fiber reinforced ceramic (CFRC): A composite of carbon fiber and ceramic that has high heat resistance and abrasion resistance
Carbon fiber is used in many applications where strength, lightness, flexibility, and durability are required, such as:
- Aerospace: Carbon fiber is used for aircraft wings, fuselages, propellers, rockets, satellites, etc.
- Automotive: Carbon fiber is used for car bodies, chassis, bumpers, spoilers, etc.
- Sports: Carbon fiber is used for bikes, skis, golf clubs, tennis rackets, etc.
