Automotive sector is continuously searching for advancements based on productivity & performance. Suppliers as well as manufacturers depend on carbon fiber to decrease weight without compromising strength. But how these advanced materials are made and why should your business consider them?
This blogpost completely explains the manufacturing process and also highlights their importance in automotive development.
What is Carbon Fiber?
Simply put, carbon fiber is a light but strong material that consists of thin fibers made of carbon atoms. Manufacturers cast them into required shapes or weave these fibers into sheets. High‐performance industries such as aerospace, automotive and sports sectors often use carbon fiber.
Properties
Carbon fiber has the following important properties.
- Density: At around 1.6 g/cm³ carbon fiber remains very light.
- Tensile Strength: Carbon fiber provides high tensile strength rated at 500 ksi (kilo pounds per square inch).
- Stiffness: It has a range of 20 to 40 MSI stiffness which makes it best for high‐strength & tough applications.
- Heat Resistance: It withstands temperatures up to 400°F before starting to deteriorate.
Composition
Carbon fiber is composed of three fundamental parts where each of them has a special purpose.
- Carbon Atoms (90%): These atoms give the basic reinforcement which provides the material high strength & hardness.
- Resin (10%): The resin binds the carbon fibers together which increases structural stability and strength under pressure.
- Additives (small amounts): Small amounts of additives maximize certain properties like surface finish & heat resistance.
How Are Carbon Fiber Car Parts Made?
Raw Materials
The production of carbon fiber parts start with polymer precursors such as epoxy resins & polyacrylonitrile PAN. Epoxy resins give durability and strength to the final parts whereas PAN forms the fibers themselves. These raw materials are necessary for manufacturing high‐performance & lightweight carbon fiber parts used in several fields.
Manufacturing Process
The manufacturing process involves multiple steps.
1. Polymer Precursor Treatment
Manufacturers oxidize polymer precursors such as PAN at temperatures up to 300°F. This oxidation strengthens the material.
2. Carbonization
Next, the stabilized precursors are heated in a controlled furnace at a temperature of 2000°F to 3000°F. This step eliminates non‐carbon elements.
3. Fiber Weaving
After that, workers weave carbon fibers into sheets or required patterns. This versatility lets them make personalized shapes for automotive components.
4. Resin Application
At the end a thin resin coating is applied to increase stress resistance and maximize bonding between the fibers.
Lamination
In lamination stage manufacturers precisely place carbon fiber sheets into molds to give them the required shape. They carefully arrange each layer to distribute the load evenly and to increase structural strength. Accurate alignment during layering is necessary to attain the strong & lightweight properties desired in high‐tech automotive manufacturing.
Curing and Finishing
After lamination, the molded carbon fiber parts undergo curing. In this stage, pressure and heat solidify the material which gives maximum mechanical strength. Finally technicians carefully trim and polish the cured parts. This meticulous finishing guarantees a flawless & smooth appearance.
As a result your vehicle obtains high-performance capabilities and refined look that is associated with carbon fiber parts.

Costs of Carbon Fiber Parts
Cost of Carbon Fiber
Carbon fiber is costly; typically in ranges of $10 to $20 per pound. The reason for its high price is the production process which needs complex manufacturing techniques and a lot of energy.
Factors Affecting Cost
A number of important factors influence the final price of carbon fiber. These factors include manufacturing methods, type of fiber as well as adherence to quality standards. In addition, high‐performance or specialized uses－such as luxury sports car parts or aerospace components－usually demand more expensive & complex materials.
Industry Trends
Industries are constantly trying to decrease the costs associated with carbon fiber production. The aim of manufacturers to increase carbon fiber usage is accelerating research into new cost‐effective methods. If successful, these innovations could decrease prices and encourage wider adoption in automotive as well as many other engineering sectors.
Comparison with Other Materials
In terms of weight and strength, carbon fiber outperforms traditional materials like aluminum & steel. Even so, this increased performance comes with a very high price tag. For instance the current price of aluminum is about $2 per pound whereas steel is about $0.25 per pound.
Regardless of high price carbon fiber remains the go‐to choice in fields where durable and lightweight options are more important in contrast to cost savings.
Benefits of Carbon Fiber Parts in Cars
Strength
The high strength of carbon fiber is due to its great tensile strength. It hardly breaks under impact and can withstand very high stress. Conventional materials often fail in such situations but carbon fiber can effectively absorb impacts. Due to this characteristic manufacturers use carbon fiber in car parts to prevent accidents.
Lightweight
Car manufacturers often pick carbon fiber because of its lower weight in contrast to steel. As a matter of fact carbon fiber is five times lighter than steel. By decreasing the weight of a vehicle, carbon fiber parts increase your car’s handling, acceleration as well as performance efficiency. This means your car will have better performance without compromising safety or structural strength.
Eco‐Friendliness
Using carbon fiber parts decreases the weight of your vehicle which directly increases fuel efficiency & indirectly decreases CO2 emissions. Different from metals－whose extraction demands heavy‐duty mining－carbon fiber contributes favorably to sustainability by increasing fuel economy. Moreover carbon fiber gives you a practical way to attain environment‐friendly performance without compromising quality.
Visual Appeal
Carbon fiber parts have a shiny weave pattern that gives a modern look. This unique look is particularly famous in luxury sports cars where it gives them a premium & modern style. In addition to the practical benefits, carbon fiber’s distinct appearance is a symbol of sophistication & automotive innovation.
Challenges and Disadvantages
Cost
The production of carbon fiber involves resource‐intensive & complex processes, which make it very expensive. These high production costs increase the price of vehicles equipped with carbon fiber components. Due to the high costs the use of carbon fiber is mainly limited to exclusive luxury vehicles and not in ordinary everyday vehicles.
Brittleness
Carbon fiber is strong but it lacks flexibility and can break easily. This increases repairs which usually results in higher costs. If you have a car with carbon fiber parts you may face more difficulties in replacement & maintenance because of this brittleness.
Recycling Problems
Although carbon fiber eliminates high fuel consumption & emissions yet recycling the material presents significant challenges.
The thermoset resins used in carbon fiber production make the recycling process challenging which makes it inefficient as well as difficult to reuse the waste parts. As a result several carbon fiber products eventually end up in landfill.
To address the long‐term environmental impacts of carbon fiber, the development of effective recycling methods is necessary.
Susceptibility to Heat
Temperatures above 400°F affect the properties of carbon fiber badly. This is why manufacturers have to use extra heat‐resistant materials to face this limitation. As a buyer this means that you must wisely pick car parts made of carbon fiber.
