Which is cheaper: dry carbon or wet carbon? | Insights by Supreem Carbon

When considering the procurement of carbon fiber parts, understanding the distinctions between dry and wet carbon fiber is crucial. These differences impact cost, manufacturing processes, performance, and suitability for various applications.

Dry Carbon Fiber

Dry carbon fiber, often referred to as prepreg carbon fiber, involves the use of pre-impregnated carbon fiber sheets that are cured under heat and pressure, typically in an autoclave. This method results in parts with higher fiber volume fractions (55–65%) and lower void content (<1–2%), leading to superior mechanical properties such as increased tensile strength and stiffness. The process is energy-intensive and requires specialized equipment, contributing to higher production costs. Dry carbon fiber is commonly used in applications where performance and durability are paramount, such as in aerospace components, high-performance automotive parts, and critical structural elements.

Wet Carbon Fiber

Wet carbon fiber, or wet layup, involves manually applying resin to dry carbon fiber sheets and curing them, often without the use of an autoclave. This method is less energy-intensive and requires less specialized equipment, resulting in lower production costs. However, it typically yields parts with lower fiber volume fractions (40–52%) and higher void content (2–6%), which can affect mechanical properties. Wet carbon fiber is suitable for applications where cost is a significant consideration, and the performance requirements are less stringent, such as in consumer goods, non-critical automotive parts, and prototyping.

Key Considerations for Procurement

1. Cost Implications: Dry carbon fiber parts are more expensive due to higher material costs and the need for specialized manufacturing processes. Wet carbon fiber parts offer a more cost-effective alternative, suitable for less critical applications.

2. Manufacturing Processes: Dry carbon fiber requires autoclave curing, which is energy-intensive and necessitates precise control over the curing process. Wet carbon fiber allows for more flexibility in manufacturing but may result in parts with less consistent mechanical properties.

3. Performance and Durability: Dry carbon fiber parts generally exhibit superior mechanical properties, making them ideal for high-performance applications. Wet carbon fiber parts may have lower strength and stiffness, which is acceptable for non-critical applications.

4. Applications: Dry carbon fiber is preferred for primary structural components in aerospace and high-performance automotive sectors. Wet carbon fiber is suitable for secondary structures, interior panels, and consumer products where cost considerations are more critical.

Conclusion

Understanding the differences between dry and wet carbon fiber is essential for making informed decisions in the procurement of carbon fiber parts. Assessing the specific requirements of your application, including performance, durability, and budget constraints, will guide you in selecting the appropriate material and manufacturing process.
