How does manufacturing differ for dry carbon vs wet carbon? | Insights by Supreem Carbon

In the realm of carbon fiber parts manufacturing, understanding the differences between dry and wet carbon processes is crucial for making informed procurement decisions. These methods significantly influence the quality, performance, and cost of the final product.

Dry Carbon Fiber Manufacturing

Dry carbon fiber manufacturing involves the use of pre-impregnated carbon fiber sheets, known as prepregs, which are pre-impregnated with resin. This process offers several advantages:

• Enhanced Quality Control: Prepregs provide consistent resin content and fiber alignment, resulting in parts with superior mechanical properties.

• Reduced Labor Intensity: The automated nature of prepreg lay-up reduces manual labor and the potential for human error.

• Superior Surface Finish: The controlled resin application leads to smoother surfaces, reducing the need for extensive post-processing.

However, this method also presents challenges:

• Storage and Handling Requirements: Prepregs require refrigerated storage to maintain resin stability, which can increase operational costs.

• Limited Shelf Life: The resin in prepregs has a finite shelf life, necessitating careful inventory management.

• Higher Material Costs: The advanced technology and materials involved contribute to higher costs compared to wet lay-up methods.

Wet Carbon Fiber Manufacturing

Wet carbon fiber manufacturing, or hand lay-up, involves manually applying resin to dry carbon fiber sheets. This traditional method offers:

• Flexibility: Suitable for low-volume and custom parts, allowing for design modifications without significant cost increases.

• Lower Initial Investment: The equipment and setup costs are generally lower, making it accessible for small-scale operations.

However, it also has drawbacks:

• Inconsistent Quality: Manual application can lead to variations in resin distribution and fiber alignment, affecting part strength and durability.

• Labor-Intensive Process: The reliance on manual labor increases the potential for human error and can lead to higher labor costs.

• Surface Imperfections: Achieving a smooth surface finish may require additional post-processing steps.

Key Considerations for Procurement

When sourcing carbon fiber parts, consider the following:

• Quality Assurance: Ensure suppliers implement rigorous quality control measures, including material testing and inspection protocols.

• Supplier Certifications: Look for certifications such as ISO 9001, indicating adherence to quality management standards.

• Customization Capabilities: Assess the supplier's ability to meet specific design requirements and provide customization options.

• Lead Times and Minimum Order Quantities (MOQs): Discuss production timelines and order sizes to align with project needs.

• Cost Implications: Evaluate the cost-effectiveness of the manufacturing method in relation to the desired part performance and quality.
