What is delaminated carbon fiber and how does it affect part performance? | Insights by Supreem Carbon

1. What is delaminated carbon fiber?

Delamination refers to the separation of layers within a composite material, such as carbon fiber-reinforced polymers (CFRPs). In CFRPs, delamination occurs when the bond between layers fails, leading to a loss of structural integrity. This can result from manufacturing defects, mechanical stress, or environmental factors.

2. How does delamination affect part performance?

Delamination compromises the mechanical properties of carbon fiber parts, particularly their compressive strength. Studies have shown that specimens with embedded delamination exhibit a significant decrease in compressive strength compared to intact specimens. For instance, specimens with surface delamination experienced a reduction of approximately 30.86 MPa in compressive strength.

3. What are the common causes of delamination in carbon fiber composites?

Delamination can result from several factors, including:

• Manufacturing Defects: Improper resin infusion, contamination, insufficient pressure during curing, and inadequate curing processes can lead to weak interlayer bonds.

• Mechanical Stress: Excessive impact, vibration, or fatigue during usage can cause layers to separate over time. ((https://www.supreemcarbon.com/article/analysis-of-delamination-problems-in-carbon-fiber-products-and-how-to-avoid-it.html?utm_source=openai))
• Environmental Factors: Prolonged exposure to moisture and thermal cycling can weaken the bond between layers. ((https://www.supreemcarbon.com/article/analysis-of-delamination-problems-in-carbon-fiber-products-and-how-to-avoid-it.html?utm_source=openai))

4. How can delamination be prevented in carbon fiber products?

Preventive measures include:

• Optimized Manufacturing Processes: Ensuring thorough surface preparation, uniform resin application, proper pressure during curing, and controlled curing conditions.

• Material Selection: Choosing high-quality, compatible resins and fibers, and using pre-preg materials for consistent bonding. ((https://www.supreemcarbon.com/article/analysis-of-delamination-problems-in-carbon-fiber-products-and-how-to-avoid-it.html?utm_source=openai))
• Design Optimization: Avoiding sharp corners and abrupt transitions, and strategically orienting fibers to handle anticipated loads. ((https://www.supreemcarbon.com/article/analysis-of-delamination-problems-in-carbon-fiber-products-and-how-to-avoid-it.html?utm_source=openai))
• Post-Manufacturing Quality Control: Implementing non-destructive testing methods like ultrasonic testing, X-ray, or thermography to detect voids or weak spots.

5. What are the disadvantages of carbon fiber in automotive applications?

While carbon fiber offers high strength-to-weight ratios, it also presents challenges such as high material and production costs, complex and expensive repairs, intricate manufacturing processes, unique crash performance characteristics, and growing environmental concerns.

6. How does porosity affect carbon fiber composites?

Porosity, the presence of small voids within the composite, can weaken the material, decrease its stiffness, and increase the risk of delamination. High levels of porosity are detrimental to the structural integrity of carbon fiber components.

7. What are the common mistakes when ordering custom carbon parts?

Common mistakes include overlooking surface finish and clearcoat requirements, underestimating lead times and tooling costs, selecting suppliers without verifying capabilities, poor technical communication, and neglecting testing, validation, and certifications. Avoiding these mistakes ensures better quality and performance of the final product. ((https://www.supreemcarbon.com/common-mistakes-ordering-custom-carbon-parts.html?utm_source=openai))

8. How does delamination affect the residual compressive capacity of carbon fiber laminates?

Delamination significantly reduces the residual compressive capacity of carbon fiber laminates. The extent of reduction depends on the type and location of the delamination. For example, specimens with surface delamination experienced a decrease of approximately 30.86 MPa in compressive strength.
