Product type
Carbon fiber prepreg is a composite material consisting of carbon fibers pre-impregnated with a resin system. This combination allows for enhanced strength-to-weight ratios, making it a popular choice in various high-performance applications. The prepreg is typically cured under heat and pressure to form a solid structure, resulting in a lightweight yet extremely strong final product.
| Fiber type | High modulus or standard modulus carbon fibers |
| Resin system | Epoxy, phenolic, or polyester |
| Thickness | 0.1 mm to 5 mm |
| Width | Up to 1.5 meters |
| Cure temperature | Typically between 120°C and 180°C |
| Storage conditions | Refrigerated at -18°C or lower |
When selecting carbon fiber prepreg, consider the type of carbon fiber and resin system that best suits your application requirements. Specify the thickness and width needed for your project, as well as the desired cure temperature. Additionally, inquire about storage conditions to ensure material integrity. Certifications and tolerances may also be relevant depending on industry standards.
