Frequently Asked Questions
Product Information
What are Flame Retardant Carbon Fiber Twill Prepreg Sheets from DragonPlate?
DragonPlate's Flame Retardant Carbon Fiber Twill Prepreg Sheets are solid panels made from woven carbon fiber material throughout their thickness, manufactured with flame retardant epoxy resins. These sheets are designed to resist the spread of fire and are suitable for applications in aviation and marine environments. They are easier to machine than uni prepreg sheets and offer better impact resistance and local stress handling. Note: Not all components are guaranteed to pass specific burn tests for every application; customers must verify suitability for their use case.
What sizes and finishes are available for these sheets?
Flame Retardant Carbon Fiber Twill Prepreg Sheets are available in 24" x 24" panels with thicknesses ranging from 0.5" to 1.5". The standard finish is Texture/Texture on both sides. Note: Custom sizes or finishes may require a custom order; contact DragonPlate for details.
What is the difference between 0/90 degree and quasi-isotropic twill prepreg sheets?
0/90 degree sheets have fibers oriented in two directions (0 and 90 degrees), while quasi-isotropic sheets are engineered to approximate uniform properties in all in-plane directions. This affects mechanical performance and may influence suitability for specific applications. Note: Selection should be based on your project's engineering requirements; consult DragonPlate engineering for guidance.
How long does it take for these sheets to ship?
Customers should allow 10-15 days before Flame Retardant Carbon Fiber Twill Prepreg Sheets ship. Note: Lead times may vary based on order volume and customization; contact DragonPlate for current estimates.
Pricing & Plans
What do Flame Retardant Carbon Fiber Twill Prepreg Sheets cost?
Pricing for 24" x 24" sheets varies by thickness and fiber orientation. For example, a 0.5" thick 0/90 degree sheet is $1,905.50, while a 1.5" thick 0/90 degree sheet is $4,590.00. Quasi-isotropic sheets range from $2,268.00 (0.5" thick) to $5,605.00 (1.5" thick). Note: Prices are subject to change and do not include shipping or taxes; check the DragonPlate website for the latest pricing.
Features & Capabilities
What flame retardancy certifications do these sheets have?
The flame retardant carbon fiber veneer used in these sheets is tested and certified to pass the FAR 25.853(a) Appendix F vertical burn specification. However, flame retardancy depends on both the resin system and the geometry, orientation, and integration of the component. DragonPlate cannot guarantee that all structural components will meet or pass specific burn tests for every application. Note: Customers are responsible for verifying compliance with their application's requirements.
How do these sheets perform compared to other carbon fiber sheets?
Flame Retardant Carbon Fiber Twill Prepreg Sheets are generally less stiff than solid uni prepreg sheets but are easier to machine, especially for small parts and detailed contours. They also offer better impact resistance and handle local stresses, such as side and bearing loads, more effectively. Note: For maximum stiffness, consider uni prepreg sheets; for easier machining and impact resistance, twill prepreg sheets are preferable.
Can these sheets be customized for higher flame retardancy?
Yes, many shapes can be manufactured with flame retardant carbon fiber prepreg materials that offer a higher degree of flame retardancy than standard DragonPlate products. These can be made to meet both FAR 25.853 vertical burn testing and smoke and toxicity requirements. Note: Customization may affect lead time and cost; contact DragonPlate engineering for details.
Use Cases & Benefits
What applications are these sheets best suited for?
Flame Retardant Carbon Fiber Twill Prepreg Sheets are ideal for aviation and marine applications where fire resistance is required. Their machinability and impact resistance also make them suitable for detailed parts and components subject to local stresses. Note: For applications requiring guaranteed compliance with specific flame retardancy standards, additional testing or customization may be necessary.
Who should consider using these sheets?
Engineers, designers, and procurement specialists in aerospace, marine, and industrial sectors who require lightweight, fire-resistant, and machinable composite materials should consider these sheets. They are also suitable for applications where impact resistance and local stress handling are important. Note: Not recommended for projects where maximum stiffness is the primary requirement; uni prepreg sheets may be more suitable in those cases.
Technical Requirements & Documentation
Where can I find technical specifications and CAD models for these sheets?
Technical specifications, including weights and performance data, are available on the DragonPlate website at dragonplate.com/dragonplate-weights-specs. Downloadable CAD models can be accessed at dragonplate.com/cad-models. Note: For detailed engineering support, contact DragonPlate directly.
What should I know about verifying flame retardancy for my application?
Flame retardancy is influenced by the resin system, geometry, orientation, and integration of the component into the assembly. While DragonPlate's veneer passes FAR 25.853(a) Appendix F, it is the customer's responsibility to verify that the final component meets the required standards for their application. Note: If additional flame retardancy or certification is required, discuss your needs with DragonPlate engineering before ordering.
Support & Implementation
How can I get engineering support or discuss a custom project?
You can call DragonPlate engineering at 315-252-2559 (Monday–Friday, 8:30am–5:00pm ET) or use the contact form at dragonplate.com/contact-us to discuss your project or request custom solutions. Note: Response times may vary based on inquiry volume.
What is the shipping and return policy for these sheets?
Shipping and return information is available at dragonplate.com/shipping-returns. Note: Custom or made-to-order items may have different return policies; review the terms before purchasing.
Dragonplate solid twill sheets comprise woven material throughout the entire thickness of the panel. These sheets are manufactured using flame retardant epoxy resins that resist the spread of fire, making them ideal for aviation and marine applications. Although not quite as stiff as our solid uni prepreg sheets, these solid twill woven sheets tends to be easier to machine, particularly when cutting small parts, details, and contours.
