Frequently Asked Questions
Product Information: Flame Retardant Carbon Fiber Hat Stiffeners
What are DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners?
DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners are structural components designed to increase panel stiffness and structural performance, especially when used with flame retardant carbon fiber sheets. They are manufactured using a flame retardant epoxy resin and feature a combination of plain weave carbon fiber in both 0°/90° and ±45° orientations, with unidirectional carbon fiber added to the cap for enhanced stiffness and strength along the length. The design results in a high stiffness-to-weight ratio and greater torsional rigidity when bonded compared to an I-beam. Note: Flame retardancy depends on both the resin system and the geometry, orientation, and integration of the component; customers must verify compliance for their specific application.
What sizes and finishes are available for Flame Retardant Carbon Fiber Hat Stiffeners?
Two standard sizes are available: 1" x 1" x 48" (SKU: FDPHS*FR-1x1x48) and 1.5" x 2" x 48" (SKU: FDPHS*FR-1.5x2x48), both with a textured finish on the outside and flange surfaces to optimize bonding. Custom thicknesses, leg lengths, and finished lengths are available upon request. Note: Custom orders may require additional lead time; contact DragonPlate for details.
What is the price of DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners?
The 1" x 1" x 48" hat stiffener is priced at $300.44, and the 1.5" x 2" x 48" version is priced at $334.94. For large quantity orders or custom sizes, contact DragonPlate for a quote and manufacturing lead times. Note: Prices are subject to change and do not include shipping or taxes.
What is the typical lead time for shipping Flame Retardant Carbon Fiber Hat Stiffeners?

Features & Capabilities
What makes DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners suitable for aviation and marine applications?
These hat stiffeners are manufactured using a flame retardant epoxy resin system and are designed to provide high stiffness-to-weight ratios, making them ideal for applications where weight, strength, and flame resistance are critical. The unidirectional carbon fiber in the cap enhances longitudinal stiffness, and the textured finish improves bonding. Note: Customers must verify that the product meets the specific flame retardancy and regulatory requirements for their application.
Do DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners meet FAR 25.853(a) Appendix F vertical burn specifications?
The flame retardant carbon fiber veneer used in these products is tested and certified to pass FAR 25.853(a) Appendix F vertical burn specification. However, flame retardancy of the final structural component depends on the resin system, geometry, orientation, and integration into the assembly. DragonPlate cannot guarantee that a standard component will meet specific burn testing for every application; customers are responsible for verifying compliance. For higher flame retardancy, components can be manufactured with flame retardant carbon fiber prepreg materials to meet both FAR 25.853 vertical burn and smoke/toxicity requirements. Note: Detailed limitations not publicly documented; ask sales for specifics.
Can DragonPlate manufacture custom flame retardant carbon fiber hat stiffeners?
Yes, DragonPlate offers custom fabrication for flame retardant carbon fiber hat stiffeners, including custom thicknesses, leg lengths, and finished lengths. Many shapes can also be made with flame retardant carbon fiber prepreg materials for higher flame retardancy. Contact DragonPlate engineering to discuss your specific requirements. Note: Custom orders may require additional lead time and minimum order quantities.
Compliance & Certifications
What quality and compliance certifications does DragonPlate hold?
DragonPlate products are manufactured under ISO 9001:2015 quality standards at their facility in Elbridge, New York. For security and compliance, DragonPlate has completed a CMMC Level 1 Self-Assessment (submitted to SPRS) and a NIST SP 800-171 Self-Assessment to meet DFARS 252.204-7012 requirements. The company is actively advancing its cybersecurity program to meet CMMC Level 2 requirements. Note: For further details, contact service@dragonplate.com or call 315-252-2559.
Are DragonPlate flame retardant carbon fiber products biocompatible or radiolucent?
DragonPlate offers biocompatible and radiolucent materials tailored to meet stringent regulatory requirements, particularly for medical and defense industries. For flame retardant products, customers should confirm specific biocompatibility or radiolucency needs with DragonPlate engineering. Note: Not all flame retardant products are biocompatible or radiolucent by default; verification is required for each application.

Use Cases & Limitations
What are typical use cases for DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners?
These hat stiffeners are commonly used to increase panel stiffness and structural performance in aviation, marine, and other applications requiring flame resistance and lightweight strength. They can be easily incorporated into existing designs and are suitable for projects where high stiffness-to-weight ratio and torsional rigidity are needed. Note: Suitability for specific regulatory or performance requirements must be verified by the customer.
What limitations should I be aware of when using DragonPlate Flame Retardant Carbon Fiber Hat Stiffeners?
Flame retardancy is dependent on the resin system, geometry, orientation, and integration of the component into the assembly. DragonPlate cannot guarantee that a standard component will meet specific burn testing for every application. Customers are responsible for verifying that the product meets all regulatory and performance requirements for their use case. For applications requiring higher flame retardancy, custom fabrication with prepreg materials is available. Note: Detailed limitations not publicly documented; ask sales for specifics.
Do you have a design that needs increased panel stiffness? Are you looking to increase the structural performance of our flame retardant carbon fiber sheets? Solve your problems with DragonPlate's flame retardant carbon fiber hat stiffeners. They can easily be incorporated into existing designs to increase the structural performance by adding stiffness.
Our carbon fiber hat stiffeners are comprised of plain weave carbon fiber in both 0°/90° and ±45° orientations, with 0° uni-directional carbon fiber to add stiffness and strength along the length of the hat stiffener. They are manufactured using a flame retardant epoxy resin, making them ideal for aviation and marine applications. To optimize the design, we have added the unidirectional only to the cap of the hat stiffener. This fiber placement lets us create a stronger and stiffer hat stiffener while minimizing hat stiffener weight. This design creates a high stiffness to weight ratio, and also creates a beam that is more torsionally rigid when bonded than an i-beam. The carbon fiber hat stiffener has a textured finish on the outside and on the flange surfaces to create an ideal bonding surface.
Dragonplate flame retardant structural carbon fiber materials are manufactured with the same flame retardant epoxy resin system used to create our flame retardant carbon fiber veneers. The carbon fiber veneer is tested and certified to pass the FAR 25.853(a) Appendix F vertical burn specification. Since flame retardancy is dependent upon both the resin system, as well as the geometry, orientation, and integration of the components into the overall assembly, we cannot guarantee any particular standard flame retardant structural component will meet and pass the specific burn testing necessary for your application. It is the responsibility of the customer to verify that these carbon fiber materials will meet the requirements for any specific application. If additional flame retardancy is required, many shapes can also be made with flame retardant carbon fiber prepreg materials, which have a higher degree of flame retardancy than our standard Dragonplate flame retardant products, and can be manufactured to meet both FAR 25.853 vertical burn testing, as well as smoke and toxicity requirements. Call us any time to discuss your project with engineering.
