Flame Retardant Carbon Fiber I-Beams

Combining the classic structural member with modern carbon fiber composites, DragonPlate flame retardant carbon fiber I-beams are an excellent light-weight solution for solving structural problems. They are manufactured using a flame retardant epoxy resin, making them ideal for aviation and marine applications. These reinforcement carbon fiber I-beams are extremely strong in bending and shear loading. The combination of uni-directional and 0°/90° plain weave on the top and bottom flanges give the I-beam its high bending strength. Utilizing a ±45° orientation in the webbing allows the carbon fiber I-beam to have exceptional shear strength, as well as properly transmitting loads between the top and bottom flanges. These properties cannot be obtained as efficiently with pultruded I-beams, as all of the fibers run along the length of the I-beam. DragonPlate’s I-beam construction allows for an extremely thin, lightweight I-beam to obtain the same effect as a thicker, heavier pultruded I-beam. Carbon fiber I-beams can offer similar properties in bending and shear as sandwich panels with the same thickness, but without the added weight from unnecessary core material. With a textured finish on the top and bottom, our carbon fiber I-beams are perfect for bonding to thin panels to create an extremely stiff and strong structure.

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.
