Markforged Onyx FR-A 800cc filament

Fire-Resistant Strong Filament Onyx FR-A Markforged

Fire-Resistant Strong Filament Onyx FR-A Markforged is an innovative material for 3D printing. It's designed for manufacturing components that combine fire resistance and high strength. Onyx FR-A is nylon reinforced with chopped carbon fiber. It's optimally suited for applications in industries such as aerospace, transportation, and automotive.

Key Features and Benefits of Markforged Onyx FR-A

Onyx FR-A material possesses a number of key features that ensure its demand in areas with high reliability requirements:

Fire Resistance: at a thickness of 3 mm or more, the material is self-extinguishing and complies with the V-0 standard. This parameter is confirmed by a UL Blue Card certificate.

High Mechanical Strength: Onyx FR-A can be reinforced with continuous carbon fibers. When using Carbon Fiber FR-A as a reinforcing material, parts made from Onyx FR-A achieve strength comparable to 6061-T6 aluminum.

Full Traceability: the material provides transparency and control over batch origin.

Compliance with Strict Standards: the material is certified for most parts printed in accordance with the requirements of standard 14 CFR 25.853.

Wide Compatibility: the filament is suitable for all Markforged X-series industrial 3D printers, including models X7, X5, and X3.

Technical Specifications of Onyx FR-A

The material has the following parameters, which make it a reliable choice for complex projects:

• Tensile Strength: 40 MPa (5.8 ksi) according to ASTM D638.
• Tensile Modulus: 3 GPa (440 ksi) according to ASTM D638.
• Flexural Strength: 71 MPa (10.3 ksi) according to ASTM D790.
• Flexural Modulus: 3.6 GPa (520 ksi) according to ASTM D790.
• Heat Deflection Temperature: 145 °C (293 °F) according to ASTM D648 B.
• Density: 1.2 g/cm³.

It should be noted that strength characteristics depend on the print direction. Maximum strength is achieved when the print vector coincides with the direction of applied load.

Compliance with FST Standards (Fire Resistance, Smoke, Toxicity)

Onyx FR-A filament has been successfully tested for compliance with FAR 25.853 Appendix F, Part (a)(1)(i) and (ii) at a thickness of 2 mm. The material also meets smoke emission requirements (FAR 25.853 Appendix F, Part V, at a thickness of 3.7 mm) and combustion toxicity requirements (BSS 7239 Flaming at a thickness of 2 mm).

Reinforcement Capabilities and Compatibility

The material is compatible with various continuous fibers such as Carbon Fiber FR-A, Carbon Fiber, HSHT Fiberglass, Kevlar, and Fiberglass. This allows for the creation of components with improved mechanical properties. It's worth noting that Carbon Fiber FR-A is used exclusively with Onyx FR-A.
