Certified UL94 V-0 Fire Safety for Regulated Applications
Standard epoxy carbon fiber sheets burn readily when exposed to open flame. To eliminate this fire hazard, we engineer our flame retardant carbon fiber sheets with an advanced, halogen-free fire-inhibiting epoxy resin system that meets the strict UL94 V-0 standard. Specifically, upon direct flame contact, the composite material forms an intumescent char barrier that cuts off oxygen supply. Consequently, it self-extinguishes within 10 seconds with zero flaming drips. Furthermore, for eVTOL aircraft, commercial UAVs, and battery enclosures, this design provides critical passive fire containment without sacrificing lightweight structural integrity.
High Specific Strength with Minimal Weight Penalty
Traditional fireproof materials like heavy steel or aluminum sheeting add substantial deadweight to critical structures. In contrast, our fire-retardant composite plates utilize 100% continuous Toray carbon fiber reinforcement. Specifically, our chemical formulation adds less than 2% to overall material density while retaining over 95% of standard carbon fiber tensile and flexural modulus. Therefore, aerospace and automotive engineers maximize payload capacity and battery efficiency while satisfying demanding international safety mandates.
Thermal Stability and Low Smoke Toxicity
In enclosed environments such as passenger aircraft cabins, rail cars, and electronics enclosures, toxic smoke inhalation poses an immediate threat during accidents. For this reason, our halogen-free chemical formulation significantly suppresses optical smoke density and toxic gas emissions during thermal runaway events. Moreover, with a continuous operating threshold between 130°C and 150°C (and high-Tg options reaching 200°C), our composite plates preserve precise dimensional stability under severe environmental heat.

Production Process
We manufacture our flame retardant carbon fiber sheets using high-pressure hydraulic hot-press molding. Specifically, this controlled process ensures maximum fiber consolidation, maintains void content under 1%, and delivers a precise resin-to-fiber ratio. Here is our step-by-step manufacturing workflow:
- FR Prepreg Selection & Cutting — We select aerospace-grade Toray carbon fiber fabrics pre-impregnated with modified UL94 V-0 epoxy resin and cut them using automated CNC knife cutters.
- Engineered Ply Layup — Our technicians stack prepreg layers in cleanroom conditions following custom ply schedules (0°/90° or quasi-isotropic [0°/±45°/90°]) to prevent post-cure warp.
- High-Pressure Hot Press Molding — We apply uniform thermal ramp-up and multi-ton hydraulic pressure to eliminate internal micro-voids and complete resin crosslinking.
- Demolding & Surface Treatment — We run a controlled cooling cycle before precision demolding, yielding a pinhole-free matte or glossy surface finish.
- Multi-Axis CNC Machining — Our workshop executes custom machining according to CAD drawings (.DXF/.STEP), including pocketing, beveling, countersunk screw holes, and threading.
- Flame & Mechanical Testing — Our lab conducts batch vertical burn verification (UL94 V-0 compliance), measures Tg values, and runs inter-laminar shear strength tests.
- Final Quality Inspection — We perform 100% dimensional caliper verification, thickness tolerance inspection, surface gloss audits, and protective film packaging.
