• Autoclave cured
• Quasi isotropic layup with 0°, 90°, and ±45° orientations
• Local reinforcement at bead seat and high-load zones
• Toughened epoxy resin system with a high glass transition temperature (Tg 230–260°C)
• Designed using Finite Element Analysis (FEA)
• Validated for radial, cornering, and torsional loads
• Low deflection under hard braking and lateral G-forces
• Strong resistance to impact and bead-seat deformation

Fastening

• Grade-10.9 hardware 
• Preload torque calculated to maintain joint integrity without crushing the carbon flange
• Sealing O-ring bead between faces to prevent moisture intrusion into laminate edge
• Torque Spec: 140ft/lb

The inner barrel is coated with a ceramic thermal barrier coating (TBC) designed to withstand extreme brake heat.
