2.5D Carbon-Carbon Composite Materials

Discover BZNCarbon’s 2.5D carbon-carbon composite—designed for extreme temperature environments. Ideal for aircraft brakes and structural components with high strength, thermal stability, and wear resistance.

BZNCarbon offers precision-engineered 2.5D carbon-carbon composite materials manufactured through multi-directional carbon fiber reinforcement and high-temperature processing. Compared to standard 2D composites, the 2.5D structure includes interlaminar fiber reinforcement, delivering enhanced durability in dynamic and high-friction environments.

This material is ideal for aerospace-grade components, particularly aircraft brake discs, where high mechanical strength, low weight, and thermal stability are essential. Each product is processed at temperatures exceeding 2000°C and tested to ensure reliable performance under demanding conditions.

What Is 2.5D C/C Composite?

2.5D carbon-carbon composites are an evolution of 2D structures, built from stacked carbon fiber fabric layers with added reinforcement in the through-thickness (Z) direction. This limited Z-direction reinforcement provides improved shear strength without significantly increasing weight or cost, making 2.5D composites a strategic choice for friction materials and thermal shielding in aerospace, defense, and industrial sectors.

Additional Information

Depending on the application, this material is also referred to as:
CFC, Carbon Composite, C/C, Carbon Fiber Composite, Carbon Reinforced Carbon, Carbon-Carbon

While all these names point to the same base technology, the 2.5D architecture offers a balance between cost efficiency and mechanical reinforcement, making it a preferred option in applications where 3D composites may be too heavy or expensive.
