BZNCarbon’s 3D carbon-carbon composite (C/C) materials are advanced carbon fiber-reinforced carbon structures built to meet the needs of industries where strength, heat resistance, and longevity are essential. Unlike 2D composites that rely solely on fibers in two planar directions, 3D C/C composites incorporate reinforcement in all three axes (X, Y, Z), enabling them to withstand complex thermal and mechanical stresses.

Available in standard and custom geometries—including disks, plates, and blocks—our 3D C/C composites can also be tailored using various weave architectures such as XYZ woven, axial-radial-hoop (also known as hoop 3D), or as per your proprietary design.

BZNCarbon is one of the few producers capable of achieving a minimum bulk density of 1.90 g/cm³, thanks to specialized HIP equipment, significantly enhancing the strength-to-weight performance.

What Is 3D Carbon-Carbon Composite?

3D C/C composite is a high-strength, high-temperature resistant material composed of carbon fibers embedded in a carbon matrix. The fiber orientation covers all three spatial axes, delivering isotropic mechanical reinforcement and increasing fracture toughness, dimensional stability, and thermal fatigue resistance.

This structural configuration allows for longer service life, improved heat distribution, and better resistance to internal cracking under thermal cycling or impact loads—particularly in aerospace braking systems and industrial high-heat environments.
