Carbon Nanotube Toughened Boron Carbide |
NanoLab was awarded a Phase II SBIR contract by US Army to develop a high toughness boron carbide composite containing carbon nanotubes. NanoLab developed hot pressing and pressureless sintering protocols for this B4C-CNT composite and can now manufacture various shapes using our 50 Ton hot press. For mechanical properties of this composite, see below. Please contact us directly for ballistic properties and armor applications of this material.
We routinely produce following products:
Tiles: 4" x 4", larger on request
Disks: 3" diameter, larger on request
Spheres: Up to 7 mm in diameter
Shapes: Square pyramids, other shapes on request. |
