NIJ Level III Flexible Conformable Multi-Hit Optimized SiC Composite Ballistic Protection Plate

The High Broad SIC tile employs a fundamentally different approach to ceramic armor. Instead of monolithic tiles, we use precision-formed SiC cylindrical pellets (⌀18mm x 8mm) dispersed in a high-toughness elastomeric matrix. This architecture provides natural crack isolation—damage from one impact does not propagate to adjacent pellets, enabling true multi-hit performance. Compared with Al2O3 pellet systems, our SiC pellets provide 70% higher hardness (2500+ HV vs 1500 HV). Compared with B4C pellet systems, SiC offers virtually equivalent ballistic efficiency at 40-50% lower material cost.

The elastomeric matrix between pellets acts as a crack arrestor. Impact on one pellet causes localized ceramic fracture without crack propagation to neighbors—each pellet functions as an independent protective element.

Unlike rigid tile arrays, the pellet-matrix composite can conform to single-curve and mild double-curve surfaces, making it ideal for contoured vehicle panels and shaped protection components.

SiC pellets (2500+ HV) provide 70% more hardness than Al2O3 pellets (1400-1600 HV), resulting in more effective projectile erosion and fragmentation at the strike face layer.

While B4C pellets offer slightly higher hardness (2800-3200 HV), the cost premium of 2-3x rarely justifies the marginal performance gain. SiC pellets deliver 90% of B4C performance at half the cost.
