Product Description
This dual-ceramic composite strike face represents a breakthrough in armor material engineering. By combining pressureless sintered SiC as the front strike layer with B4C R400 as the rear defeat layer, we achieve NIJ Level IV protection with an optimal balance of cost, weight, and multi-hit performance that neither material could deliver alone.
- SiC Strike Layer: The front 8mm pressureless sintered SiC layer provides superior multi-hit toughness and fracture resistance. SiC's higher fracture toughness (3.5-4.0 MPa*m1/2) absorbs initial projectile impact energy and blunts the penetrator tip through controlled micro-fracture
- B4C R400 Defeat Layer: The rear 7mm B4C R400 layer capitalizes on extreme hardness (3000+ HV) to defeat the already-blunted penetrator, with ultra-low density minimizing overall plate weight
- Synergistic Interface: The polyurethane interlayer between SiC and B4C acts as an acoustic impedance mismatch, reflecting shock waves and further dissipating impact energy
- Cost Optimization: Using SiC for 55% of the ceramic volume reduces material cost by 30% versus an all-B4C plate while maintaining Level IV performance
| Impact Phase | Layer | Mechanism |
|---|---|---|
| Phase 1: Dwell | SiC Strike Layer | Ceramic dwell erodes projectile tip; high toughness prevents radial cracking |
| Phase 2: Penetration | B4C R400 Defeat Layer | Extreme hardness shatters blunted core; low density arrests residual penetration |
| Phase 3: Arrest | Composite Backing | UHMWPE or aramid backing catches ceramic fragments; BFS minimized |
Supplied as a bonded ceramic composite sub-assembly, ready for integration with UHMWPE or aramid backing by armor plate manufacturers. Available in SAPI, ESAPI, and Swimmer cut geometries. Both SiC and B4C layers are produced via our cost-efficient pressureless sintering process, ensuring supply chain scalability.
OEM Partnership: We welcome collaboration with body armor manufacturers for custom hybrid plate configurations. Joint development programs available for specialized threat requirements including VPAM, GOST, and bespoke security specifications.
