In terms of lightweight armor materials systems, boron carbide (B,C) was selected as the ceramic material. B,C is a very lightweight (density 2.52 gdcm'), very hard (hardness 35 GPa) ceramic [ 11, and these properties make it the best ceramic choice for lightweight body armor. Aluminum has been chosen as the metal material for infiltration3M Advanced Materials Division 3M 10B Enriched Boron plates and cylinders are possible. We have extensive experience pressing boron carbide, boron nitride, silicon carbide, titanium and zirconium diborides, aluminum nitride and several customer proprietary materials.

5 Lightweight Protective Materials Ceramics, Polymers

Amorphization has limited the effectiveness of boron carbide to high-velocity threats. Modification of the crystal structure via the ternary alloying chemistry of boron carbide may inhibit amorphization. This would provide an armor material that is 25 percent less dense than SiC and 40 percent less dense than Al 2 O 3. Findings. Finding 5-1a.AC-130H Gunship Armor Upgrade Project (Technical ReportThe advantage of B4C/A1 over monolithic ceramic armor is its higher toughness. The ballistic efficiency of B4C materials, relative to hot-pressed boron carbide, was found to be directly related to the initial boron carbide content, the B-C-A1 phases formed in situ, and their continuity.Alumina Plate Silicon Carbide Plate tradekoreatradeKorea is a online B2B trade website offers you matching services to connect buyers and suppliers.
