HONEYCOMB RADAR ABSORBER
C-RAM HC is a series of radar absorbing products made from Nomex/phenolic or glass/phenolic honeycomb with a proprietary lossy coating. Typically, Nomex/phenolic is used in most applications. The hexagonal open cell structure provides a high strength-to-weight ratio, making C-RAM HC an ideal material for aircraft parts, such as fairings, covers, and leading edges, which must combine strength, light weight, and low radar cross section. Honeycomb is also ideal for cavity backed spiral antenna applications. The open cells permit forced air cooling, allowing high-power applications. On special order skins can be provided on the core, typically glass, Kevlar, or AstroQuartz skins can be provided. Custom composite shapes are also available per customer drawings.
C-RAM HCGR X/Y:
Gradient loaded flat sheets with reflectivity as follows, where X = thickness and Y=reflectivity.
0.500" -15 dB minimum 10GHz to 18 GHz
0.750" -15 dB minimum 8 GHz to 18 GHz
1.000" -15 dB minimum 6 GHz to 18 GHz
C-RAM HCGI X/Y:
Gradient loaded flat sheets with insertion loss tuned to customer requirements, where X = thickness in inches and Y = insertion loss in dB/inch. Maximum insertion loss is 20 dB/inch.
C-RAM HCUI X/Y:
Uniformly loaded flat sheets with insertion loss tuned to customer requirements, where X = thickness and Y = insertion loss in dB/inch. Maximum insertion loss is 30 dB/inch.
