Quartz Honeycomb is a low density low loss honeycomb core material specially designed for the use in spacecraft Synthetic Aperture Radar (SAR), Optical Sensor Systems, Radomes, low dielectric related applications and other structures which must be positioned with accuracy and stability in order to properly perform their intended purpose. Quartz Honeycomb core is durable and easy to work with. We’ve had success in slicing the honeycomb core to 0.050±0.002″ thickness.
The dielectric constant and the loss tangent factor of Quartz are the most distinguished amongst all mineral fibers. Properties of UQF-105-1/4-3.0 honeycomb core test at average frequencies of 9.5 GHz:
The Quartz Honeycomb core has a unique feature of low Coefficient of Thermal Expansion (CTE). Below are comparisons of CTE in the thickness direction of various honeycomb cores.
Ultracor Inc. manufactures a honeycomb core structure out of Astroquartz® fibers and space qualified Cyanate Ester resin (UQF-105-1/4-3.0). Mechanical properties are found in the table below.
Ultracor can make Quartz honeycomb in other configurations per our customer’s requirements.
ULTRACOR® PRODUCT DESIGNATIONS
Ultracor® products are designated by use of a series of letters and numbers, as follows:
UQF-105-1/4-3.0, in which:
“U” represents Ultracor® HONEYCOMB
“QF” indicates that the material used is Quartz Fiber
“105” determines the product code number under which the details of construction are documented.
“1/4” indicates a 1/4” cell size.
“3.0” indicates a nominal density in pounds per cubic foot. (lbs/ft³)
