Composite Rigid Board Insulation
Developed to provide all the advantages of conventional graphite rigid board
insulation, but able to withstand the added demands of modern high
Composite Rigid Board (CRB) is produced by laminating multiple
layers of rigidized graphite felt between 0.025" thick
sheets of Carbon/Carbon Composite (C/C). Optionally, graphite
foil may be bonded to one or both faces.
Sizes: Boards are manufactured to
customer specified sizes, eliminating the need for most joints.
Panels are available in sizes up to 90" long x 55" wide
x 8" thick.
||Erosion Resistance: C/C composite exterior
provides a robust barrier; protecting the insulating core from
damage by dropped parts, melt splatter, or high velocity particle
abrasion. Fabricating hot zone panels as single monolithic sheets
eliminate most joints; a significant source of particle generation.
|| Machinability: CRB is readily machinable
with conventional methods such as cutting, drilling, sawing,
and milling. Panels may be supplied with pre-machined shiplap
joints to facilitate rapid furnace rebuilds.
||Dimensional Stability: Solid C/C composite
construction will not bow, warp, or crack as a result of thermal
shock or cycling.
