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 temperature furnaces.
Construction
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.
Dimensional Stability
Solid C/C composite construction will not bow, warp, or crack as a result of thermal shock or cycling.
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.
