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.

Features:

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.

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.

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