Composite Sandwich Board Insulation
Composite Sandwich Board (CSB) has been engineered to provide maximum longevity for CVD and sintering furnaces. Alternating layers of graphite foil and semi-rigidized felt are sandwiched between sheets of Carbon/Carbon composite. Much like Composite Sandwich Pack, this construction provides an effective barrier to process gas infiltration and convection.
Construction
CSB is produced by laminating multiple layers of semi-rigidized felt and graphite foil 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.
Innovative Construction
Multiple graphite foil layers slow the infiltration of process gasses that can densify felt, degrading its insulating properties.
Erosion Resistance
C/C exterior provides a robust barrier; protecting the insulating core from damage by dropped parts, melt splatter, or high velocity particle abrasion.
Dimensional Stability
Solid C/C composite construction will not bow, warp, or crack as a result of thermal shock or cycling.
Machinability
Composite Sandwich Board (CSB) is readily machinable using conventional methods such as cutting, drilling, sawing, and milling.
