Composite pressure vessel is a pressure vessel whose structure is made of composite material. It is designed to withstand internal pressure using graphite and aramid, or glass fiber in a polymeric matrix.
Composite Rigid Board is produced by laminating multiple layers of rigidized graphite felt between 0.025″ thick sheets of carbon composite. The graphite foil may be bonded to one or both faces. It 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.It provides a robust barrier, which protects the insulating core from damage by dropped parts.
