Thermal Conductivity of FyreRoc Systems

摘要

FyreRoc Material Systems are used in many applications utilizing the material's high temperature properties. In most of these applications metal and/or a high temperature insulation is being displaced by the FyreRoc system for a variety of reasons ranging from weight to thermal behavior. The insulating properties of FyreRoc and the capability of building insulating constructions is one of the important characteristics allowing FyreRoc to compete against the presently available high temperature systems. To demonstrate the advantage of the FyreRoc's as an insulation system, requires being able to measure the thermal conductivity at elevated temperatures for various laminates and sandwich constructions. These thermal conductivity values for FyreRoc systems will then allow for the engineering of the cold side temperatures and thus optimization of thickness and weight for applications such as bulkheads, engine compartments and firewalls. This paper will report thermal conductivity data on the various constructions and laminates along with retention of strength for these systems after high temperature exposures. Discussion of these results and how they compare with present systems will also be included.
