A methodology is proposed for the characterization of fire protection materials with respect to thermal performance models. Typically in these models, materials are characterized by their densities, heat capacities, thermal conductivities, and any enthalpies of reaction or phase changes. For true performance modeling, these thermophysical properties must be determined as a function of temperature for a wide temperature range from room temperature to over 1000 oC. Here, a combined experimental/theoretical/modeling approach is proposed for providing these critical input parameters. Particularly, the relationship between the three-dimensional microstructure of the fire protection materials and their thermal conductivities is highlighted.
