Evaluation of the Thermal Diffusivity of Carbon/Phenolic Composites (CPCs) through Oxy-Acetylene Torch (OAT) Test—Part 1: Experimental Characterization and Preliminary Validation

“…From these graphs, it is possible to evidence that in terms of heat capacity above about 800 • C, the value of the C p is considered to possess a gradually increasing, monotonic behavior with no presence of irreversible phenomena [8,9]. For the density of CPCs, it is possible to conclude that above about 800 • C, the value of the ρ of the CPC formulations tend to be considered constant as reported in the literature [60][61][62][63]. In general, in a cubic CPC sample exposed to the torch (Figure 7c), the thermal degradation depends on the depth of the sample we consider with the surface exposed to the harshest conditions (see in-depth temperature profiles in Figure 3 or Figure 4).…”

“…In this figure, we considered an upper temperature limit of 800 • C, i.e., a value in which all the charring processes can be considered completed. [32]; Yellow ▲ from [31]; Red and Blue x from [60]; Red and Blue ▲ from [61]; Red and Blue ⯁ from [62]; Red ⬛ from [63]).…”

“…As a result, assuming our OAT testing conditions, the degradation is highest on the surface of the sample while in the cold part of the test coupon, the material is still virgin (Figure 7c,d) and at room temperature (RT), i.e., the thermo-physical properties are not uniform through the sample. More in detail, if we consider the OAT testing condition [32]; Yellow ▲ from [31]; Red and Blue x from [60]; Red and Blue ▲ from [61]; Red and Blue ◆ from [62]; Red ■ from [63]).…”
