Measured Data
Specific Heat
Experiments for specific heat [J/(kg K)], or heat capacity, were conducted using a heat flow meter on unconditioned and dried samples at 10 °C, 20 °C, 30 °C and 40 °C.
Unconditioned
| Temperature (C) | Specific Heat Mean (J/kg-K) | Standard Deviation (J/kg-K) |
|---|---|---|
| 10.0 | 1379.0 | 8.0 |
| 20.0 | 1403.0 | 6.0 |
| 30.0 | 1439.0 | 1.0 |
| 40.0 | 1459.0 | 7.0 |
Thermal Conductivity
Experiments for thermal conductivity [k] were conducted using a heat flow meter on unconditioned samples at 15 °C and 45 °C.
Unconditioned
| Temperature (C) | Conductivity Mean (W/m-K) | Standard Deviation (W/m-K) |
|---|---|---|
| 15.0 | 0.133 | 0.004 |
| 45.0 | 0.144 | 0.003 |
Mass Loss Rate (MLR)
Mass loss rate [kg/s] was measured in cone calorimeter experiments at three heat fluxes: 25 kW/m2, 50 kW/m2, and 75 kW/m2.
This material warps and intumesces after ignition. An edge frame and wire grid were used to limit this behavior, yet the sample still expanded vertically through the wire grid, in some cases by more than 2 cm. One additional replicate was conducted per heat flux level without the wire grid to acquire more accurate time to ignition data (HF25_R2, HF50_R4, HF75_R4). Another test was conducted at 25 kW/m2 without either the edge frame or wire grid (HF25_R1) to observe the material burning behavior without intervention.
