Thermal Conductivity and Heat Capacity of Ablative Thermal Protective Carbon Fiber

The results of a study of the thermophysical properties of ablative heat-shielding carbon fiber with a matrix based on phenol-formaldehyde resin randomly reinforced with short carbon fibers obtained from carbon fabric based on viscose of the “Ural” type are presented. These studies were carried out using differential scanning calorimetry, thermogravimetry, and the laser flash method. To describe the obtained data, a model is proposed that allows one to estimate the thermal conductivity of the manufactured carbon fiber.
