Impact of carbon fiber on electrical and thermal properties of fluoranhydrite based composites

The object of research is the impact of carbon fiber on the electrical and thermophysical properties of a mineral matrix, as well as the possibility of the modifier being used as a micro-heating element. Method. Conventional test methods, combined with modern research methods, including differential thermal calorimetry, were used to study the development of mechanical, electrical, and thermophysical characteristics, as well as physicochemical properties of fluoranhydrite-based material. Results. The suggested approach to reduce the specific resistivity has proven to be effective. Mixes with low specific resistivity can be used to produce composites based on fluoranhydrite and carbon fiber. The analysis of thermophysical properties of large-size items based on the developed composition proved the possibility of using the items in resistive heating systems.
