CARBON-CARBON COMPOSITE MATERIALS WITH 3D REINFORCEMENT FUNCTIONAL PROPERTIES DEPENDENCES RESEARCH

Abstract

The article presents the researchresults on the empirical dependencies ofa carbon-carbon composite material (CCCM) with orthogonal reinforcement (3D) characteristics (specific electrical resistance, thermal conductivity coefficient, dynamic elastic modulus, coefficient of thermal linear expansion, density). The definition of these characteristics was made in accordance with the regulatory documents (GOST and ASTM). Based on the tests and calculations results, a number of formulas were obtained that describe the empirical relationships between the characteristics of the material. According to these formulas it is possible to calculate the value of the sought-for material characteristic from known values of one or several characteristics through the calculated constant for a given relationship. It should be noted that the formulas and graphical dependencies given in the article are valid only for this particular material.
