Theoretical Description of Electrophysical Properties of Syntactic Carbon Foams

Abstract:

Syntactic carbon foams represent a new class of advanced composite materials with the ordered structure. They have unique heat transfer, stress-strain, electophysical and other performance properties. Syntactic foams feature a regular structure based on a ratio of solid and gaseous volumes. The paper specifies the area of application for syntactic carbon foams in the various manufacturing sectors. Another promising area for application of carbon foams is related to continuously increasing complexity and improvement of electronic systems for defense and aerospace industries. Electrical resistivity is known as a main electrophysical property of materials, including syntactic carbon foams. The theoretical formulae were derived to calculate the influence of physical chemical properties of initial materials, composition and ratio of mixture components, the method for synthesis of syntactic carbon foams on their conductivity was used. The electrical resistivity of materials can also change significantly according to the operating conditions: ambient temperature, humidity, pollution, mechanical loads, radiation and other factors. That’s why the research that aims at the theoretical description of syntactic carbon foams depending on the above factors is extremely relevant.
