Development of technology for the production of thermally conductive carbon foams using microspheres and pitches

The technological process of obtaining thermally conductive carbon foams based on microspheres and pitches, including the stages of mixing the initial components, pressing the mixture of components, obtaining semi-finished "green" foam, low-temperature carbonization, carbonization, high-temperature heat treatment, pyro-compaction, mechanical processing has been developed. It is shown that the structure of the resulting foam is characterized by a lower content of voids, the layered structure of the walls of microspheres. The obtained values of thermophysical and physical-mechanical characteristics provide the possibility to use the foams for work in extreme condition

Influence of the composition and synthesis technology on the physical chemical and performance properties of foam materials

The comparative analysis of a combination of primary properties of foam materials made using the different starting components and technologies was made. According to the review of the literature and analysis of the experimental data, the paper shows a significant influence the starting components and process approaches have on the properties of the materials. The comparison of material properties revealed that the properties of syntactic carbon foams are higher than those of other porous materials, including metal foams, and comply with the specification

Study of the influence of synthesis technologies on the properties of syntactic carbon foams

The paper studied the influence of starting components and operating conditions of synthesis processes on the performance properties of syntactic carbon foams. The studies determined the behavior and ranges of hardness, ultimate compressive strength, apparent density, and thermal conductivity of foams made by template carbonization and using carbon microballoons, depending on heat treatment temperature. They determined the influence of a volatile blowing agent (sodium chloride) with wide and narrow fraction on a change in the studied properties of syntactic carbon foams
