Turning of Composites Based on Thermally Expanded Graphite

Russian Engineering Research, 2021
The influence of the turning parameters on the surface roughness of composites based on thermally expanded graphite is considered. The dependence of the cutting force on the turning parameters is determined. A formula is proposed for the cutting force on composites based on thermally expanded graphite as a function of the selected machining conditions.

Triboengineering properties of polytetrafluoroethylene modified by thermally expanded graphite

Journal of Friction and Wear, 2008
The paper studies the effect of thermally expanded graphite upon the triboengineering, strain, and strength characteristics, as well as the thermodynamic and structural parameters of polytetrafluoroethylene as dependent on its concentration. Introduction of graphite filler was found to lead to improvement of compressive strength, elasticity modulus ...

Free graphene films obtained from thermally expanded graphite

Technical Physics, 2010
A method of obtaining free graphene films using intercalation and subsequent thermal expansion of crystalline graphite is suggested. Thermally expanded graphite prepared by microwave irradiation is examined under a scanning electron microscope. It is found that it contains fragments of free graphene films.

Synthesis and studies of properties of graphite oxide and thermally expanded graphite

Protection of Metals and Physical Chemistry of Surfaces, 2014
Graphite oxide is synthesized using various reaction parameters. Stagewise evaluation of graphite oxidation dynamics in the course of synthesis is carried out using the method of sample collection and thermogravimetric analysis. Thermally expanded graphite with high texture characteristics was obtained from graphite oxide.

Thermal conductivity and mechanical properties of expanded graphite

Inorganic Materials, 2009
The thermophysical and mechanical properties of compacted expanded graphite (EG) were studied. The experimental results were interpreted with application of similarity theory. The compacted EG critical density corresponding to the observed jump in the thermal conductivity coefficient and elasticity modulus was shown to depend on the expandable graphite

Deformation of materials based on thermally expanded graphite

Powder Metallurgy and Metal Ceramics, 1998
Strain and strength in uniaxial compression have been examined for specimens with various densities made by uniaxial pressing of thermally expanded graphite powders, which have been produced by the heat treatment of intercalated graphite compounds. Low-density graphite specimens formed at 600°C have the highest strain resistance.
