Abstract

The influence of expanded graphite (EG) on the thermal and rheological properties of shear thickening fluids (STF) based on silica powder with poly (propylene glycol) matrix was studied. Capturing the benefits of this non-Newtonian system in a fabricated material allows producing advance flexible protectors. However, in order to provide high protection potential in response to an external force, it is necessary to minimize negative effect of temperature on STF. The doping additives reduce the unfavorable effect of temperature increase on shear thickening flow during an impact through faster heat exchange and return to the initial state, characterized by the highest protective potential. EG in different volume fractions (0.10% - 5.00%) as a partial substitution of STF and SiO2 was added to studied systems and measured at temperatures in the range from 25.0 to 50.0°C. The dilatant effect of fluids increased by 580% for 5% volume fraction EG at 50.0°C.
