The particle size effect of Halexylon Salicornicum on thermal conductivity and dielectric constant of polyester resins- Halexylon Salicornicum composites

Abstract

Iraq is home to the Halexylon Salicornicum plant (HS). This study modifies thermal conductivity and dielectric constant of unsaturated polyester resin using HS as filler (UPE). Different HS filler particle sizes, including 6.5 mm (raw HS), 1.18mm, 250 m, 125 m, 75 m, and 50 m, are used to create HS- UPE composites. HS filler loading levels (1, 3, 5, 7, 10, 15, 20 and 25) (wt percent). All HS- UPE composites' thermal conductivity and dielectric constant are investigated. Study is done on how changes in frequency (from 500 Hz to 1 MHz) affect the dielectric constant of all composites. The thermal conductivity of HS- UPE composites falls as the concentration of HS filler increases and particle size reduces; it is at its lowest level at 25% weight. At 50 m particle size, the impact of particle size on heat conductivity of composites is clearly visible. When HS filler concentration rises and particle size falls, the dielectric constant of HS- UPE composites increases; it reaches its maximum value at 25% wt and 50m RH particle. On 50 m RH-RTV silicone composites, frequency variation has little impact.
