Investigations of Thermal Conductivity for Palm Fronds and Egg Shell Filled Epoxy Composites

Thermal conductivity has been improved by using epoxy reinforcement techniques extensively.Thus, combining natural materials (egg shell particles and palm fronds) to epoxy is the focus of this work's reinforcement.Different percentages of particles (4, 6, 8 and 10%) were used the effect of adding egg shell (ES) and palm fronds (PF) particles to the epoxy resin has been studied during thermal conductivity tests under natural conditions and immersion in an acid solution (HCl) for a period of (14 days) with normality (0.3 N).Thermal conductivity test results under natural conditions (N.C) showed that epoxy reinforced with palm fronds particles (EP/PF) increased with increasing weight percent (wt%), but thermal conductivity values (K) for egg shells particles (EP/ES) decreased with increasing weight percentage, while immersion in acidic solution (HCl) exceeds the (K) values after immersion more than the value in (N.C).
