- In the present study, an automotive gasoline engine piston was designed and its various structural and thermal properties were analyzed for three different materials, namely, Gray Cast Iron, Aluminum Alloy, and Epoxy Carbon Woven (230 GPa) Prepreg. The design was done on SolidWorks 2019 and the analysis was carried out on ANSYS v18.1. The lightweight of the Epoxy Carbon Woven (230 GPa) Prepreg piston as compared to the other two pistons suggests that the inertial forces are reduced for the carbon fiber material. It is also observed that the structural strength of the Epoxy Carbon Woven (230 GPa) Prepreg material piston is more than that of Gray Cast Iron, and Aluminum Alloy piston. The temperature variation for the Epoxy Carbon Woven (230 GPa) Prepreg piston is less than that of the Gray Cast Iron and Aluminum Alloy piston, thus giving it a better thermal conductivity. The heat flux for the Gray Cast Iron and Aluminum Alloy pistons is greater than that of Epoxy Carbon Woven (230 GPa) Prepreg piston. This shows that the carbon fiber piston has better resistance to thermal shock, thus suggesting that it is better than Gray Cast Iron and Aluminum Alloy, in the thermal analysis as well. However, over continuous use, the absorbed heat energy would loosen the fibers of the Epoxy Carbon Woven (230 GPa) Prepreg and hence reduce its strength. This would lead to more frequent replacement of the piston as compared to that made of Gray Cast Iron or Aluminum Alloy. Thus, the simulations suggest that Epoxy Carbon Woven (230 GPa) Prepreg is a better material for the automotive gasoline piston as compared to Gray Cast Iron and Aluminum Alloy.
