Analyzing the toughness of St 37 and St 42 with variations in the thickness of the carbon fiber layer forelectric car applications, as well as proving that there is an increase in strength in the material in terms oftoughness. Impact testing with variations in the thickness of the carbon layer and adhesion of carbon fiberusing resin. The test results show that the toughness of St 37 with variations in carbon fiber layers canincrease toughness, if without using a carbon fiber layer it shows the lowest toughness value. Thus thethickness of the carbon fiber layer affects the toughness of St 37. The thicker the layer is given, the higherthe toughness value obtained. So that by coating with carbon fiber the toughness value can exceed St 42 Keywords: carbon fiber, toughness, impact
