ANALISIS KETANGGUHAN ANTARA BAJA ST 37 DAN ST42 DENGAN KETEBALAN DAN VARIASI LAPISAN KARBON FIBER UNTUK KERANGKA MOBIL LISTRIK

Abstrak

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