Zusammenfassung:This study aims to know the effect of resin and hardener ratio of epoxy matrix on the manufacture of carbon fiber composite materials using the VARTM printing method on the mechanical properties of carbon fiber composites and to know the best formulation between resin and hardener used in the VARTM printing methods. This research is an experimental study, with the subject being a carbon fiber composite test sample made using the composition of resin and hardener epoxy matrix ratios that were varied and printed using the VARTM method. The resin and hardener ratios of an epoxy matrix are 60%:40%, 70%:30%, and 80%:20%. Processing and analysis of test data using descriptive statistical methods. The results of this study indicate carbon fiber composites printed by the VARTM method, the 70%:30% ratio, in higher tensile and flexural strengths of 10.8% and 35. 7% respectively, compared to the ratio of 60%:40%, while the 80%:20% resin and hardener ratio, a decrease in tensile and flexural strength respectively by 21% and 45.3% when compared to the 60%:40 % ratio. In addition, the 60%:40% ratio is the lowest density compared to 70%:30% and 80%:20% ratios. Next, the best formulation of resin and hardener ratio to increase the strength of carbon fiber composites printing using the VARTM method is 70%:30%. In contrast, for the density value, the best formulation is 60%:40%.
