Daftar Isi:
- This research is aimed to know the effect of adhesive bonding glue by adding coconut shell activated carbon powder. The percentage of 0%, 10%, 20%, 30% of carbon powder used to find out the adhesive strength and shear strength on steel joints. Steel ST 37 material used in the research has 3 mm thick, 20mm wide, and 120mm long for adhesive test and for shear test 3 mm thick, 20 mm wide , and 110mm long. Thickness of glue for this speciment is 1 mm. This research has conducted adhesive test and shear test with tensile test tool. The powder used is activated coconut shell charcoal with 1% of NaOH solution for activation in 24 hours. Results of testing show that the highest average value of adhesive test is 6,16 Mpa in the variation of 30% powderl and the lowest average value is 5,25 Mpa in the variation of 0% powder. Results of testing show that the highest average value of shear test is 13,00 Mpa in the variation of 30% powder and the lowest average value is 10,75 Mpa in the variation of 0% powder. The shape of the fracture is a mixture fracture between cohesive and adhesive. Yet,it is dominated by adhesive fracture as epoxy glue added with activated carbon powder becomes solid, that when the cracking spread through the powder, it can inhibit the cracking rate.
