Properties of Wear Rate of Composites Made of Carbon Powder with a Matrix of Waste Glass

This paper reveals the wear rate of composite made of carbon powder and waste glass bottle as a adhesive matrix. The study was started by grinding and sifting the coconut shell carbon and waste glass bottles to reach the mesh sizes of 100, 150, 200, and 250. The two materials were mixed with the composition ratio of 70% carbon of weights and glass 30% of weights. The mixture was mixed with coal tar pitch adhesive and compacted simultaneously heated to 150 °C for 30 minutes in the mold. Furthermore, the composite samples were heated in a curing temperature pyrolysis at 1,100 °C in a vacuum furnace and held for 30 minutes. The rate of wear test results showed that the composite made of powder size of 100 mesh produced wear rate 2.77901E-05 mm 3 /Nm, composite made of powder of 150 mesh size produced wear rate 2.20224E-05 mm 3 /Nm, composite made of powder of 200 mesh size produced wear rate 1.98792E-05 mm 3 /Nm, composite made of powder with mesh size of 250 produced wear rate 1.01562E-05 mm 3 /Nm. These results indicated that the smaller the size of the powder, the lower the wear rate of the carbon-glass composite.
