Abstract

In this study, researchers made motorcycle brake pads using natural fiber composite materials and environmentally friendly artificial fibers with several variations in material composition to determine the value of safety, wear, and coefficient of friction. The materials used in this study were flax fiber, fiberglass, 40,50, and 60 brass mesh powders, calcium carbonate, barium sulfate, and polyester resin and catalyst as the matrix. Then tap the remnants with a load of 16 kg for 3 hours with dry test, air, oir, salt water, and brake fluid and then wear and coefficient of friction calculated, and debated using the Durometer standard ASTM D2240. From the testresult obtained the highest value obtained in Pasaran brake linings with a value of 86,7 HD, while the hardness that pushed Pasaran lining was obtained in a 60 mesh variation brake lining with a hardness value of 84,6 HD. The results of the wear evaluation show the lowest brake pad wear value occurs in the Pasaran canvas variation, while the next lowest wear occurs in the 60 mesh brass variation with a value 81,25 mm3/hour dry conditions, 51,63 mm3/hour air condition, 59,37 mm3/hour oil condition, 46,87 mm3/hour salt water condition, and 69,37 mm3/hour in brake fluid conditions. The result of the data obtained by the highest coefficient of friction were obtained by variations of Pasaran brake linings, while the result obtained were brake pads of brass mesh 60 variation with values 0f 0,6226, 0,5725, 0,5383, 0,5754,and 0,5718. In the micro photo after the 50 mesh friction test breaks the cohesive bond, while the 40 and 60 mesh fixed the cohesive bond and the adhesive. From the above discussion it can be denied that the large size of powder used determines the value of struggle, wear, and also the coefficient of friction.
