Abstract
Brake pads are one of the components in a vehicle that function to reduce and stop the vehicle's speed. To reduce air pollution caused by dust from brake pads, environmentally friendly materials such as eggshells and bamboo fibers are used. Physical and tribological testing was conducted on the brake pads by simulating oil exposure for 7, 14, and 21 days, with bamboo fibers and eggshell particles subjected to three variations in volume fraction to determine the optimal variation. Before the manufacturing process, the bamboo fibers were treated with 5% alkali for 2 hours. A cold press machine with a pressure of 5 MPa was used for 75 minutes, followed by an oven for curing at 150℃ for 1 hour. The finishing process used sandpaper to achieve a smooth surface, and the specimens were then immersed in oil. Based on the tests conducted, it was found that the FCT specimens exhibited the best overall performance when measured using the multi-response performance index. The average actual density was 1.674 g/cm3, porosity 21.835%, oil absorption of 0.819%, friction coefficient during oil immersion of 0.440 after 7 days, 0.460 after 14 days, and 0.473 after 21 days, and specific abrasiveness of 2,699 × 10−6 mm2/kg .

| Additional Information: | Kampas rem merupakan salah satu komponen pada kendaraan yang berfungsi mengurangi dan menghentikan laju kendaraan. Untuk mengurangi polusi udara akibat debu dari kampas rem, maka digunakanlah material yang ramah lingkungan seperti cangkang telur dan serat bambu. Pada kampas rem dilakukan pengujian fisik dan tribologi dengan memberikan simulasi paparan oli selama 7, 14, dan 21 hari dimana pada serat bambu dan partikel cangkang telur diberikan 3 variasi fraksi volume untuk menemukan variasi terbaik. Sebelum dilakukan proses manufaktur, serat bambu diberikan perlakuan alkali 5% selama 2 jam. Digunakan mesin cold press dengan tekanan 5 MPa selama 75 menit dan oven untuk proses curing bertemperatur 150℃ selama 1 jam. Proses finishing menggunakan amplas gerinda untuk mendapatkan permukaan yang rata dan selanjutnya spesimen direndam pada oli. Berdasarkan pengujian yang dilakukan, diketahui jika spesimen FCT memiliki performa terbaik jika diukur secara keseluruhan dengan multi response performance index. Didapatkan densitas aktual rata-rata 1,674 g/cm3, porositas 21,835%, oil absorption 0,819%, koefisien gesek pada perendaman oli 7 hari sebesar 0,440, 14 hari sebesar 0,460, 21 hari sebesar 0,473, dan spesifik abrasif 2,699 × 10−6 mm2/kg. | ||||||
