Abstract

Kampas rem merupakan bagian terpenting dari sistem pengereman sebagai fitur keamanan kendaraan bermotor, yang berfungsi untuk memperlambat maupun menghentikan laju kendaraan. Pada umumnya kampas rem terbuat dari material non-asbestos dan asbestos yang mengandung zat karsinogen. Kampas rem non-asbestos memiliki beberapa kelebihan yaitu ramah lingkungan, tidak berbunyi, memiliki kemampuan tahan panas dan tahan gesek yang baik. Kampas rem harus memenuhi nilai koefisien gesek (μ) dan kecepatan keausan (wear) yang rendah agar memenuhi persyaratan sistem pengereman pada kendaraan bermotor. Nilai kekerasan juga perlu dipelajari lebih lanjut, karena jika kampas rem sangat keras akan mempengaruhi kinerja disc rotor. Lebih lanjut, densitas dan porositas kampas rem perlu diketahui untuk mendapatkan kampas rem yang memenuhi standar kampas rem kendaraan bermotor. Penelitian mengenai kampas rem non-asbestos berbahan komposit serat alam telah banyak dilakukan, namun perlu dilakukan studi kelayakan lebih lanjut. Hal ini dibutuhkan untuk mengetahui kemampuan kampas rem berbahan komposit serat alam berdasarkan standar uji kampas rem kendaraan bermotor.
Pada penelitian ini dilakukan pembuatan kampas rem komposit dengan penguat serat kelapa yang diberi perlakuan alkalisasi kemudian dicampur dengan matriks resin epoxy dengan penambahan alumina dan magnesium oksida sebagai friction modifier. Kampas rem komposit berpenguat serat kelapa ini kemudian dilakukan pengujian kekerasan, laju keausan, koefisien gesek, densitas, dan porositas untuk mengetahui karakteristik mekaniknya.
Hasil dari pengujian didapatkan nilai uji antara kampas rem komposit dengan kampas rem pembanding berturut-turut untuk kekerasan (97,25 HD dan 99,05 HD), laju keausan spesifik (2,99 x 10^-7 cm^3/Nm dan 1,77 x 10^-7 cm^3/Nm), koefisien gesek (0,41 dan 0,43), densitas (1,93 gr/cm^3 dan 2,42 gr/cm^3), porositas (19,72% dan 11,89%). Kampas rem komposit dengan komposisi serat kelapa sebagai penguat dan resin epoxy sebagi matriks dengan penambahan friction modifier berupa alumina dan MgO dapat menunjukkan karakteristik mekanik kampas rem komposit yang sebanding dengan kampas rem pasaran.

Brake pad is the most important part of the braking system as a vehicle safety feature, which functions to slow down or stop the motorized vehicle. Generally, brake pads are made of non-asbestos and asbestos materials that contain carcinogens. Non-asbestos brake pads have several advantages, which are environmentally friendly, not noisy, and have a good temperature resistance and friction resistance. Brake pads must qualify the value of the coefficient of friction (μ) dan has low wear also to qualify braking system requirements on motorized vehicles. Hardness values also need to be studied further, because if the brake pads is very hard it will affect the disk rotor's performance. Furthermore, the density and porosity of the brake pads need to be known to get brake pads that qualify the standards of motorized brake pads. Research on non-asbestos brake pads made from natural fiber composites has been carried out, but further feasibility studies are needed. This is to determine the ability of brake pads made from natural fiber composites based on test standards for motorized brake pads.
In this research, the composition of manufacture of composite brake pads consists of coconut fiber which is given alkaline treatment as reinforcement then mixed with an epoxy resin as a matrix with the filler addition of alumina and magnesium oxide as a friction modifier. The composite brake pads was then tested for hardness, wear rate, coefficient of friction, density and porosity to determine the mechanical characteristics.
The results of the tests between composite brake pads with comparative brake pads with successive values for hardness (97.25 HD and 99.05 HD), specific wear rates (2.99 x 10^-7 cm^3/Nm and 1.77 x 10^-7 cm^3/Nm), coefficient of friction (0.41 and 0.43), density (1.93 gr/cm^3 and 2.42 gr/cm^3), porosity (19.72% and 11.89%). The composite brake pads with the composition of coconut fiber as reinforcement and epoxy resin as a matrix with the alumina and MgO a friction modifier filler can show the mechanical characteristics of composite brake pads that are comparable with brake pads on the market.
