Abstract

Penelitian tentang material alam sebagai pengganti material asbes dalam komposit material gesek kampas rem motor terus mengalami peningkatan. Material dalam kategori biomassa sebagai reinforcement komposit agar mendapatkan karakteristik material yang sesuai standar material gesek kampas rem motor. Penelitian ini bertujuan untuk mengetahui pengaruh fraksi volume sekam padi, aluminium oksida, dan besi oksida terhadap sifat mekanik dari spesimen komposit material gesek kampas rem. Proses pembuatan spesimen menggunakan metode hand lay-up dengan fraksi volume material epoksi (100 wt% dan 50 wt%), sekam padi (0 wt% dan 20 wt%), aluminium oksida (25 wt% dan 15 wt%), dan besi oksida (25 wt% dan 15 wt%). Pada penelitian ini, didapatkan pengaruh fraksi volume sekam padi, aluminium oksida, dan besi oksida terhadap sifat mekanik dari spesimen komposit material gesek kampas rem motor yaitu dapat meningkatkan nilai dari masing-masing hasil pengujian. Sehingga, dapat disimpulkan bahwa penggunaan material epoksi 50 wt%, sekam padi 20 wt%, aluminium oksida 15 wt%, dan besi oksida 15 wt% membuat ikatan antar partikel spesimen komposit material gesek kampas rem motor semakin baik dikarenakan kandungan silikanya yang tinggi. Oleh karena itu, didapatkan spesimen komposit material gesek kampas rem sepeda motor dengan sifat mekanik yang baik sesuai standar SNI nomor 09-0143-1987 dan SAE J661-1997.

Abstract

Failure in the results of making the crucible is cracking and even deformation. Cracks that occur can cause fluid leakage when melting so that it disrupts the casting process. The quality of the crucible can be influenced by factors including the selection of constituent materials, particle size, the amount of pressure, and the length of the firring process of heat treatment and cooling in the furnace. This study aims to determine the effect of heating rate on crucible made from clay and kaolin and molasses as a binder. With the treatment of different heating rates in the firring process, namely 3 ℃ / min, 4 ℃ / min, 5 ℃ / min, 6 ℃ / min, and 7 ℃ / min.  The composition of the materials used is 40% clay, 40% kaolin, and 5% molasses and 15% water as the total mass. The process of making specimens begins with crushing clay, sieving clay 100 mesh. Mixing process using twin screw extruder machine repeatedly for 45 minutes. Molded cylindrical size 20 x 20 mm, free air drying for 8 days, firring process at 1000 ℃ holding time 1 hour. The results showed that the difference in heating rate did not affect the change in chemical elements but the best heating rate was at 3℃/min showing a denser morphology, density value of 1.62 g/cm3, porosity value of 23%, and Vickers hardness value of 20.43 HVN.
