Abstract
Pengembangan airless tyre sangat penting untuk kendaraan militer untuk meminimalisir resiko fatal dari kegagalan ban konvensional. Sehingga penelitian ini dilakukan untuk menjadi studi awal terkait komposit SBR/Serat Tebu untuk aplikasi flexible spokes untuk airless tyre pada kendaraan militer. Penelitian ini bertujuan untuk mengidentifikasi efek dari penambahan komposisi dan ukuran serat tebu pada sifat mekanik dan morfologi komposit SBR/Serat Tebu. Variasi komposisi yang digunakan adalah 2,5; 5; 7,5; dan 10% dari berat dan variasi ukuran yang digunakan adalah 140, 112, dan 80μ. Komposit dikarakterisasi menggunakan FTIR, morfologi dari komposit diamati menggunakan SEM. Temperatur degradasi, kekerasan, dan kekuatan tarik diamati dengan TGA, durometer hardness shore A, dan mesin tensile. Diamati pula kemampuan serap air dari komposit. Hasil pengujian menunjukkan bahwa penambahan serat tebu hingga 2,5% akan meningkatkan sifat mekanik sementara penambahan lebih lanjut akan menurunkan sifat mekanik dari komposit. Kemudian hasil pengujian juga menunjukkan bahwa penggunaan serat tebu dengan ukuran yang semakin kecil akan semakin meningkatkan sifat mekanik dari komposit.

The development of airless tyre is very important for military vehicle in order to minimize fatal risk of conventional tire failures. Therefore this research is done to be an early study about SBR/Sugar Cane Fiber composite for the application of flexible spokes for airless tyre in military vehicle. This research aims to identify the effect of addition of sugar cane fiber composition and size on mechanical properties and morphology of SBR/Sugar Cane Fiber Composite. The variation of composition is 2,5; 5; 7,5; and 10% of weight and the size variation is 140, 112, and 80μ. The composite is characterized by FTIR, the morphology of the composite is investigated by scanning electron microscopy (SEM). Degradation temperature, hardness, and tensile strength are characterized by using thermogravimetric analysis (TGA), durometer hardness Shore A, and tensile machine, respectively. The water absorbtion of the composite is also observed. The test results show that addition of sugar cane fiber up to 2.5% will increase the mechanical properties, however, further addition will result a decrease in mechanical properties of the composite. The test result also shows that the usage of smaller sized sugar cane fiber will increase the mechanical properties of the composite.
