Abstract
Carbon nanotube merupakan material allotropi carbon yang memiliki sifat mekanik, thermal dan elektrik cukup baik. Saat ini para peneliti masih banyak menganalisa kebutuhan sifat mekanik yang tepat untuk dapat diterapkan lebih diberbagai bidang. Ukurannya yang nano membuat sulitnya pengujian untuk menganalisa sifat dan perilaku CNT. Sehingga diperlukan adanya simulasi komputasi untuk menyederhanakan penelitian. Hasil simulasi dibuat untuk menganalisa sifat mekanik berupa modulus elastisitas SWCNT dengan membandingkan variasi struktur tipe zigzag dan armchair menggunakan software ANSYS 17.1 Mechanical APDL. Hasil simulasi juga digunakan untuk menganalisa pengaruh diameter, ketebalan, dan aspek rasio terhadap nilai Young’s modulus SWCNT. Diperoleh bahwa struktur yang sesuai untuk aplikasi yang membutuhkan tingkat kelenturan yang tinggi akibat pembebanan bending dan buckling adalah struktur armchair. Dimana semakin besar diameter single walled carbon nanotube maka nilai Young’s modulusnya. Semakin meningkat. Dan semakin tinggi aspek rasio dan ketebalan struktur SWCNT maka semakin rendah nilai Young’s modulusnya. =======================================================================================================
Carbon nanotube is a carbon allotropy which has good mechanical, thermal and electrical properties. Currently the researchers are still analyzing the right properties for their right properties in composites. Those Nano size make CNT rather hard to analyze the behavior of CNTs in form of experiment. A simulation is needed to simplify the research. Therefore, this study was made to analyze the simulation results of SWCNT’s modulus elasticity by comparing structural variations of the zigzag and armchair types using finite element method software ANSYS 17.1 Mechanical APDL. Simulation result used for analyzing diameter and aspect ratio effect on the structure of SWCNT. The suitable structure which need high elasticity caused by bending and buckling loading is armchair type of SWCNT. The highest diameter of SWCNT, the higher Young’s modulus value is. And the higher aspect ratio and the thickness structure of SWCNT, the lower Young’s modulus had.
