Abstract

Perkembangan teknologi terjadi secara pesat seiring dengan bertambahnya waktu, contohnya pada perkembangan teknologi drone atau (UAV) unmanned aerial vehicle. Drone merupakan teknologi yang dapat membantu kehidupan manusia di berbagai sektor seperti media ataupun militer. Namun seiring perkembangan di bidang drone dan komponen-nya yang pesat, penelitian mengenai pembuatan atau manufaktur propeller drone quadcopter dari bahan komposit di Institut Teknologi Sepuluh Nopember masih belum ada berdasarkan hasil pencarian di data repository Institut Teknologi Sepuluh Nopember. Pada penelitian ini kami mempelajari performa mekanik dan menganalisa spesimen komposit laminat dengan susunan carbon fiber, fiberglass, dan hybrid serta propeller drone quadcopter hybrid dengan susunan yang sama dengan spesimen komposit laminat yaitu lapisan susunan C/G/C/G/C/G/C dan G/C/G/C/G/C/G. Pada penelitian ini spesimen komposit laminat dibentuk sesuai dengan standardisasi ISO-179 dan ASTM D3039-17 serta dibuat dengan metode vacuum resin infusion, untuk propeller drone quadcopter dengan metode hand lay-up. Pengujian tensile, pengujian impact, dan pengujian cantilever bending dilakukan untuk mengetahui performa mekanik dari spesimen komposit laminat dan propeller drone quadcopter dengan susunan hybrid. Pada penelitian ini, pengujian tensile dilakukan pertama pada spesimen komposit carbon fiber dan fiberglass, dimana spesimen komposit dengan jenis carbon fiber memiliki rata – rata nilai load, stress, strain, dan modulus young lebih besar dibanding fiberglass. Untuk pengujian tensile dari spesimen variasi lapisan susunan G/C/G/C/G/C/G mempunyai nilai rata – rata yang lebih tinggi untuk load, stress, strain, tetapi mempunyai nilai yang lebih rendah untuk modulus young dibanding spesimen C/G/C/G/C/G/C. Pada pengujian impact spesimen variasi lapisan susunan G/C/G/C/G/C/G mempunyai nilai energi serap dan energi impact yang lebih besar dibanding C/G/C/G/C/G/C. Pengujian cantilever bending dilakukan dengan pengaturan displacement 10mm dan didapatkan hasil spesimen C/G/C/G/C/G/C lebih mampu menahan load lebih tinggi dibanding spesimen G/C/G/C/G/C/G. Pengamatan makroskopis juga dilakukan untuk mengetahui patahan dan kegagalan yang terjadi pada spesimen komposit laminat hybrid yang diuji impact dan tensile. Kegagalan berupa delaminasi dan fiber pull-out yang terjadi pada spesimen tensile mempengaruhi nilai stiffness dan load-drop pada spesimen tensile yang diuji. Sedangkan pada spesimen impact terjadi kegagalan delaminasi dan fiber fracture pada sisi compression dan tension juga mempengaruhi nilai energi serap dari spesimen yang diuji impact.

Rapid technological advancements have been occurring over time, such as in the development of drone technology, also known as Unmanned Aerial Vehicles (UAVs). Drones are technological innovations that have the potential to assist humans in various sectors, including media and the military. However, despite the rapid progress in the field of drones and their components, there is still a lack of research on the manufacture of quadcopter drone propellers using composite materials at the Sepuluh Nopember Institute of Technology, based on the search results in the institute's data repository. In this study, the researchers focused on investigating the mechanical performance and analyzing composite laminate specimens with different compositions, such as carbon fiber, fiberglass, and hybrid structures, as well as hybrid quadcopter drone propellers with similar arrangements of C/G/C/G/C/G/C and G/C/G/C/G/C/G layers as in the composite laminate specimens. The composite laminate specimens were formed following the ISO-179 and ASTM D3039-17 standards and were made using the vacuum resin infusion method, while the quadcopter drone propellers were made using the hand lay-up method. Various tests were conducted to assess the mechanical performance of the composite laminate specimens and the hybrid quadcopter drone propellers. These tests included tensile testing, impact testing, and cantilever bending testing. Tensile testing was carried out first on the carbon fiber and fiberglass composite specimens. It was observed that the carbon fiber composite specimens had higher average values of load, stress, strain, and young's modulus compared to the fiberglass composite specimens. The G/C/G/C/G/C/G arrangement in the composite laminate specimens showed higher average values for load, stress, and strain but lower values for young's modulus compared to the C/G/C/G/C/G/C arrangement. In impact testing, the G/C/G/C/G/C/G arrangement exhibited higher values for energy absorption and impact energy compared to the C/G/C/G/C/G/C arrangement. Cantilever bending testing was performed with a 10mm displacement setting, and the results showed that the C/G/C/G/C/G/C arrangement was better able to withstand higher loads compared to the G/C/G/C/G/C/G arrangement. Macroscopic observations were also carried out to determine the fractures and failures that occurred in the hybrid composite laminate specimens during impact and tensile testing. Failures such as delamination and fiber pull-out affected the stiffness and load-drop values of the tensile-tested specimens. Additionally, in the impact-tested specimens, delamination and fiber fracture occurred on the compression and tension sides, which also influenced the energy absorption values of the specimens. In conclusion, this research contributes valuable insights into the mechanical properties and performance of composite laminates and hybrid quadcopter drone propellers. The findings could potentially pave the way for further advancements and applications in the field of drone technology, especially concerning the use of composite materials to improve their efficiency and capabilities.
