Abstract
Pengembangan Unmanned Aerial Vehicle (UAV) mendorong kebutuhan material rangka yang ringan, kuat, dan berkelanjutan. Carbon fiber reinforced polymer memiliki performa mekanik tinggi, namun membutuhkan energi produksi besar sehingga diperlukan alternatif berbasis sumber daya terbarukan. Penelitian ini bertujuan menganalisis pengaruh jenis dan komposisi filler mikroserat alam terhadap karakteristik komposit berbasis bioresin hasil pencetakan 3D untuk aplikasi rangka multirotor UAV. Komposit dibuat menggunakan mikroserat sabut kelapa, eceng gondok, dan sekam padi dengan variasi komposisi 0,4; 0,8; 1,2; dan 1,6 wt% melalui teknologi Stereolithography (SLA). Karakterisasi dilakukan menggunakan FTIR, SEM, viskositas, densitas, water absorption, kekuatan tarik, dan kekerasan. Hasil penelitian menunjukkan penambahan filler mikroserat alam memengaruhi morfologi, interaksi antarmuka, dan sifat mekanik komposit. Komposisi optimum 1,2 wt% menghasilkan tensile strength sebesar 53,48 MPa pada sabut kelapa (meningkat 21,38% dari 44,06 MPa), 48,08 MPa pada eceng gondok (meningkat 9,12%), dan 50,14 MPa pada sekam padi (meningkat 13,80%). Penambahan filler berlebih menyebabkan aglomerasi dan porositas yang menurunkan performa mekanik. Komposit berbasis bioresin dengan filler mikroserat alam berpotensi dikembangkan sebagai material ringan dan ramah lingkungan untuk rangka multirotor UAV.

The development of Unmanned Aerial Vehicle (UAV) technology has increased the demand for lightweight, strong, and sustainable frame materials. Carbon fiber reinforced polymer exhibits excellent mechanical performance; however, its production requires high energy consumption, encouraging renewable-based material alternatives. This study aimed to analyze the effects of natural microfiber filler type and composition on bioresin-based composites fabricated using 3d printing technology for multirotor UAV frame applications. The composites were fabricated using coconut coir, water hyacinth, and rice husk microfibers with filler compositions of 0.4, 0.8, 1.2, and 1.6 wt% through the Stereolithography (SLA) process. Characterization was conducted through FTIR, SEM, viscosity, density, water absorption, tensile strength, and hardness tests. The results showed that natural microfiber addition affected morphology, interfacial interaction, and mechanical properties. The optimum filler composition of 1.2 wt% produced tensile strengths of 53.48 MPa for coconut coir microfiber (21.38% increase from 44.06 MPa), 48.08 MPa for water hyacinth microfiber (9.12% increase), and 50.14 MPa for rice husk microfiber (13.80% increase). Excessive filler addition resulted in agglomeration and porosity, reducing mechanical performance. Bioresin-based composites reinforced with natural microfibers showed potential as lightweight and sustainable materials for multirotor UAV frame applications.
