Abstract
Penelitian ini bertujuan untuk menganalisis dampak radiasi ultraviolet (UV) terhadap sifat mekanik, sifat fisik, dan morfologi komposit syntactic foam epoksi/silika microballoon yang diaplikasikan sebagai komponen floater pada pesawat terbang amphibious. Penelitian ini dilakukan dengan merancang variasi material dengan persentase yang berbeda dari epoksi, hardener, dan silika. Selain itu, dilakukan perlakuan radiasi UV buatan dan alami dengan durasi yang bervariasi pada setiap sampel. Pengujian karakterisasi komprehensif dilakukan untuk memahami perubahan sifat material tersebut. Termasuk di dalamnya adalah pengujian viskositas, kekuatan tarik, analisis morfologi SEM-EDS, pengukuran densitas, analisis DSC, kekuatan lentur, tingkat kekerasan, analisis FTIR, TGA, UV-VIS, dan ketahanan terhadap air pada setiap sampel. Hasil penelitian menunjukkan adanya perubahan yang signifikan dalam sifat-sifat material komposit yang terkena radiasi UV. Sampel-sampel yang terpapar radiasi UV pada rentang tertentu menunjukkan peningkatan yang konsisten dalam beberapa sifat mekanik, seperti peningkatan kekuatan tarik maksimum dari 20,27 MPa pada sampel tanpa paparan menjadi 81,11 MPa setelah 400 jam paparan UV. Kekuatan lentur maksimum juga meningkat dari 36,83 N/mm² menjadi 50,02 N/mm² setelah 400 jam paparan UV alami. Selain itu, sifat fisik seperti ketahanan terhadap air dan perubahan densitas menunjukkan peningkatan densitas dari 1,0073 g/cm³ menjadi 1,0129 g/cm³ setelah paparan 400 jam UV buatan. Analisis morfologi membantu dalam memahami struktur internal yang terpengaruh oleh radiasi UV. Penelitian ini memberikan wawasan mendalam tentang pengaruh perlakuan radiasi UV terhadap komposit epoksi/silika microballoon dan implikasinya terhadap aplikasi pada komponen floater pesawat terbang amphibious

This study aims to analyze the impact of ultraviolet (UV) radiation on the mechanical properties, physical properties, and morphology of syntactic foam epoxy/silica microballoon composites applied as floater components on amphibious aircraft. This study was conducted by designing material variations with different percentages of epoxy, hardener, and silica. In addition, artificial and natural UV radiation treatments were carried out with varying durations on each sample. Comprehensive characterization testing was carried out to understand the changes in material properties. This includes testing viscosity, tensile strength, SEM-EDS morphology analysis, density measurement, DSC analysis, flexural strength, hardness level, FTIR analysis, TGA, UV-VIS, and water resistance on each sample. The results showed significant changes in the properties of the composite material exposed to UV radiation. Samples exposed to UV radiation at certain ranges showed consistent increases in several mechanical properties, such as an increase in maximum tensile strength from 20.27 MPa in samples without exposure to 81.11 MPa after 400 hours of UV exposure. The maximum flexural strength also increased from 36.83 N/mm² to 50.02 N/mm² after 400 hours of natural UV exposure. In addition, physical properties such as water resistance and density change showed an increase in density from 1.0073 g/cm³ to 1.0129 g/cm³ after 400 hours of artificial UV exposure. Morphological analysis helps in understanding the internal structure affected by UV radiation. This study provides an in-depth insight into the effect of UV radiation treatment on epoxy/silica microballoon composites and its implications for applications in floater components of amphibious aircraft
