Abstract
In the modern automotive industry, the development of natural fiber-based composite materials has become a focus to produce lightweight, strong, and environmentally friendly vehicle components. One potential material is ramie fiber (Boehmeria nivea), which offers high mechanical properties and is biodegradable. Conventional car dashboards made of metal or plastic have several weaknesses, such as high weight, heat conductivity, and low corrosion resistance. This research aims to determine the optimum percentage of ramie fiber in a resin composite, and to evaluate the feasibility of its use as an alternative car dashboard material through simulation. The methods used include making composite specimens with the hand lay-up technique, mechanical properties testing using a tensile test in accordance with ASTM D638 Type I standards, and simulation of loading on the car dashboard design using SolidWorks software. The results of the tests and simulations show that the composite specimens have good tensile strength. Stress simulation analysis shows that the maximum stress occurring on the dashboard (0.9101 MPa) is well below the material's yield strength limit (24.47 MPa). The maximum displacement that occurs is very small (0.09890 mm) and is within the material's elastic tolerance. Furthermore, a minimum Factor of Safety (FoS) value of 26.89 indicates that the dashboard design has a very high safety margin against structural failure. It is concluded that ramie-resin composite material is highly potential and suitable for use as an alternative material for car dashboard applications. Keywords : Composite, Ramie Fiber, Tensile Test, SolidWorks, Dashboard. Dalam industri otomotif modern, pengembangan material komposit berbasis serat alam menjadi fokus untuk menghasilkan komponen kendaraan yang ringan, kuat, dan ramah lingkungan. Salah satu material yang berpotensi adalah serat rami (Boehmeria nivea), yang menawarkan sifat mekanis tinggi serta sifat biodegradable. Dashboard mobil konvensional berbahan logam atau plastik memiliki beberapa kelemahan, seperti berat yang tinggi, konduktivitas panas, dan ketahanan korosi yang rendah. Penelitian ini bertujuan untuk menentukan persentase optimum serat rami dalam komposit resin, serta mengevaluasi kelayakan penggunaannya sebagai alternatif bahan dashboard mobil melalui simulasi. Metode yang digunakan meliputi pembuatan spesimen komposit dengan teknik hand lay-up, pengujian sifat mekanis menggunakan uji tarik sesuai standar ASTM D638 Tipe I, serta simulasi pembebanan pada desain dashboard mobil menggunakan perangkat lunak SolidWorks. Hasil pengujian dan simulasi menunjukkan bahwa spesimen komposit memiliki kekuatan tarik yang baik. Analisis simulasi tegangan menunjukkan bahwa tegangan maksimum yang terjadi pada dashboard (0,9101 MPa) jauh di bawah batas kekuatan luluh material (24,47 MPa). Perpindahan (displacement) maksimum yang terjadi sangat kecil (0,09890 mm) dan berada dalam batas elastis material. Selain itu, nilai Factor of Safety (FoS) minimal sebesar 26,89 menunjukkan bahwa desain dashboard memiliki margin keamanan yang sangat tinggi terhadap kegagalan struktural. Disimpulkan bahwa material komposit serat rami-resin sangat potensial dan layak digunakan sebagai bahan alternatif untuk aplikasi dashboard mobil. Kata kunci : Komposit, Serat Rami, Uji Tarik, SolidWorks, Dashboard Mobil.
