Abstract

Penelitian ini mengevaluasi pengaruh jumlah lapisan komposit terhadap performa mekanik tangki hidrogen tipe IV dengan menggunakan liner ABS dan komposit E-glass/epoxy melalui simulasi metode elemen hingga (FEM) di ANSYS. Variasi jumlah lapisan menunjukkan bahwa peningkatan lapisan secara umum mampu mengurangi deformasi dan meningkatkan kekakuan struktur. Namun, tidak semua peningkatan memberikan dampak signifikan, sehingga diperlukan pertimbangan efisiensi material. Konfigurasi dengan jumlah lapisan menengah terbukti memberikan keseimbangan terbaik antara kekuatan struktur dan efisiensi penggunaan material. Temuan ini memberikan dasar pertimbangan dalam perancangan tangki hidrogen yang ringan, kuat, dan aman untuk aplikasi kendaraan berbasis fuel cell.
