Abstract
Peluru frangible merupakan peluru yang akan hancur saat menghantam permukaan material. Material utama pada peluru frangible adalah Cu-Sn. Pada penilitian kali ini, logam Sn akan diganti oleh Vinyl Ester dalam proses pembuatan peluru frangible. Proses pembuatan peluru frangible menggunakan metode casting/pengecoran. Serbuk tembaga yang digunakan akan diproses menggunakan ball mill. Komposit yang akan dibuat memiliki 4 variasi komposisi serbuk tembaga, 20%, 30%, 40%, 50%. Komposit Cu/VE ini akan diuji menggunakan uji kekerasan, uji FTIR, uji densitas, uji tekan, dan uji morfologi menggnakan SEM. Hasil pengujian kekuatan tekan mengalami peningkatan pada material serbuk Cu yang melalui proses ball mill. Kekuatan tekan mengalami peningkatan sebesar 78%. Peningkatan ini cukup baik untuk diaplikasikan pada peluru frangible. =====================================================================================Frangible bullet is a type of bullet that will rupture when it hits the surface of a material. The main material composing frangible bullet are Cu-Sn. In this study, Sn metal will be replaced by Vinyl Ester in the process of making frangible bullets. The process of making frangible bullet in this study use casting method. The copper powder used will be processed using a ball mill. The composite have 4 variations of copper powder composition, 20%, 30%, 40%, 50%. Cu / VE composite will be tested using hardness test, FTIR test, density test, compression test, and morphology test using SEM. Test results of compressive strength have increased on Cu powder material through ball mill process. The compressive strength has increased by 78%. This increase is quite applicable to frangible bullets.
