Abstract

U ovom završnom radu provedena je izrada i analiza kompozitnih kalota, odnosno njihovo balističko testiranje u funkciji kacige za vojnu industriju.
Teorijski dio obuhvaća uvod u kompozitne materijale, te njihovu podjelu, svojstva i primjenu. Pobliže su opisana UHMWPE vlakna zbog svojih specifičnih karakteristika i širokog spektra upotrebe. Istaknuti su načini izrade polimernih kompozita, te svojstva zbog kojih su ovi materijali adekvatni za antibalističku zaštitu.
U eksperimentalnom dijelu izrađeni su uzorci u obliku kalota, te je provedeno balističko testiranje. Opisani su dobiveni rezultati i povezanost otpornosti na prodiranje s obzirom na broj slojeva UHMWPE vlakna.

Abstract (english)

In this Bachelor thesis, composite spherical caps were manufactured and analyzed. They were ballistically tested to imitate military helmets.
Theoretical part covers introduction of composites, their classification, properties and applications. UHMWPE fibers were closely described for their specific characteristics and wide spectrum of usage. Methods of manufacturing polymer composites were pointed out and their properties benefiting ballistic protection equipment.
In the experimental part samples in the shape of spherical caps were manufactured and tested to withstand ballistic penetrators. Based on testing, results were described and number of UHMWPE layers were correlated to impact resistance.
