Abstract

The subject of this thesis is to perform mechanical tests of rigid ballistic protection made of composite materials. The topic builds on already developed composite ballistic materials and complements the study of mechanical properties by assessing the changes in these properties after exposure to ultraviolet (UV) electromagnetic radiation. The work uses existing research on the Twaron® material and previously determined strength reduction values after 1-month exposure. Experimental samples of composite plates made of this material will be produced using selected manufacturing technologies based on previous analysis. Mechanical properties of the samples will be measured after 4-month exposure in a defined environment and the results will be compared. Practical tests will be performed to determine the influence of manufacturing technology and the environment on the measured mechanical properties.

Keywords: Mechanical testing, ballistic protection, Twaron, material degradation
