Development and application of computational model of ballistic resistant composite laminate
Urbášek, Jan ; Kubík, Petr (referee) ; Petruška, Jindřich (advisor)
This master thesis is aimed at computational modeling of ballistic resistant layered laminate. The introductory sections of the thesis are aimed at understanding the individual topics that are closely related to the interaction of the projectile and target and computational modeling of this process. The main goal of this thesis was to create a computational model that is able to reflect the behavior of aramid fabric during the interaction with the projectile. During the development of the computational model were used more methods of modeling and also more material models were used. For the purposes of the development of the computational model were used the available data of the companies SVS FEM s.r.o. and VVÚ s.p. The outcome of the diploma thesis is a computational model of aramid fabric which is designed for ballistic protection simulations. This model is validated on the basis of available experiments. The validated computational model is then applied to the simulation of ballistic protection.

Biocompatibility optimization of fabric composites by calcium phosphates
Sochor, M. ; Balík, Karel ; Suchý, Tomáš ; Sucharda, Zbyněk
Composite materials based on a polyamide fabric and a polydimethylsiloxane matrix were designed for application in bone surgery. In order to increase the bioactivity, 2, 5, 10, 15, 20 and 25 vol. % of nano/micro hydroxyapatite and tricalcium phosphate were added. The effect of the additives on the mechanical properties was studied. Simultaneously, changes in the inner structure of the composites were investigated by means of image analysis.
