Measurement of elastic constants of orthotropic C-C composite plates by resonant frequency method
Černý, Martin ; Glogar, Petr
A method was developed for determination of elastic constants of textile composite materials based on measurement of resonant frequencies of longitudinal and transversal vibrations of Timoshenko's beam.
Young's modulus of heat-resistant fibrous composites at elevated temperatures
Černý, Martin ; Glogar, Petr ; Nekoksa, Pavel
Elastic behaviour of unidirectional composites with matrix derived from cured polysiloxanes and reinforced with SiC (Nicalon) or alumina (Nextel) fibres was measured at temperatures up to 1300řC in order to assess limits of their potential utilization as structural material in air environment.
Oxygen resistivity of 2-D composites based on E-glass and siloxane
Balík, Karel ; Černý, Martin ; Kolář, František ; Křena, J.
2-D composites prepared from glassy fabric and siloxane resin as a matrix were cured and subjected to pyrolysis at 400, 500, 600řC in nitrogen. Materials were oxidized in dried air at 400 and 700řC for a period of 1h.
Interlaminar shear strength of textile reinforced carbon-carbon composite
Kotek, Jiří ; Glogar, Petr ; Černý, Martin
Interlaminar fracture of carbon fabric reinforced carbon composites with different volume fractions of reinforcement (Vf = 36 - 60 %) was investigated by tensile loading of double-notched specimens. Dynamic tensile and in-plane shear moduli of all materials increased with increasing Vf. The interlaminar shear strength yielded maximum values for specimens with volume fraction Vf ~ 48 %. After graphitisation, the in-plane shear modulus fell remarkably which is probably due to "stress graphitisation" of the matrix.
Elastic and fracture properties of refractory ceramic matrix composites at 900-1300řC
Černý, Martin ; Glogar, Petr ; Dusza, J.
Young's modulus of refractory ceramic matrix composites with unidirectional reinforcement by Nextel 720 or Nicalon NL202 fibers was measured in air at 900-1300řC. Above 1200řC the modulus decreases remarkably and it depends also on the strain rate.

Balík, Karel ; Sochor, M. ; Sedláček, R. ; Suchý, Tomáš ; Černý, Martin ; Hulejová, H. ; Pešáková, V.
Mechanical properties and compatibility of composites based on glass and polysiloxane as a biomaterial.
Kompozity na bázi skleněných vláken - bioaplikace
Balík, Karel ; Sochor, M. ; Suchý, Tomáš ; Sedláček, R. ; Černý, Martin ; Hulejová, H. ; Pešáková, V.
Mechanical and biochemical properties of composites based on glass and polysiloxanes.
Kompozity na bázi bioskla
Balík, Karel ; Sochor, M. ; Suchý, Tomáš ; Černý, Martin ; Sedláček, R.
The development of a C/C composite in a form of intevertebral cages and comparision with composite based on glass and polysiloxane were described.
Electronic banking in the CR and its possibilities
Černý, Martin ; Matuštík, Ondřej (advisor) ; Richtrmocová, Klára (referee)
Bachelor thesis deals with the most commonly used forms of electronic banking, which offers banking institutions in the Czech Republic and abroad. In the theoretical part describes the development elektornického banking and the benefits that this product offers for banking institutions and their clients. The practical part is focused on the controversy with the views of columnist Nicholas G. Carr. His published articles are at work confronted with the views of IT professional community as discretionary author argues that the general benefits of the use of information systems for banks.
