DEFORMATION CHARACTERISTICS OF CHOPPED FIBRE COMPOSITES SUBJECTED TO QUASI-STATIC TENSILE LOADING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This work presents deformation behaviour of cost effective chopped fiber composites. Use of chopped fibre is advantageous for manufacturing however complex shape parts production technology could be challenging. Batches ... -
IDENTIFICATION OF DAMAGED ZONES IN C/PPS SPECIMENS SUBJECTED TO FATIGUE LOADING BASED ON HIGH-RESOLUTION THERMOGRAPHY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)In this study high resolution thermography is used for identification of damaged zones in Carbon fiber/polyphenylene sulfide (C/PPS) long fiber composite specimens with induced impact damage subjected to tensile fatigue ... -
PRELIMINARY ASSESSMENT OF THE CHANGE IN THE MECHANICAL BEHAVIOR OF SYNTHETIC YARNS SUBMITTED TO CONSECUTIVE STIFFNESS TESTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Anchoring systems of offshore platforms are designed to work uninterruptedly for 20 to 30 years, and despite the increasing number of studies concerning these systems’ mechanical behavior in working conditions, most of ... -
SURFACE TREATMENT AND EXAMINATION OF GRADE 2 AND GRADE 5 TITANIUM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Surface characteristics play an important role in the implant-bone integration that is required for the long-term reliability of dental and orthopedic implants. In this paper, we investigate the effect of acid etching on ... -
DETERMINATION OF THERMAL RESPONSE OF CARRARA AND SNEZNIKOVSKY MARBLE USED AS A BUILDING MATERIALS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Physical weathering of marble, widely used as a cladding material on buildings, is one of the most common damaging mechanism caused by anisotropic thermal expansion of calcite grains. The extent of marble deterioration ... -

The aim of the project ... -
THE EFFECT OF SUPPORT PLATE ON DRILLING-INDUCED DELAMINATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Delamination is considered as a major problem in drilling of composite materials, which degrades the mechanical properties of these materials. The thrust force exerted by the drill is considered as the major cause of ... -
STRUCTURAL AND MECHANICAL CHARACTERIZATION OF DEFORMED POLYMER USING CONFOCAL RAMAN MICROSCOPY AND DSC
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Polymers have various interesting properties, which depend largely on their inner structure. One way to influence the macroscopic behaviour is the deformation of the polymer chains, which effects the change in microstructure. ... -
