VEGA project: | Usability development of modern build-in contact-less micro sensors for modern composite construction operational safety improvement |
Project summary: | Composite materials representing the main material group used in aviation. Compound of composite materials overcome 50% of aircraft construction materials for big airliners and reach 100% in a small sports aircraft. Scope of this project is to analyse possibility of using build-in contactless sensors based on magnetic microwires for state diagnostic of small aircraft composite construction. Project scope is continuing of successful project VEGA 1/0286/13, focused on contactless sensors of tensile stress in composite materials, linked to successful project APVV-0266-10 and EDA-ICET (European Defence Agency) SESAMO (Sensors for Structural Monitoring). Such sensors have similar dimensions and almost similar surface than composite materials fibres used in aircraft constructions, thus its embedding into construction do not create any structural defects. |

VEGA project: | Magnetometers Based on Magnetic Microwires |
Project summary: | Magnetic microwires are modern materials research of which is worldwide developed and by far not finished. They are composite materials, which consist of a metal core (with the dimension of 1 - 50 micrometres) and of a glass coated (with the thickness of 2 - 20 micrometres). One of the multiple potential possibilities is their utilization in the area of weak magnetic fields measurements in the role of primary power convertors. Miniature dimensions and ideal axial symmetry makes them suitable candidates for the sensing elements of RTD (Resident Time Difference) fluxgate magnetometers. However microwire characteristics are considerably dependent on their chemical composition and thermomagnetic treatment therefore intensive research for the optimality achievement in this application is necessary. With the continuously on-going research and development of sensors in addition to the apparent trend of miniaturization also the need of intelligent output signals processing is connected because that is the way how also from the low-cost and available sensors precise "smart sensors" can be made. Modern technological solutions of RTD magnetometers, design and verification of selected innovative measuring methods and calibration procedures are therefore a part of the project. |

VEGA project: | Contact-less microsensors of internal mechanical stresses in composite materials |
Project summary: | Carbon and glass composite materials - laminates are nowadays one of the basic construction materials. Their wide enhancement by pipes, pressure tanks, ship fuselages and airframes or missiles construction results into the need to sense internal mechanical stresses induced by strain, ageing or in-situ by their production. The goal of the project is to design and electronically realize miniature contact-less sensors - tensometers based on the amorphous or nanocrystalline magnetic microwires, which thanks to their dimensions can be embedded between the layers of composite materials. Magnetic microwires are form the dimensions, fibre structure and glass coat point of view almost identical with the own composite fibre, which results into the minimum probability of parasitic internal defects creation. |

VEGA project: | Tribologic aspects of sintered materials failures as a result of rolling contact fatigue and wear |
Project summary: | The subject of project is to study the behaviour of classical sintered ferritic materials with the density cca 7 g.cm-3 under contact fatigue and wear conditions. Sintered materials, by their specific structure (presence of pores), are known for their different responses to different forms of stresses. These facts along with the intensive expansion in production of spare parts on the basis of sintered materials, mostly in automotive industry, call for both basic research and systematic monitoring of attributes affecting service life of materials under stress. The results achieved will widen the area of knowledge in this field and assist in establishing the priorities of main directions of basic or applied research. |

VEGA project: | Microstructural Fracture Mechanics of High Strength Sintered Steels |
Project summary: | The objective of the proposed project is to gain a comprehensive understanding of the effect of microstructural parameters on crack initiation, subcritical crack growth and crack propagation in newly developed Cr-Mo-Mn sintered steels under tensile and fatigue loading. The following topics will be studied in particular:
The appropriate modification of chemical and microstructural compositions and/or processing conditions for improving both monotonic and fatigue properties of the tested steels will be investigated. It is expected that the results of the project will be used for reliable prediction of composition and processing of these Cr-Mo-Mn alloyed sintered steels to attain high resistance to subcritical and critical crack growth, and hence with improved both static and fatigue properties. |

Projekt KEGA: | Proposal of content and study methods modification in the electronics specialization with the intention of the study program Sensorics of the 1st and 2nd degree of university study of alternative education |
Project summary: | The disinterest in the university study of technical specializations including electronics has become the all-European problem. Furthermore bachelor graduates are only weakly prepared for the practice. The project wants to propose an alternative to a possible solution of insinuated problems by the change of the content and study methods change in the Electronics specialization, specifically in the study program Sensorics, by the proposal of integration of selected parts of study, by distinguished exploitation of computer simulations and multimedia, by the shift of the emphasis on the encompassment and user acquisition of SW tools such as Matlab – Simulink, Mathematica, Multisim, QuckField and so on for rigorous qualitative, physical and system understanding of the study issue also on the so called popular scientific base. |
