Abstract: The wear behavior of CFRP laminates with nano-particles dispersed surfaces of Al2O3 or carbon has been investigated and compared with that of conventional CFRP which is without particles dispersed surfaces. As a result of comparison, it is shown that the CFRP laminate with Al2O3 nano-particles dispersed surfaces inherently had low coefficient of friction and high sliding wear resistance. The measured value of specific wear rate was 3.5x10-7mm3/Nm, independently of sliding time. The wear behavior of CFRP laminates with carbon nano-particles dispersed surfaces has been more effectively improved. The measured specific wear rate of this material was in the range of 10- 7mm3/Nm in spite of comparatively small amount of nano-particles dispersion, which is relatively good as tribomaterial. For the successful application of this method, it is essential to explore the optimum amount of Al2O3 or carbon nano-particles to be dispersed onto prepreg surfaces. The deflocculation of the agglomerated particles and their homogeneous dispersion and good impregnation are the key points in this technology.

Abstract: Analysis of contemporary cyclone gas purification apparatus was carried out in this article Calculation of the characteristics of the counterflow cyclone in application of pressurization system of the LV fuel tanks with gas pressure accumulator has been executed. 3D-model of the counter-flow cyclone was built. Numerical modeling of soot-cleaning process in countercurrent cyclone has been performed using ANSYS Fluent.

Abstract: The object of our project is a design and verification of composite elements of defined shape with effective content of carbon particles and fibers. These composites should be able to monitor internal state of selected structural elements in order to eliminate negative effects of loading.
