Analysis of composite structural elements

Purpose: The themes of the study are composite structural components. For this purpose have been designed and built several research positions. Design/methodology/approach: Using different structural materials to build new device components requires multiple tests of the components. Research posts were designed in the advanced graphical program CAx Siemens NX 7.5. Analysed samples were made from the glass fibre, aramid and carbon of various weights. Due to the specific use of composite materials it focuses on the elements in the form of plates and flat bars. For the examination of experimental strain gauge technique was used bead, the force sensor and displacement sensor. The experimental methods were compared with computer simulation using the FEM. Findings: The aim of this study was to determine the basic material constants and a comparison of the experimental method and the method of computer simulation. Research limitations/implications: Change the number of layers and how to connect the laminate with the steel plate changes mechanical properties of the structural component. Practical implications: The ultimate result will be knowledge on the different forms of laminates, such as material properties, the stresses in all layers, strain and comparing the results obtained by two methods. Originality/value: The expected outcome of the study will be the composition and method of joining composite laminate with a steel plate to the possible application in the repair and construction of structural elements of freight wagons.
