Title of the thesis:Research of influence of injection moulding process parameters on properties of short fibre reinforced thermoplastic parts
Summary:The aim of this thesis is research of influence of injection moulding process parameters on properties of short fibre reinforced thermoplastic parts. The injection process of thermoplastic is depended of many parameters, such as a geometry of the gating system, time, temperature, injection pressure, packing, etc. By changing the process parameters in the combinations with one of given types of gating system geometry, we can get a lot of differing orientations of fibres, which lead to different mechanical properties. Numerical analysis provide some results, but they are working on the simplify principle. Therefore, they offer only approximate results. Experimental detection of the orientation and the mechanical properties of short fibre reinforced thermoplastic parts will be time-consuming, but it is more accurate method. Using a comparison of both methods, it is possible to examine the orientation of fibres and to determine the impact of several parameters. This orientation can be reflected also by changing properties such as mechanical properties.
Key words:Injection moulding, Fibre orientation distribution, Mechanical properties, Numerical simulation
