“…Further numerical simulations are necessary to help establish injection-moulded NFCs in the automotive industry. First, successful research steps were taken to perform injection-moulding simulations with NFCs [12][13][14][15][16][17]. To include the fibre breakage behaviour of natural fibres in commercial injection moulding simulations further research is necessary.…”

Abstract:To establish injection-moulded, natural fibre-reinforced polymers in the automotive industry, numerical simulations are important. To include the breakage behaviour of natural fibres in simulations, a profound understanding is necessary. In this study, the length and width reduction of flax and sisal fibre bundles were analysed experimentally during compounding and injection moulding. Further an optical analysis of the fibre breakage behaviour was performed via scanning electron microscopy and during fibre tensile testing with an ultra-high-speed camera. The fibre breakage of flax and sisal during injection moulding was modelled using a micromechanical model. The experimental and simulative results consistently show that during injection moulding the fibre length is not reduced further; the fibre length was already significantly reduced during compounding. For the mechanical properties of a fibre-reinforced composite it is important to overachieve the critical fibre length in the injection moulded component. The micromechanical model could be used to predict the necessary fibre length in the granules.

“…Injection molding of polymer-filled materials is very challenging due to the noticeable different flow behavior regarding neat polymers. Wan Abdul Rahman et al [12] suggested that the lack of knowledge about the material characteristics in polymer composites is responsible for incomplete part fillings and other defects. Furthermore, today it is common to use simulation tools before processing the plastic part in order to optimize the processing parameters such Andrzejewski et al [13] reported.…”

In this study, the influence of MgO addition on mechanical properties of the injection molded alumina was investigated. Firstly, alumina feedstocks (without adding MgO) were prepared to determine the optimum powder/binder ratio by the capillary rheometer. Then, MgO was added at 0.5, 1 and 1.5 wt.% to alumina feedstocks at the optimum ratio. Moldflow simulation analysis (MSA) was performed to obtain injection parameters (injection pressure, flow rate and feedstock temperature) before the real molding operation. Through the agency of the pre-operating parameters obtained from MSA, preliminary trials were carried out by molding machine for successful specimens (tensile and bending). By comparison of experimental and analytical results, the error rate of injection parameters was determined for both specimens. The maximum strengths of bending and tensile test values were found 158 MPa and 69 MPa (in specimens containing 1 wt.% MgO), respectively. Analysis of SEM revealed that specimens containing 1 wt.% MgO had less porosity.K e y w o r d s : alumina, powder injection molding, rheology, sintering, moldability
