Component Failures

Due to the increasing demands on automotive components, manufacturers are relying on injection moulding components from fibre-reinforced polymers in an attempt to increase strength to weight ratio. The use of reinforcing fibres in injection moulded components has led to component failures whereby the material strength is hampered through the formation of weldlines which are also a problem for unreinforced plastics. In this study, an industrial demonstrator component has the injection locations verified through a combination of fibre orientation tensor simulation and optical microscopy analysis of key locations on the component. Furthermore, the automotive component manufactured from 30% glass fibre–reinforced polyamide 6-6 is simulated and optimized through a Taguchi parametric study. A comparison is made between the component, as it is currently manufactured, and the optimum processing parameters determined by the study. It was found that the component can be manufactured with roughly 7.5% fewer weldlines and with a mould fill time 132 ms quicker than the current manufacturing process.

In this experimental study, the tensile behaviour of bolted joints of pultruded glass fibre reinforced polyester sandwich composites was investigated. The transverse specimens cut normal to the pultrusion direction failed by net-tension whereas the longitudinal specimens cut parallel to the pultrusion direction failed by a combination of bearing and shear-out modes. The joint strength was dependent on the specimen geometry in the case of transverse specimens whereas it was not in the case of longitudinal specimens.

The out-of-plane performances of brick masonry panels with different retrofitting patterns using glass fibre reinforced polymers (GFRP) have been studied under three-point loading test. The panels were retrofitted on one side and both sides with different geometric configurations. The retrofitted specimens increased the failure load from 19.6 kN (UR) to 79.2 kN. It was observed that the flexural strength of the retrofitted patterns increased from 31.58% to 150% when compared to un-retrofitted specimens. Also, the bending moment of the retrofitted panels increased from 5.94 kNm to 8.96 kNm when retrofitted with one side, while it goes up to 14.88 kNm when retrofitted with both side as compared to un-retrofitted specimens. Further, it also observed that the panel with cross retrofitting showed more efficiency in terms of flexural strength, bending moment, stiffness and deformation capacity.
