The use of natural fibre reinforced polymer composite in fibre metal laminate (FML) is the current interest. The potential and performance of FML based on natural fibre have been investigated. This paper investigated the effect of different stacking configurations (2/1, 3/2 & 4/3) subjected to quasi-static indentation test for oil palm empty fruit bunch fibre metal laminates (OPFML). This study used aluminium 6061 as a laminate skin and oil palm empty fruit bunch fibre reinforced polypropylene composites as a laminate layer. A motorised hydraulic moulding test press machine was used in this study to bond the FML panels at 155 °C, 1 kg/cm? and 4 min and for composites fabrication at 185°C, 35 kg/cm² and 8 min. Experiments were performed using a 12mm diameter hemispherical indenter with a constant strain rate of 1.0 mm/s. The indentation behaviour of OPFML panels were presented based on the peak load, maximum displacement, energy absorption and specific energy absorption (SEA) values. The results show that the highest stacking configuration, OPFML 4/3 has the highest value of the peak load, energy absorption and specific energy absorption due to the stiffer behaviour. From this study, it is found that the failure mode of quasi- static indentation test showed the damaged on aluminium and composite layers. Therefore, this study concludes that the stacking configuration influenced the indentation behaviour of OPFML panels. [ABSTRACT FROM AUTHOR] |
