“…For the mechanical tests, the composites were cut as follows: for tensile test 120 x 20 x 3.5 ± 0.2 mm[34], compression test 12.75 x 12.75 x 3.5 ± 0.2 mm[35], flexural test 67 x 20 x 3.5 ± 0.2 mm [36] based on the Eqn. 1, and for impact test 100 x 100 x 3.5 ± 0.2 mm, where L is the length and d is the thickness of the composite.The fire behavioural test begins with burner calibration according to the ISO2685 standard[33] where 7 thermocouples were used to calibrate the flame temperature and SBG01 calibrate the heat flux at a distance of 3-inches from burner face. The ISO2685 standard states the standard flame temperature of 1100 ± 80 C and a heat flux of 116 ± 10 kW/m 2 , whereas the supply gas, primary and secondary air should be maintained at45 mm H 2 O, 435 mm H 2 O and 300 mm H 2 O respectively.…”

Two different properties of fibre-metal laminate composites (FML), including the fire behaviour and mechanical properties, were experimentally studied in this paper. The fibre-metal laminate composites studied were made of aluminium alloy 2024-T3, carbon fibre, flax, kenaf and epoxy resin/hardener arranged in different forms. The aims of the study are to assess the fire behaviour of the composites using ISO2685 standard and mechanical properties of the composite after withstanding the burn-through according to the standard. The fire test was carried out using ISO2685 standard using a propane-air burner, whereby the propane gas and air serves as the fluid to the system. The universal testing machine of the 100 kN load cell and gun tunnel were used for the mechanical properties test according to each test standard. The fire results showed that three of the FML composites considered in the study are fireproof composites while carbon fibre kenaf reinforced aluminium laminate (CARALL4) is a fire resistant composite. Carbon fibre reinforced aluminium laminate with aluminium alloy at the front and the rear face (CARALL2) withstood higher flame temperature than the other FML composites with 14.4%, 49.0% and 82.8% greater than CARALL1, CARALL3 and CARALL4 in terms of thermal conductivity. In terms of mechanical properties, it was also CARALL2 that has higher tensile, compressive, flexural and impact strength. Therefore, the study showed that carbon fibre flax reinforced aluminium laminate (CARALL3) which is the hybrid composite with green fibre can compete with fibre-metal laminate composites of pure synthetic fibre in terms of their properties.

Fibre-metal laminates (FMLs) offer advanced improvements over current available structural materials due to the excellent mechanical properties. In this work, the dynamic behaviour of the carbon fibre/epoxy, glass fibre/epoxy, aluminium 2024-T0, and fibre metal laminates were carried out. Furthermore, the different type of reinforced composites in FMLs and the effect of the layer sequence of metal layers were investigated. The composite laminates have been manufactured by a hot press machine. The free vibration tests were conducted to determine the dynamic characteristics of the samples. The accuracy of the experimental results was verified by comparing the numerical analysis results. The results indicate that the effect of thickness and the layer sequences of metal layers have a significant effect on the natural frequency of the FMLs.

“…FLMs are a kind of hybrid material consisting in metal sheets alternating to composite material laminates. The exceptional structural properties are due to the peculiarities of the materials the FMLs are made of; in fact, the FMLs constructed by aluminium and glass‐fibre composite that are the most used one for aeronautical applications are less strong than those based on carbon‐fibre reinforced polymer (CFRP): carbon fibre–reinforced aluminium laminates (CARALL) are about 10% stronger than glass fibre–reinforced aluminium laminates (GLARE) for tensile loads . In general, carbon‐based FMLs have superior characteristics, such as concerns energy‐absorption capacity, yield strength, tensile modulus, and fatigue strength, in comparison with aramid or glass fibre–based FMLs .…”

Fibre‐metal laminate (FML) is a material constituted by composite laminae and metal sheets, whose mechanical properties can be tailored by varying the thickness and the number of layers. For this reason, in the present work different types of FML made of carbon‐fibre–reinforced polymer and aluminium sheets were produced and tested; in particular, the influence of both the layer thickness and the layer adhesion was analysed through three‐point bending tests. It was found that both the abovementioned factors influenced the flexural strength of FML; precisely, the presence of an adhesive layer between the composite plies and the metal sheet made the flexural strength decrease, while this mechanical parameter increased passing from two metal sheets to only one.
