“…called fibre metal laminate (FML) composite. FML composite combines the properties of the materials used to produce a highquality component that can be used in aerospace and automobile industries [2][3][4][5][6][7][8][9]. FML composite has been used in aerospace industry for over seven decades, where the FML was used in F-27 for the bonding in Fokker aircraft due to its lightweight and damage tolerance properties [10].…”

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.

“…What this experience has brought to light is that in order to fully benefit from the composite nature, aspects must be resolved that require metallic‐like properties such as ductility. Hence, various studies conclude that hybrid material solutions can further increase the structural performance, followed by research where composites are hybridized with the addition of metallic constituents . Because the laminar structure of composites with metallic inserts resembles the typical lay‐up configuration of Fiber Metal Laminates (FMLs), the first step in hybridization of composites requires learning from this hybrid FML technology.…”

To further optimize aeronautical structures, an increased level of material hybridization is required. Optimization efforts aim to identify optimal design solutions that satisfy prescribed requirements. However, this demands reversal of currently available knowledge on hybrid structural technologies, which are often formulated as theories predicting performance based on known load cases and selected material configurations. After briefly reviewing the available fundamental theories for strength, fatigue, and damage tolerance of hybrid structures, this paper discusses the challenges in reversing these theories. Solutions are proposed in which theories can be approximated to significantly reduce the computational time while maintaining the required level of accuracy.

“…Constituents of GLARE are adhered together using epoxy FM-94 that shows properties that change with time and temperature. Although, the understanding and applications of FMLs are further developed by researchers [1][2][3][4][5], the effects of the curing process of epoxy FM-94 on residual stresses and the final geometry are not studied in detail yet. The cure process results not only in deviations from designed dimensions which hamper the assembly but also in residual stresses by which the load capacity, fatigue strength, damage tolerance and residual strength of the material decreases.…”
