“…The obtained p-value (0.001) reveals that the considered conditions significantly affected the impact strength and Tukey's test shows that the superior impact strength is attributed to CoRAL P3. For FML sandwiches, crack propagation in the skin-core interface and through the core was responsible for the material failure [1]. In the epoxy and polyester CoRALs, fibre fracture and both aluminium and matrix fractures were observed (see Figure 7).…”

“…The energy released with crack initiation or fracturing needs to be dissipated via various mechanisms. Fibre bridging and pull-out is one of the dominant methods of post-impact energy dissipation [1].…”

“…As a result, the new structures have advantages over conventional fibre-reinforced composites, e.g. sustainability, resistance to fatigue, corrosion and impact [1]. ARALL, GLARE and CARAAL are traditional FMLs with synthetic fibrebased cores (carbon, glass and aramid fibres) [2].…”

“…ARALL, GLARE and CARAAL are traditional FMLs with synthetic fibrebased cores (carbon, glass and aramid fibres) [2]. However, alternative cores based on natural fibre-reinforced composites [3] [4][5] [6] 2 manufactured with metallic faces composed of magnesium [1], titanium [7] , and a variety of aluminum alloys such as 2024-T3 [6] [8], 7075-O [9], 6061-O and T3 [9] and aluminumlithium [10]. The mechanical properties and thence the final applications of the FML depend on the selected metallic face and core.…”

Fibre Metal Laminates (FMLs) are composite structures that comprise alternating metal layers and fibre-reinforced polymer composites (FRCs) combining their distinct physical-mechanical properties. Traditional FMLs are based on synthetic (carbon, glass and aramid) fibres. However, alternative FMLs based on natural fibre-reinforced composites have been developed to take advantage of available natural resources. A new ecofriendly FML sandwich based on random coir fibre-reinforced epoxy and polyester resin was developed in this research. Mechanical tests revealed that the tensile properties were fully dominated by the aluminium sheets, which were treated with alkali for degreasing and wash primer in order to enhance interfacial bonding. Such treatment efficiently reduced delamination and increased the flexural modulus (~67%). A similar increase in flexural (~22.94%) and impact strength (~99.16%) as well as in skin stress (~20.89%) of the new FMLs proposed was observed owing to the flexural and impact strength of composite cores and better core-layer stress transfer upon the aluminium treatment.

“…Hence, it was suggested that rubbers could be incorporated with Polymers like MMCs and FRPs. According to Das et al [12], Elastomer based fiber-metal Composites did not have a considerable amount of increase in toughness, but it was able to absorb a significantly high amount of Impact Energy. Therefore, there arose a need to study the mechanical properties of GFRP with a complete layer of rubber.…”

In this paper, the mechanical behavior of GFRP laminates reinforced with Elastomers under Impact and Tensile loading conditions has been studied. The GFRP laminates have bidirectional orientation so that it can take loads acting along both x & y-axis. Composite made of E-glass fibre and Araldite LY 556 resin was reinforced with Silicone Rubber elastomer. The GFRP laminates were manufactured utilizing the Compression Molding (Sheet Molding) Process. Elastomers are believed to improve the Impact and Tensile Strength of GFRP laminates. Which can be studied only by comparing the Impact and Tensile test results of GFRP with Elastomers to those without Elastomers. A total of ten specimens, five GFRP laminates without Elastomers, and five GFRP laminates with Elastomers were manufactured. For each type, two samples were used to obtain Tensile Strength at 34oC & 50oC, and then three specimens were used to gain Impact Strength. The Tensile Strengths were obtained from the Tensile Test as per the ASTM D638 standard of testing, and the Impact Strengths were obtained from the Charpy Impact Test as per the ASTM D256 standard of testing. The specimen dimension for Tensile Test was 4.97 mm * 12.9 mm, and the specimen dimension for the Charpy Impact Test was 63.7 mm * 12.7 mm. The values for Impact Strength and Tensile Strength for each type of specimen were tabulated, utilizing which graphs were plotted between Stress vs. Strain. These values were used to analyze the Mechanical Properties of GFRP with Elastomers under Impact and Tensile Behavior.
