This study concerns with the optimisation of a fibre-reinforced composite material ply book and application to an aeronautical component. The presented solution is recyclable FML (Fibre Metal Laminate). Recyclable structural PMCs (Polymeric Matrix Composites) developed up-to now in ENEA had be improved satisfy high-demanding fire characteristics requirements aeronautics, particularly for case c...

the objective of this experimental work was to assess the drop impact damage onwoven glass fibre reinforced polymer composite laminate through online method and offlinemethod. online monitoring of drop impact damage was carried out by acoustic emission (ae)technique and ae signals during the drop impact test were captured. from the analysis of aesignals, it was observed that as the impact energ...

fiber metal laminates are hybrid laminates consisting of thin alternating bonded layers of aluminum and fiber/epoxy. arall (aramid aluminum laminate) and galare (glass fiber reinforced aluminum laminate) are specific kinds of fiber metal laminates that consist of thin aluminum sheets along with kevlar/epoxy and glass/epoxy composite layers, respectively. in this study, nonlinear tensile behavio...

The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. To enable the manufacture and assembly of composite structural parts, reliable and cost-effective joining technologies must be developed. This thesis addresses several aspects of joining and load introduction in carbon-fibre reinfor...

In this research, effect of opening on the buckling of FMLs (Fiber Metal Laminate) is studied. Samples are made of a laminate, epoxy resin reinforced with four layers of woven basalt fibers, inserted between two Al plates. Different samples are prepared, tested and studied; one group without opening and the other two groups with circular openings of radii 10 and 20 mm. In all samples buckling i...

This paper aims to experimentally and numerically probe fatigue behaviours lifetimes of novel GLARE (glass laminate aluminium reinforced epoxy) laminates under random loading spectrum. A mixed algorithm based on damage concepts three-phase materials was proposed for modelling progressive mechanisms life fibre metal (FML) To validate the algorithm, tests were conducted 2/1 3/2 subjected spectrum...

Hybrid fibre reinforced polymer (FRP)-timber (HFT) thin-walled structural members made out of thin-timber veneer and composite laminates are a sustainable alternative to light-weight steel aluminium members. Preliminary studies on HFT structures have demonstrated the potential be used as high performing This study is aimed at investigating effect manufacturing pressure type mechanical propertie...

In this paper, a method to obtain correction factors for in-plane shear properties in fibre-reinforced polymers with high Poisson’s ratio under biaxial load conditions and at loads is presented. Experimental testing shows the deviations from classical laminate theory such cases. The transverse deformation general form of and, ±45° angle-ply laminate, increases strain. This effect shown exist lo...

This work studied the mix mode-I/II fracture behaviour of an aerospace-grade carbon fibre/epoxy composite that was interlayer-toughened by Polyamide-12 (PA), Polyphenylene-sulphide (PPS), Polyimide (PI), Polyethersulfone (PES) and Polyethylenimine (PEI) fibres. During laminate curing process, PA fibres melted, PPS PI kept in their original form PES PEI dissolved epoxy matrix. resulted different...
