fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

Despite graphene's long list of exceptional electronic properties and many theoretical predictions regarding the possibility of superconductivity in graphene, its direct and unambiguous experimental observation has not been achieved. We searched for superconductivity in weakly interacting, metal decorated graphene crystals assembled into so-called graphene laminates, consisting of well separate...

Abstract Compared with the resin‐based composite laminates, fiber metal laminates (FMLs) have superior impact resistance. In this study, investigations were made to reveal effects of stacking sequence on low‐velocity failure mechanisms and energy dissipation characteristics carbon reinforced plastics (CFRP)/Al hybrid same areal density. Experiments carried out characterize typical mechanical re...

Guided wave detection using different fiber optic sensors and their applications in damage detection for composite laminates were systematically investigated and compared in this paper. Two types of fiber optic sensors, namely fiber Bragg gratings (FBG) and Doppler effect-based fiber optic (FOD) sensors, were addressed and guided wave detection systems were constructed for both types. Guided wa...

Machined surface quality determines the reliability, wear resistance and service life of carbon fiber reinforced plastic (CFRP) workpieces. In this work, the formation mechanism of the surface topography and the machining defects of CFRPs are proposed, and the influence of milling parameters and fiber cutting angles on the surface quality of CFRPs is obtained, which can provide a reference for ...

In this research, the influence of carbon nanotubes agglomeration on buckling behavior multi-phase CNTs/fiber/polymer/metal composite laminates cylindrical shells under hydrostatic pressure was investigated. Governing equations were derived according to Kirchhoff-Love’s first approximation shell theory and solved by a combination Galerkin Fourier series expansion methods. Equivalent elastic pro...

Abstract During deep drawing processes of fiber metal laminates, such as the newly developed in-situ hybridization process, fibers and sheets come into contact while dry fabric is infiltrated by a reactive matrix system. The viscosity increases polymerization starts during deep-drawing. In laminate drawn thermoplastic system injected glass layer in resin transfer molding process. forming lamina...

A novel, two-scale computational model has been developed to predict the progressive damage and failure responses of fiber-reinforced composite laminates using the material properties at the constituent (fiber and matrix) level. These properties were measured from coupon level tests on a unidirectional lamina of the same material system. In the proposed computational scheme, the macroscale fini...
