Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

Abstract   Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...

Fiber metal laminates (FMLs) have been successfully manufactured by the vacuum assisted resin transfer molding (VARTM) process developed at NASA Langley Research Center. A flow visualization fixture of the FML, VARTM process was constructed and used to observe the resin infiltration process. Results of the flow visualization experiments are reported and compared with the predictions of a VARTM ...

Mechanical properties of the fibers extracted from the areca are determined and compared with the other known natural fiber coir. Further these Areca fibers were chemically treated and the effect of this treatment on fiber strength is studied. Areca fiber composite laminates were prepared with randomly distributed fibers in Maize stalk fine fiber and Phenol Formaldehyde. Composite laminates wer...

This paper portrays the various combinations of nanomaterials and matrix materials which were used to fabricate the nanocomposite laminates with and without fiber. An in-depth analysis was made on the various ways of preparing the nano influenced matrix and composite panels. In addition to this, an effort has been made to afford an outline of the impact of nanofillers within the matrix from the...

In this article, the effect of hygrothermal aging on mechanical properties of fiber metal laminates (FMLs) and E-glass/epoxy (GE) composites is investigated. First, FML and GE specimens were built using wet lay-up technique under vacuum pressure. Hygrothermal aging simulation was then carried out on both specimen types in distilled water at a constant temperature of 90 °C for 5 weeks. The resul...

A stable method of calculation of the electromagnetic response of planar anisotropic laminates to an active source with limited distribution along the strata direction is developed. The laminates can be sandwiched between isotropic, anisotropic, or perfectly conducting covers/substrates. The source is either inside the laminates or in the cover or substrate. Based on the propagator matrix metho...

In this study, experimental investigations are implemented to evaluate the effect of incorporation graphene nanoplatelets (GNPs) on low-velocity impact behavior composites and fiber metal laminates (FMLs). The hand layup technique is employed fabricate composite specimens FML panels with 2/1 configuration. Impact response damage patterns unmodified modified subjected various energy levels compa...

The objective of this research was to evaluate the effect of kenaf fiber orientation and furnish formulation on the properties of laminated natural fiber–polymer composites (LNPC). The uniaxial fiber orientation provided property enhancement of the LNPC. The randomly oriented kenaf fibers, regardless of fiber contents in the laminates, provided an equal performance compared to the composites ma...
