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...

The aim of this study is to investigate effects of isothermal aging on mechanical properties of fiber metal laminates (FMLs) and glass/epoxy composites. For this purpose, both materials were fabricated using the wet lay-up manufacturing technique under vacuum pressure. Both the glass/epoxy composites and the FML specimens were then subjected to isothermal aging (130°C, dried air) for up to 5 we...

In the forming process of fiber-reinforced metal laminates (FMLs) product, exploratory compound technology, including hot stamping aluminum alloy and laying fiber prepreg which is named HFQ-FMLs was proposed to solve puzzles such as weak rigidity, low strength integration deformation with large difficulty, feasibility mechanical properties innovative were studied. Firstly, based on modified vol...

The transportation industry needs lightweight structures to meet economic and environmental demands. Composite sandwich offer high stiffness low mass, making them ideal for weight reduction in high-speed trains. objective of this research is develop a method cost optimization floors studied floor structure consists Fiber Metal Laminates (FML) face sheets honeycomb core.

This study aims to investigate the effects of elastomers on fiber metal laminates (FMLs) subjected low-velocity impact loads. A compounded natural rubber layer was added conventional FMLs containing glass/epoxy composite plies and Al 6061-T6 layers, measuring its effect behavior structure in indentation at energy levels 25 45 J. It found that addition an elastomeric back face increased structur...

Repairing of the cracks by fiber metal laminates (FMLs) was first done by some aeronautical laboratories in early 1970s. In this study, experimental investigations were done on the effect of repairing the center-cracked aluminum plates using the FML patches. The repairing processes were conducted to characterize the response of the repaired structures to tensile tests. The composite patches wer...

Hybrid composites become popular and are today used in a large number of contemporary structural applications. When compared to non-hybrid composites, hybridization offers additional benefits since the mixing cheaper, low-quality fibers, with more expensive fibers higher quality can improve properties composite without significantly affecting cost. Among improvements resulted from is fatigue be...

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...
