“…There are several studies about the mechanical properties of FMLs, paying attention to the composite type [15], the thickness of the layers [16], the metal's surface preparation [17], and the fibre orientation [18]; however, there has not been much research performed on the hygrothermal effects on carbon-based FMLs, and it is still unclear how long layers will stay bonded, particularly in seawater environments or at high temperatures. Yu et al [14] prepared titanium/Carbon-Fibre-Reinforced Polymer (CFRP) FMLs by anodising the titanium sheets and grafting the CFRP layers with multi-walled carbon nanotubes.…”

Fibre Metal Laminates (FMLs) are very interesting materials due to their light weight coupled with their high stiffness, high fatigue resistance, and high damage tolerance. However, the presence of the polymeric matrix in the composite layers and of polymeric adhesive at the metal/composite interface can constitute an Achille’s heel for this class of materials, especially when exposed to a hot environment or water. Therefore, in the present article, aluminium/carbon fibre FML specimens were produced, aged by considering different hydrothermal conditions, and then, subjected to mechanical testing. The End-Notched Flexure (ENF) test was considered for this activity. It was found that the first ageing stage, consisting of submersion in saltwater, was very detrimental to the specimens, while the second stage, composed of high and low temperature cycles, showed an increase in the maximum load, probably due to a post-curing effect of the resin during the higher temperatures of the ageing cycles and to the dissolution of salt crystals during the subsequently ageing stages in distilled water.

“…The pressure was applied by placing a moderated load on it and cured at room temperature for 24 hours. the result of 1 mm/min in the plain weave CFRP has lower loading than unidirectional fiber [2]. To produce metalliccoated carbon fiber-based composites, a new innovative technique that combines Cold Spray and lay-up molding of composites are envisioned.…”

 Fibers, metal and resin were made up together using mold and compression method.  Hand layup was used and Taguchi method for obtaining the optimum parameter.  The workpiece with most significant parameters is FG-Al with polyester resin.  The best Ra after milling is for FG-Al, CF-Al with polyester resin.Recently, composite materials were widely used in different applications due to their lightweight, and good thermal and mechanical properties. In this study, an attempt to manufacture laminate composites by hand layup was performed. Also, optimal parameters for the best surface roughness were investigated. Therefore, three parameters had been examined; spindle speed, feed rate, and depth of cut. The L9 Taguchi orthogonal array, signal to noise (S/N) ratio, and analysis of variance (ANOVA) were selected to determine the optimum parameters. To create composites, the compression method was employed. Four different types of composites were manufactured with 2.8 mm thickness, to determine the effect of the parameters on the surface roughness and for specified parameters using the CNC milling machine. The weight fraction ratio of fibers was 39%, the polymer was 34%, and 27% for Aluminum. The results showed that the optimum parameters for surface roughness in milling machine of composites for Polyester resin for aluminum-fiberglass composite are; spindle speed=5000 r.p.m, feed rate=1600 mm/min, depth of cut=1.6 mm and Ra=1.853 μm, and for epoxy resin; aluminum-carbon fiber composite is spindle speed=4000 r.p.m, feed rate=800 mm/min, depth of cut=1.2 mm and Ra=2.43 μm.

This paper investigated the failure behaviour of medium thick carbon fibre reinforced aluminium laminates (CARALL) panels under transverse local quasi-static contact crush experimentally and numerically. Four types of CARALL specimens with a 3/2 configuration were manufactured by hot-pressing process using two type of aluminium alloys (2024-T3, 7075-T6 aluminium alloy) and CFRPs with different lay-up ([0°/90°/0°]3, [45°/0°/-45°]3). Three dimensional Hashin progressive failure model in quadratic strain form with damage evolution laws defined by subroutine VUMAT based on ABAQUS was used to simulate the composite layers. The bilinear cohesive contact model was used to predict interfacial failure. Aluminium alloys were defined by Johnson-Cook model. Numerical predictions composing of load-deflection curves and failure mode were matched closely with experimental results. The results of the analysis shown that delamination in CFRP/Al interfaces was the initial damage of the tested CARALL panels. Matrix failure occurred after the delamination closely. The maximum load bearing was determined by fracture of aluminium alloy. Fibre breakage was responsible for complete failure of specimens.
