“…GLAREs also showed high impact resistance, fatigue strength, superior corrosion, and fire resistance. [15][16][17][18] A unique possibility to enhance the overall characteristics of a sandwich material is accomplished through blending nanofillers in polymer while preparing the FRP plies. The blends of nanofillers enhances the specific physical properties of polymer.…”

This research work is focused on development of epoxy based fiber metal laminate (FML) that comprised of multi-walled carbon nano-tube (MWCNT), glass fiber, and aluminum metal sheet. The hand layup technique was employed to fabricate the sandwich FML with different weight percentages (3, 4, and 5 wt%.) of MWCNT. The mechanical properties of the developed FMLs were determined through tensile, flexural, lap shear, and hardness tests following ASTM and IS standards. The scanning electron microscope (SEM) was used to characterize the failure mechanism of composites. The FML with MWCNT offered superior tensile and shear properties up to the addition of 4 wt%. The MWCNTs were found to be agglomerated in the epoxy when added more than 4 wt%. The FML's showed larger deformation before complete failure in shear mode with respect to the addition of MWCNTs. However, there was no considerable improvement recorded in the flexural and impact behavior of the FML composition. The addition of MWCNT fillers in the epoxy turned it more brittle and exhibited comparatively less deformation before failure in flexural mode.

“…Currently, this test method continues to be used with the aim of further developing its potential applications [18,19,20,21,22,23,24]. However, the fact that most of the failures of materials destined for industrial use are due to fatigue phenomena means that it is necessary to carry out a study of the delamination process under dynamic loading [25,26,27,28], as some authors have proposed for different types of tests.…”

Influence of the Test Method on the Characterization of the Fatigue Delamination Behavior of a Composite Material under Mixed Mode I/II Fracture

et al. 2019

Composite materials manufactured by overlapping plies with certain specific geometries are likely to lose part of their strength due to the presence of internally delaminated regions. The aim of this paper is to experimentally evaluate the generation and propagation of these interlaminar cracks in a carbon-epoxy composite material subjected to fatigue loading under mixed mode I/II fracture. Two different test methods were used for this purpose: The standardized mixed-mode bending (MMB) test and the asymmetric double cantilever beam (ADCB) test, with the goal of exploring the viability of the ADCB test as a simpler alternative to perform than the MMB test, especially in fatigue testing. With this aim in mind and after prior static characterization of the material in which the critical values of the energy release rate were determined under both test methods, the levels of the energy release rate to be applied in fatigue tests were defined for two mode mixity ratios, GII/Gc = 0.2 and 0.4 (0.34 ADCB), and a fatigue loading ratio, R = Gmin/Gmax = 0.1. The G-N fatigue onset curves were subsequently obtained from these experimental data. The most relevant result of the study is that the fatigue limits obtained using the MMB method are generally more conservative than those obtained via the ADCB method.

This paper aims to reveal the deformation mechanism of glass fiber reinforced composites (GFRP)/aluminum-lithium (Al-Li) laminates under thermal shock or fatigue and verify reliability of shot peen forming for the composites. In this study, residual stresses in laminate after shot peening was analyzed using finite element model, and the simulation results were verified by experiments. It was found that the shot peened laminates, compared with pure metal panel, similarly exhibited compressive stress at the two external metal surfaces and tensile stress in GFRP layer. The residual stresses changed discontinuously at the metal/fiber and 0 /90 fiber interface owing to the different modulus. Moreover, stresses generated during curing process significantly affected the final deformation after shot peening. Residual stresses altered in each layer with the increase of temperature from 0 to 100 C, which caused the arc height of the laminate decreased. However, the arc height increased to initial dimensions when the temperature dropped to 0 C. Thermal shock process was proved that it hardly influenced the sample geometry. The stress relaxation behaviors were found in long-term thermal fatigue. 1100 cycles from À55 to 100 C, which lasted 4 h in every cycle, resulted in 5% decrease of the arc height. The deformation problem should be further concentrated on for components made of GFRP/Al-Li laminates and processed by shot peen forming technology.
