“…In addition, first modes of natural frequency values with loss and storage modulus of the samples are given in Table 4. Results from dynamic tests suggested that increasing of the natural frequency was explained by the fact that the elastic modulus enhancement of OP particles included test samples [24]. However, increase in the elastic modulus may not meant the enhancement of the damping properties since the damping property highly depends on viscoelastic nature of the materials, revealing the better vibrational energy absorption, exhibiting high modulus of storage [25].…”

The waste of olive pomace (OP) particle filler was incorporated with glass fiber-reinforced composites (GFRP)/epoxy resin to manufacture OP particles-modified GFRP composites. Different weight ratios (0.5, 1, 2, 5, 10, and 15 wt%) of OP particles were incorporated within the common matrix of epoxy resin to investigate the effects of OP particles on tensile, flexural, and vibration damping properties on GFRP composites. In the mechanical tests, addition of OP filler contributed the significantly enhancement in tensile and flexural modulus, and samples at 5 wt% of OP filler showed highest flexural and tensile strength, while further addition of OP filler resulted in reduction of maximum elongation value at breaking point. In dynamic tests, it was found that damping ratios of the OP particles included samples were improved by 70% at OP content of 10 wt%, while first-mode natural frequency was reached optimum value at 5 wt% of OP particles, indicating better chemical compatibility at this weight content, and further incorporation of OP particles into the epoxy resin resulted in reduction for both of mechanical and dynamic properties as a result of particle aggregation effects between OP particles-epoxy resin-fiber interfaces.

“…15 It was found that the loss factor, h, obtained via the hysteresis loop method was linearly dependent only on the applied excitation frequency and was independent of the preloading and the stress amplitudes. 16 In Bulut et al, 18 the results revealed that the position and the percentage of the fibres in composites were the most effective parameters for natural-frequency and damping characteristics. Even in cutting, the amount of wooden reinforcement in wood-plastic composites affects the shape of the formed chips.…”

The present work contributes to the research on the damping properties of fibre composites through an experimental approach by using the free damped vibration measurement based on impulse-force system response, the developed measurement stand and laser Doppler vibrometry. Moreover, the influence of the material configuration on the damping properties was investigated and was compared with conventional homogeneous isotropic materials. The measurement was based on the analysis of flexural vibrations generated by the Dirac impulse force, as well as on the free decayingvibrations response; the time-and frequency-domain modal identification was employed. The fibre composites were represented as layered bidirectional long carbon-and glass-fibre composites (laminates) with different material configurations and as short carbon-fibre composites.

“…[18][19][20][21] Thus far, a number of studies have confirmed the effectiveness of this method. [22][23][24][25][26][27][28] For instance, a study conducted by Yeter et al [29] studied the hybridization effect on the buckling characteristics of various fiber-reinforced plates. They reported that the buckling characteristics of composite plates were affected by the hybridization as well as the fiber stacking sequence.…”

In the present study, the effects of graphene nanoplatelets (GNPs) contents on the axial and lateral buckling behavior of carbon/aramid hybrid-woven epoxy nanocomposites were investigated. The composite plates were fabricated with different concentrations of GNPs (0.1, 0.25, and 0.5 wt%) by vacuum-assisted hand lay-up method. The addition of GNPs has resulted in enhancement in axial and lateral critical buckling loads. The maximum enhancement in both axial and lateral critical buckling reached with 0.1 wt% GNPs addition. These percent enhancement values in axial critical buckling loads were 25.7%, 5.2%, and, 14% with fixed-fixed, fixed-free, and free-free boundary conditions, respectively. For lateral critical buckling load, the maximum enhancement was recorded as 20.6% compared to the pure control sample. Also, with the further addition of GNPs, critical buckling loads decreased, which is interpreted because of the agglomeration of GNPs. The failure surfaces were then observed with scanning electron microscopy to examine the link between the buckling behavior and failure types of the composite samples.
