Effect of clay nanoparticles on the mechanical and vibration characteristics of intraply aramid/carbon fiber reinforced epoxy composite

Abstract

In the present contribution, the tensile, flexural, vibration and damping properties of intraply aramid/carbon fiber reinforced epoxy composite with the effect of clay nanoparticles inclusion have been investigated. Seven clay nanoparticles contents of 0, 1, 2, 4, 6, 8, and 10 wt% were used to produce the composite laminates. The samples were produced and experimented in accordance with ASTM standards. The standards ASTM D 638, ASTM D 790, and ASTM E756 were used for tensile, flexural, and vibration tests, respectively. Vibration characteristics were calculated using experimental modal analysis. Half power band‐width method was applied to evaluate damping responses of first natural frequency modes of the composite samples. The results indicated that the high improvement of tensile and flexural strength was obtained at clay nanoparticle contents of 1 and 2 wt% with increment of 13.1% and 28.2%, respectively. The highest values of natural frequency, storage modulus, lost modulus were obtained at clay nanoparticle contents of 10, 1, and 2 wt% with increments of 23.4%, 20.7%, and 11.6%, respectively.

Effect of hybrid fillers of Mg–Al layered double hydroxide and nanoclay on the mechanical behavior and formability of glass laminate AA5052‐reinforced epoxy composites

“…Furthermore, it was noted that the energy absorption of hybrid filler was higher than that of FML with LDH filler and FML without any filler material, as shown in Figure 9A. From previous studies, [ 25,21 ] it was understood that the use of LDH as filler lowered the impact energy absorption capacity of the FML, and incorporation of NC filler enhanced the impact energy absorption of the FML when compared to laminate without filler. Thus, the utilization of LDH + NC hybrid filler induced an intermediate impact energy absorption capacity of the FML.…”

“…Similar trend of UTS was observed in FML with individual LDH and NC filler and FML without any filler material in the perspective of the rolling direction. [ 21,25 ] The highest value of YS of 148 MPa was observed for FML with 4 wt% of LDH + NC in 0° orientation amidst all the FML samples in any orientation. The lowest YS value of 88 MPa was noted for the FML with 5 wt% of LDH + NC hybrid fillers in 45° rolling direction.…”

“…[ 20 ] Furthermore, the natural frequency, storage modulus, and lost modulus of the aramid/carbon fiber‐reinforced epoxy composites were improved with the amount of NC filler. [ 21 ] The modified glass fiber (GF) fabric/epoxy composites with multi‐walled carbon nanotube and montmorillonite fillers increased the interlaminar shear strength significantly comparing to the unfilled composites. [ 22 ] Wan Ramli et al reported that the interfacial bonding between the fiber and the matrix was complemented by adding 5 wt% of NC in Napier fiber‐reinforced epoxy composites.…”

“…Al-Furjan et al [16] presented dynamic stability of viscoelastic carbon nanocones under the thermal and magnetic loads on the basis of Mindlin theory. Alsaadi et al [17] studied flexural, tensile, damping and vibration of carbon fiber reinforced epoxy composite. Keshtegar et al [15] studied dynamic instability analysis in hybrid polymer nanocomposite beam on the basis of exponential shear deformation higher order beam theory.…”

Investigation of toughening effect of biomass‐derived SiCB on basalt fiber‐reinforced unsaturated polyester composites

“…[29] From previous reports, several kinds of particles as second phase reinforcement have been used for the fiberreinforced polymer composites nowadays, such as nano-TiO 2 , graphene, clay nanoparticles, cellulose nanocrystal, carbon nanotubes and nano-organic montmorillonites, and so on. [30][31][32][33][34][35][36] These particles are complex and expensive in manufacture. While the silicon carbon black (SiCB), produced by selective pyrolysis and directional smash of rice husks, is simple and cheap in production.…”
