“…4 and 5 illustrate the force-time and force-displacement histories of different stacking sequenced glass (G), basalt (B) non-hybrid/hybrid fiber reinforced composites with respect to GnP filler content at 30 J. The sudden drop in contact force after first peak in force-time curve indicates the beginning of delamination or cracking damages as reported by many researchers [31,32]. , respectively.…”

“…In addition, glass fiber hybridization contributed a positive effect on the basalt/glass hybrid composite structures in terms of flexural and tensile strength. When glass fiber is placed at outer the skin, and basalt fiber is in core in the middle, hybrid composite laminates have shown higher tensile/flexural strength compared to other hybrid configuration due to higher tensile/flexural strength and modulus of glass fibers [32]. It was also noted that flexural strain and modulus values were reached their maximum values with 0.1 wt% GnP filler, this could be attributed the better interfacial stress transfer at fiber/matrix/GnP particles, and these considerable improvements in flexural and tensile strength of composite samples filled with 0.1 wt% GnP suggest the improved interfacial bonding between fiber and matrix material mostly due to large surface area of GnP particles.…”

In the present study, hybrid glass/basalt fiber composites containing nanographene (GnP) were manufactured for investigation of low velocity impact properties at the impact energy of 30 J. Also, their flexural and tensile properties were experimentally characterized. During the experiments, both laminate configurations as basalt and glass at outer and inner skins were treated for impact and mechanical tests. Failure mechanisms were analyzed with taking photographs over the front and rear sides of the samples and SEM observations on the impacted region after the impact tests. Results from this study indicated that incorporation of GnP at 0.1 wt% revealed a significant improvement in impact and mechanical properties indicating the better load transfer between GnP-matrix resin-fiber interactions.

“…This composite is also characterized by the lowest Young's modulus among all of the tested materials. The results described in the literature [21] show that the composites reinforced by Dyneema fibers deformed to a greater extent than the composites reinforced by E-glass fibers. The comparison between the composites reinforced by Dyneema and E-glass fibers presented in the literature [21] showed also that the composite reinforced by Dyneema fibers absorbed much more impact energy.…”

The comparison between the composites reinforced by Dyneema and E-glass fibers presented in the literature [21] showed also that the composite reinforced by Dyneema fibers absorbed much more impact energy. Based on the mentioned paper and observed damage (deformation of the sample), the authors suppose that the composite reinforced by polyethylene fibers absorbed a much higher amount of the impact energy than the other tested composites.…”

Low Velocity Impact Response and Tensile Strength of Epoxy Composites with Different Reinforcing Materials

et al. 2020

This paper presents the results of research concerning multilayered epoxy composites reinforced with different materials. The strength of multilayered composites depends, to a large extent, on the reinforcing material. The authors decided to compare the low velocity impact response and perform tensile strength tests on several composites, to ascertain the mechanical properties of the prepared composites. Five different reinforcing materials were provided for the research (two fabrics made from aramid fibers, two fabrics made from carbon fibers and one fabric made from polyethylene fibers). The composites were manufactured by the vacuum supported hand laminating method. The low velocity impact response tests were conducted with the use of a pneumatic launcher. Three strikers with different geometry (conical striker, hemispherical striker and ogival striker) were used. A comparison of the resulting damage to the composites after the impact of the strikers was based on the images obtained using an optical microscope; tensile tests were also performed. The experimental investigation showed significant differences in the mechanical properties of the composites, depending on the applied reinforcing material. It was found that, as a result of the impacts, less damage occurred in the composites which were characterized by a lower Young’s modulus and a higher tensile strength.

In this study, the low velocity impact effect of glass fiber‐reinforced laminated composites reinforced with nanoclay and boric acid was investigated. Nanoclay, boric acid, and interlayer hybrid composites were produced at 0 (pure), 0.5, 1, and 1.5 wt% with respect to epoxy resin. Laminated composites were obtained by the hand lay‐up method. Impact tests were applied to the specimens by releasing the weight. Tests were carried out with impact energies of 30, 40, 50, and 60 J to evaluate the behavior of composites under loading result in rebounding. Nano reinforcement generally increases the maximum reaction force while decreasing the impact duration, maximum displacement, and absorbed energy. As a result of all the tests performed, the reaction force increased up to 53% compared to the pure specimen, while the absorbed energy, impact duration, and maximum displacement values decreased up to 21%, 36%, and 12%, respectively. The results of the hybrid specimens in the interlayer sequence provided more changes compared to the mono‐reinforced specimens (i.e., nanoclay or boric acid). The hybrid specimen with a reinforcement ratio of 1.5 wt% impact face boric acid exhibited the greatest enhancement in impact resistance among all the tested specimens. The reaction force, which is an indicator of resistance, increased by 44%, 35%, 51% and 34% from energy level 30 to 60 J, respectively. Furthermore, the specimen exhibited the lowest values for absorbed energy, maximum displacement and impact duration.
