“…Furthermore, only a few studies devoted to free vibration characteristics of basalt or carbon fiber reinforced composites are seen in the literature. Bozkurt and Gökdemir (2018) examined the influences of basalt hybridization on the tensile and dynamic characteristics of carbon fiber reinforced composite laminates. It was demonstrated that the inclusion of basalt fiber resulted with an enhancement in damping properties and decrease in tensile characteristics of carbon fiber reinforced composite laminates.…”

The current work deals with an experimental investigation about the influence of cut-outs on dynamic characteristics of basalt/carbon hybrid fiber reinforced composite laminates. The composite samples have been fabricated via vacuum assisted resin transfer molding technique and cut-outs in the form of triangular, square and circular shapes with equal areas have been processed on them to systematically analyze the influences of cut-outs. The dynamic characteristics of the samples have been examined by conducting free vibration-damping tests and expressed in terms of natural frequency and damping ratio using the frequency response and time-acceleration response. The results show that the damping characteristics of the composite samples can be remarkably improved with the help of cut-outs which provide improvements approximately between 2.41% and 16.65% in damping ratio values. The maximum and minimum variations in damping ratio have observed for non-hybrid carbon fiber reinforced composite samples with triangular cut-out (T-C6) and hybrid basalt/carbon fiber reinforced composite samples with circular cut-out (C-B6), respectively. On the other hand, the presence of cutouts have led to decreases in natural frequency values as a result of reduction in stiffness caused by the cut-outs. This point out that employment of cut-outs can be a promising application to meet the natural frequency requirements of engineering systems constructed with hybrid fiber reinforced composite laminates.

“…The results showed that the flexural properties strongly depended on the reinforcing position of carbon and basalt fabric [10]. Bozkurt et al [11] experimentally investigated the effect of basalt fiber hybridization on vibration damping and tensile properties of carbon fiber/epoxy composites prepared using VARTM process. The results showed that incorporation of basalt fiber into the carbon fiber/epoxy composites significantly affected the tensile strength, tensile modulus and enhanced damping properties [11].…”

The effect of reinforcement material and manufacturing method on tensile, impact, and hardness properties of glass and basalt laminated composites were studied. Woven glass and basalt fabrics were used as reinforcements along with a thermosetting epoxy matrix to fabricate the laminate composites. The glass and basalt epoxy composites were made using hand layup with compression, vacuum bagging, and vacuum-assisted resin infusion methods. The characterization tests are performed as per the ASTM D638-10, ASTM D256, and ASTM D2240 standard respectively. The basalt epoxy composites show improved mechanical properties compared to the glass-epoxy composites. Further, hand layup, along with compression moulding and resin infusion methods, were found to be beneficial in improving the mechanical properties of the composites. Field emission scanning electron microscopic analysis conveyed the adhesion between fibers and resin as well as the voids retained within the matrix are the dominant factors that determined the mechanical properties of the laminated composites such as tensile, impact strength and hardness.

“…In the study conducted by Bozkurt and Gökdemir, 12 effects of using basalt fiber layers in between the epoxy/CF composite laminates was investigated. They indicated that although use of basalt fiber layers decreased the tensile strength and tensile modulus of the epoxy/CF composite laminates; increasing the basalt fiber layers increased the damping ratio of the laminates up to 61%.…”

The main objective of this study was to investigate contribution of the non-functionalized multi-walled carbon nanotubes on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber reinforced epoxy matrix composites. Epoxy/carbon nanotubes nanocomposites were produced by ultrasonic solution mixing method, while the continuous carbon fiber reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the specimens were evaluated by half-power bandwidth method; and the mechanical properties of the specimens were determined with three-point bending flexural tests, including morphological analyses under scanning electron microscopy. It was generally concluded that when even only 0.1 wt% carbon nanotubes were incorporated into neat epoxy resin, they have contributed not only to the mechanical properties (flexural strength and modulus), but also to the vibration behavior (damping ratio) of the epoxy. When 0.1 or 0.5 wt% carbon nanotubes were incorporated into continuous carbon fiber reinforced epoxy matrix composites, although they have no additional contribution to the mechanical properties, their contribution in terms of damping ratio of the composites were significant.
