“…It is known that energy dissipation in a composite material depends on parameters such as matrix and fiber types, matrix-fiber interface, nanomaterials additive, stacking sequence, fiber orientation etc. In a study conducted by Doddi et al, 3 pineapple leaf and basalt fiber reinforced composites were manufactured and effects of the fiber orientations of the outer basalt layers on the tensile, flexural and damping properties were investigated. It was revealed that composite specimens in which basalt fibers aligned in transverse direction exhibited best damping value.…”

“…For this purpose, many researchers have conducted studies to determine dynamic properties and to find out ways to increase the damping performance of the materials. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] Damping is defined in different ways such as energy dissipation or conversion of mechanical energy to thermal energy.

It is highly important to determine how mechanical and dynamic properties of composite materials will change after impact loads considering the coupled effects of composite design parameters. For these reasons, three-point bending and vibration tests have been carried out for the carbon fiber reinforced thermoset and thermoplastic composites with various stacking sequences before and after low velocity impact, and it is expected that these results achieved from the current study will be beneficial for applications where high damping and impact resistance are demanded together. In this context, vibration tests were carried out under free-free boundary conditions, and their natural frequencies, flexural moduli and structural damping were obtained. Furthermore, three-point tests were conducted in the elastic region with 1 mm/min crosshead speed using a universal test machine, and thus flexural moduli of the composite specimens were obtained. The results were validated by comparing the flexural moduli obtained from the both vibration and three-point bending tests, found to be reliable and comparable. As a result of the current study, it was concluded that woven fabric reinforced composite specimens exhibited 50% higher specific damping capacity (SDC) but 70% lower flexural modulus than unidirectional specimens thanks to biaxially fiber alignment. On the other hand, specific damping capacities of the thermoset and thermoplastic composites with different stacking sequences have been examined, and it was observed that thermoset specimens exhibited unexpectedly 192% higher SDC compared to the thermoplastics. This was interpreted as even though thermoplastics are normally expected to exhibit more damping than thermosets, stacking sequence being more effective on damping responses. Apart from that, although there were slight changes in material properties due to degradation in structural integrity after 2 m/s and 3 m/s low-velocity impacts, it was not found to be significantly effective due to the limited damage areas.

“…Carbon fibre reinforced epoxy composite (C-epoxy) is a subclass of carbon fibre reinforced plastics (CFRPs) which are excessively being used nowadays in the area of aerospace, automotive and underwater applications to replace conventional metallic materials because of their high specific strength, low density, high stiffness, high rigidity, good corrosion resistance 1 and high damping characteristics. 2,3 However, fibre reinforced composites are brittle with poor resistance to crack propagation. 4,5 Hence additional tougheners are required to eliminate the catastrophic failures of the structures when subjected to sudden loads.…”

The objective of this research is to develop a hybrid composite with a unique combination of features such as tensile, flexural and Interlaminar shear strength (ILSS) properties. It is a present need for components used in underwater, aerospace, defence and automotive applications, as parts are subjected to a variety of loading conditions, including tensile, bending and shearing. Carbon fibre reinforced epoxy (C-epoxy) composite is modified by adding epoxy terminated butadiene acrylonitrile (ETBN) liquid rubber and amino-functionalized multi-walled carbon nanotubes (Af-MWCNTs). With the addition of ETBN, the tensile, flexural and ILSS properties were improved by 38%, 46% and 80%, respectively. The addition of 0.5wt% of Af-MWCNTs improved the tensile and flexural strengths by a maximum of 59% and 61%, respectively. In contrast, the maximum improvement in ILSS of 120% was obtained at 1.0 wt.% of Af-MWCNTs. The unique combination of C-epoxy-ETBN-Af-MWCNTs led to the formation of the serrated surface at the fibre matrix interface, which caused improved energy absorption. The toughening mechanisms which are responsible for the improvement in properties are discussed and the results are validated through finite element analysis (FEA).
