“…Furthermore, an easy and inexpensive availability, processability and non-toxicity of NC is of high importance among other things, as it has been reported in Dasan 20 and Bensadoun et al, 21 resulting in commercial attention towards these materials. Nowadays, NC is increasingly used in various industries, for example, in automotive, packaging, coating and paints, electronics and aerospace, [22][23][24] to enhance cost-effective, specific material properties, such as stiffness, 25 strength, 26 limited flammability and thermal stability, 27 fracture toughness 28 and viscosity. 29 Furthermore, NC is also of electrical non-conductive nature.…”

The effect of nanoclay on various material properties like damping and strength of typical thermoset polymers, such as epoxy and vinyl ester, was investigated. Different environmental conditions typical for high-voltage transmission pylons made of composite materials were taken into account. Resin samples were prepared with various clay weight fractions ranging from 0% to 3%. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction and rheological analysis were used to study the morphology and the structure of the nanocomposites. For all nanoclay-modified thermoset polymers, the morphology was found to be of exfoliated structure mainly. Static, uniaxial tensile tests showed that the addition of nanoclay to thermoset polymers led to a beneficial effect on the stiffness, whereas the tensile strength and ductility significantly decreased. When exposed to different environmental conditions, nanoclay was found to have a positive influence on the dynamic properties, analysed by a dynamic mechanical thermal analysis. The addition of nanoclay to the thermoset resin led to an increase of the damping properties by up to 28% for vinyl ester and up to 6% for epoxy at 220°C. The dielectric properties were evaluated by electrical breakdown strength tests resulting in 11% better insulating behaviour for nanoclay-modified vinyl ester.

“…For variable boundary conditions, geometric parameters, and material qualities, the theory is used to quantify the impacts of axial distributed load/terminal force and temperature fluctuation on free vibration and buckling. At a very low computing cost, the current theory can accurately estimate the natural frequencies and buckling capabilities of multilayered beams [11][12][13][14][15][16][17][18]. e composite's mechanical characteristics are scrutinized for quality and durability.…”

Composite fiber reinforcement is one such proficient material that substitutes for useful applications for conventional and polyester blends where little weight and thus less energy conservation is required. This study highlighted the importance of recently discovered Agave Angustifolia marginated (AAM) fibers extracted by a manual process from AAM plants. This paper observes the various properties of the mechanical and moisture intake characteristics of AAM fiber and compares these to other naturally occurring fibers. Using isophthalic polyester resin, the mixed chopped AAM fiber-reinforced composite is prepared and detailed preparation techniques are presented. During physical composite testing, fiber pull-outs on the broken samples were investigated. Additionally, the experimental evidence demonstrates that increasing the volume fraction helps to increase the tensile, bending, and modulus of the AAM fiber composite. The chopped fiber isophthalic polyester reinforcement reaches its improved tensile strength and modulus at a 25% Vf about the 20 mm length of the fiber.

In this study, the effect of wood powder and nanoclay particle content on composites’ mechanical behavior made with polyethylene matrix has been investigated. The wood flour as a reinforcer made of wood powder was at levels of 30, 40, and 50 wt.%, and additional reinforcement with nanoclay at 0, 1, 3, and 5 wt.%. Furthermore, to make a composite matrix, high-density polyethylene was used at levels of 70, 60, and 50% by weight. Wood-plastic composite (WPC) specimens were manufactured in injection molding. After preparing the specimens, tensile and bending tests were performed on samples. The mechanical properties such as tensile and flexural strength and flexural modulus were measured. Results showed that nanoclay particle content increases flexural modulus, flexural strength, modulus of elasticity, and tensile strength. The experimental test results show that Young’s moduli increased with the volume of wood flour. The biggest modulus of elasticity was achieved in the samples having 50 wt.% of wood powder. Furthermore, the highest value of tensile strength was achieved at the level of 30 wt.%. The highest flexural strength was for the sample containing 50% wood powder by weight. Additionally, a numerical model was made utilizing the Abaqus software using the finite element method (FEM). Comparing the numerical and experimental results, it was found that they are compatible in the linear-elastic and plastic state of the material. There are no crucial differences between experiment and FEM.
