Agro-wastes have a huge potential to be utilized as lignocellulosic reinforcements in polymer composites. This will not only play an important role in waste management but will also strengthen sustainable production. In the present work, pine cones and wood apple shells were utilized as fillers along with areca sheath fibers in bio-based epoxy resin for fabricating a novel hybrid composite wherein the effect of these fillers in laminated composites has not been explored to a greater extent. The impact of reinforcing both types of fillers in different loadings (5, 10, and 15 wt.%) on various properties of composites was investigated. Physical properties like density, void fraction, mechanical properties comprising of tensile, flexural, interlaminar shear strength (ILSS), and hardness along with morphology and moisture absorption behavior of composites were investigated. The mechanical properties of the fabricated composites were influenced by the structure (coarser/finer) of fillers and their chemical composition. The mechanical results for the composites revealed that incorporating wood apple shell fillers resulted in the maximum rise in tensile (23.97%), impact strength (16.81%), and interlaminar shear strength (31.64%), while the incorporation of pine cone fillers resulted in the maximum rise of flexural strength along with Young's (35.4%) and flexural modulus (32.81%). A reduction in moisture absorption was observed on the addition of both types of fillers up to a certain filler loading. The investigations demonstrated a noticeable enhancement in mechanical and physical properties of the fabricated composites on reinforcing micron size fillers.

“…In a different study, Khorasani et al studied the thermal and mechanical buckling properties of epoxy skins reinforced by honeycomb microplates integrated with FG-GNPs. 60 It was revealed that the critical buckling load was reduced with the increasing GNP's height to length and GNP's length to width ratios. Additionally, they observed that without the addition of GNPs, critical buckling load increased for one-dimensional force intensity distribution, while it decreased for two-dimensional force intensity.…”

In recent years, nanocomposites prepared by dispersing biopolymer with nanofillers (bionanocomposites) have attracted a growing attention, since they present remarkable electrical, optical, mechanical and thermal properties, which make them useful for various technological applications. However, the understanding of the diversity of application areas of bionanocomposites can only be specified by advanced characterization techniques. As well known, the illumination of the main characteristics of bionanocomposites makes them more eligible for their potential use. Therefore, the characterization techniques given in this review fall into the two main categories: the morphological and mechanical characterizations. Morphological characterization techniques presented include the most popular techniques atomic force microscopy, scanning electron microscopy and transmission electron microscopy. Mechanical characterization techniques presented here include tensile test and dynamic mechanical analysis. Additionally, thermal stability bionanocomposites determined by thermogravimetric analysis is briefly touched.

“…For simplicity reasons, Equation (1) can be rewritten in a more compact For this sandwich structure, we propose and compare a thermomechanical model based on four different kinematic assumptions, namely, the third-order shear deformation theory (TSDT), the hyperbolic shear deformation theory (HSDT), the sinusoidal shear deformation theory (SSDT) and the exponential shear deformation theory (ESDT). Based on these kinematic assumptions, the displacement field for an arbitrary point in the mid surface is defined as [20,21].…”

Due to the widespread use of sandwich structures in many industries and the importance of understanding their mechanical behavior, this paper studies the thermomechanical buckling behavior of sandwich beams with a functionally graded material (FGM) middle layer and two composite external layers. Both composite skins are made of Poly(methyl methacrylate) (PMMA) reinforced by carbon-nano-tubes (CNTs). The properties of the FGM core are predicted through an exponential-law and power-law theory (E&P), whereas an Eshelby–Mori–Tanaka (EMT) formulation is applied to capture the mechanical properties of the external layers. Moreover, different high-order displacement fields are combined with a virtual displacement approach to derive the governing equations of the problem, here solved analytically based on a Navier-type approximation. A parametric study is performed to check for the impact of different core materials and CNT concentrations inside the PMMA on the overall response of beams resting on a Pasternak substrate and subjected to a hygrothermal loading. This means that the sensitivity analysis accounts for different displacement fields, hygrothermal environments, and FGM theories, as a novel aspect of the present work. Our results could be replicated in a computational sense, and could be useful for design purposes in aerospace industries to increase the tolerance of target productions, such as aircraft bodies.
