“…Lattice-core sandwich structures. Venkatachalam et al [51] obtained two mathematical models for the flexural stress and stress intensity factor of sandwich structures with a PP honeycomb core and flax fiber-reinforced polymer face sheets using the Taguchi method and experimental data. Fu and Sadeghian [52] comprehensively analyzed the flexural and shear properties of sandwich beams made of a bio-based epoxy resin, unidirectional flax fibers, and two different types of phenolic-treated kraft paper honeycomb cores, namely a hollow core and PU foam-filled core.…”

In recent years, concerns about environmental pollution have led to the development of natural fiber sandwich structures as alternatives to petroleum-based ones. This paper reviews various studies on sandwich structures composed of non-wood cellulose-nature fibers. These fibers mainly include flax, hemp, jute, kenaf, sisal, coir, and bamboo. The studies are classified based on the type of fibers, the components in which they are used, and experimental tests/numerical investigations. Furthermore, a few suggestions for future research in the field of eco-friendly sandwich structures are made.

“…These conclusions were based on taking into account many factors, including fabric orientation, the type of alkali treatment, the type of resin, and its impact on the fracture and flexural behaviours of sandwich panels reinforced with flax fibre. There is relatively little variation in flexural stress according to the alkali treatment method [26]. Based on Adeniyi et al's findings, alkalization with NaOH was the most widely used kind of treatment.…”

PVC (polyvinyl chloride) is a tough polymer used in applications, including plumbing and construction materials. As natural fibre-reinforced composites have more advantages over conventional synthetic composites, this paper focuses on the fatigue analysis of PVC composite which is reinforced with coir fibre. The influences of three input parameters, namely, the size of the coir fibre, coir fibre content, and the chemicals that are used in the treatment of coir fibre on the fatigue life of the composite are examined. In the response surface model (RSM), Box-Behnken designs (BBD) are employed for the preparation/analysis/optimization of the samples. ANSYS software is used to perform the fatigue analysis of different samples containing various combinations of the parameters. To determine the effects of various input parameters on the fatigue behaviour of composites, ANOVA is employed to determine their optimal levels. Regression equations are established to determine the fatigue limit. When treated with triethoxy(ethyl)silane, coir with a concentration of 6 wt.% and a particle size of 75 μm exhibits a maximum fatigue limit of 2.819 MPa.
