“…We find that the values are between 0.116 g/cm 3 and 0.343 g/cm 3, and it is comparable to the bulk density of RV fibers which evolves from 0.128 g/cm 3 to 0.237 g/cm 3 during the study conducted by Sikame et al [16]. e RVP can be considered as a light material.…”

“…Figure 7 shows the evolution of the bulk density along the RV stem. We noted also that the values increase from the center to the periphery at any cross section along the stem and they are between 0.1 g/cm 3 and 0.46 g/cm 3 . e density of the matrix of RVP is less than that of polymer generally used as matrix during the elaboration of composite [38,40].…”

In this paper, the physicochemical and mechanical properties of Raffia vinifera pith (RVP) are discussed. Microscopic observations have shown that the structure of the RVP is similar to that of a composite consisting of natural fibers. The effective area ratio of Raffia vinifera (RV) fibers was evaluated along the raffia stem using ImageJ software, and it decreases from the periphery to the center. Energy dispersion spectrometer (EDS) analysis shows that RVP is essentially composed of carbon and oxygen. Densities of RVP and its matrix were determined using Archimedes’ principle and law of mixtures, respectively; from the results obtained, they can be considered as one of the lightest materials. Young’s modulus of RVP has been obtained from tensile and bending tests, while that of matrix has been obtained using the law of mixtures during tensile tests. RVP has better specific properties, and the results of the matrix properties show that we can easily select another matrix which has better properties than the case studied during the elaboration of composites.

The present work's target is to study the impact of fly ash or TiC nanoparticles or both on the characteristics of coir fiber epoxy hybrid composites. Mechanical characteristics like tensile, flexural, inter-laminar shear strength, impact strength, shore D hardness, and thermal stability or degradation characteristics were determined. The microstructure of the samples was observed from a scanning electron microscopy. It was observed that the addition of coir fiber, fly ash, and TiC nanoparticles in the epoxy polymer enhanced the mechanical and thermal characteristics of composites. It can be assigned to the better interaction and uniform distribution between the fillers and the epoxy polymer. Fillers acted a critical role in enhancing the characteristics of epoxy hybrid composites. Additionally, water absorption characteristics were also investigated for all specimens. A comparative examination was performed between various fabricated composite specimens. Results exhibited that, the water absorption of the composites improves considerably with the addition of reinforcements. Also, thermogravimetric analysis exhibited that the fabricated epoxy hybrid composites were stable thermally.

“…SEM is a characterization technique used to analyze the structure of broken surfaces caused by mechanical and physical loading. The morphological representations of the developed composites are examined with aid of SEM [34]. To investigate the interfacial characteristics of developed composite and the structure of fractured surfaces, SEM analysis was performed on the composite samples.…”

The main aim of this work is to investigate the effect of hybridization and the influence of tamarind nut shell powder (TNSP) on the properties and characterization of jute and hemp plant fibers reinforced composites by varying weight % of fibers. The composites are fabricated through the compression molding method and the properties such as tensile strength, tensile modulus, flexural strength, flexural modulus, Shore-D hardness, void content, and interlaminar shear strength (ILSS) of the hybrid composites are evaluated. The characterization studies such as Fourier transform infra-red (FT-IR) spectroscopy, water absorption behavior and scanning electron microscopy (SEM) analysis are also conducted. The results indicated that the hybrid composite samples 40:0 (jute: hemp) have the highest tensile, flexural, impact strengths as well as ILSS values. The void content of 20:20 (jute:hemp) composites was reduced owing to the good adhesion and compatibility of both the fibers with the matrix material.
