This work aims to investigate the effect of SiO 2 nanoparticles on the mechanical properties of pineapple leaf ber (PALF) epoxy hybrid composites. The compression molding process was used to create the composite. To achieve the aforementioned goals, the blends were made using 25% PALF and varied weight proportions (3wt%, 6wt%, and 9wt%) of SiO 2 nanoparticles. Tensile, bending, impact, interlaminar shear, shoreline D hardness, and dynamic mechanical analysis were all evaluated. SEM was used to examine the morphology of the materials, and an FTIR spectrometer was used to look for the presence of organic chemicals in ber-reinforced composite materials. The ndings show that adding 25% PALF ber and 6% SiO 2 nanoparticles (D-type) to the epoxy polymer improved the thermal and mechanical properties of the composites. It can be attributed to the improved interaction and homogeneous dispersion of the llers and epoxy polymers. Moreover, the water uptake parameters of all samples were studied. The ndings showed that the inclusion of reinforcements boosts the water uptake of the composite signi cantly. The initial deterioration rate of the SiO 2 -incorporated hybrids is almost the same, at about 400°C, which is considerably greater than that of the beginning breakdown temperatures of PALF (300°C), according to the thermography study. This might imply that the ber and polymers form a stronger bond, reducing polymer movement and increasing the thermostability of the combination.

“…The TGA curves show similar trends for all the composites which signifies that addition of HGMs to coir/epoxy composite does not appreciably affect their thermal stability (Figure 5D). Kavya et al 44 also observed that the thermal properties of coir fiber epoxy composite was not significantly changed due to incorporation of inorganic fillers. In another study, thermal property of the composites was insignificantly varied with varying weight percentages of reinforcements 45 .…”

Nowadays, various types of biocomposites are being developed using different types of natural fibers and polymers to fulfill the requirement for sustainable products. Recently, the addition of fillers in biocomposites has been a useful approach to improve their performance and overwhelm their limitations. The hollow glass microspheres (HGMs) were uniformly distributed into epoxy using a magnetic stirrer and subsequently, a hand lay‐up technique was employed to produce the HGMs/coir/epoxy composites under a static loading condition. In the current study, the effect of varying weight percentages (i.e., 1, 3, and 5) of HGMs on the mechanical, dynamic mechanical, and thermal properties of coir/epoxy composites has been studied. Further, morphological analysis of fractured surfaces of samples was also performed. The results suggested that the addition of HGMs caused a significant improvement in the tensile and impact properties of the composites but could not extensively improve the flexural strength, thermal stability, storage modulus, and loss modulus. There was a significant improvement of 80.5% in tensile strength and 24.7% in impact strength of composites after the addition of 1 wt%. HGMs. Further, tensile and flexural moduli were found to be gradually improved with increased HGMs weight percentages in the composites.Highlights Development of HGMs/coir/epoxy composites.

“…The orientation and plastic flow of the HDPE were observed in the few composite places. [63][64][65] Because the polar groups in CC resisted the nonpolar groups in HDPE, the CC particles were not evenly distributed throughout the HDPE matrix and were separated from it. The dispersion might be enhanced even further by lowering the size of the fillers.…”

This work aims to incorporate lignocellulosic coconut coir (CC) fillers into the HDPE matrix for domestic cloth clip product development where the strength is less significant. The structural, mechanical, and thermal properties of HDPE composites with varying weight fractions of CC fillers (10, 20 wt%) were investigated. The die for product development was designed through Pro-E software and manufactured with relevant machining processes. The composites were fabricated through the injection molding technique as per ASTM standards.Using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis, the microstructure and various proportions of elements present in the composites were investigated. The presence of different functional groups and their vibrations were identified through the Fourier-transform infrared spectroscopy (FTIR) technique. The experimental mechanical results reveal the positive effect of CC fillers in the HDPE matrix, and the results were a maximum of 20 wt% CC filler incorporation. The filler reinforcement has little effect on the thermal degradation behavior since the step of deterioration is not changed appreciably. Nevertheless, the initial degradation temperature was affected by the presence of CC fillers. Depolymerization and dehydration of diverse ingredients correspond to different endothermic peaks in the DSC curve. Based on the characterization results, the 20 wt% CC filled-loaded partial eco-composite was selected for cloth clip product development.
