“…The composite samples were prepared using a hand layup method followed by the compression molding technique. The essential quantities of the fiber, epoxy, and filler material were weighed and designed using equation (1) [50]. Epoxy and the nanofiller PbO were mixed to get a homogeneous mixture using a mechanical stirrer with 2000 r/min speed.…”

In the present study, the significance of nanofiller lead oxide (PbO) on the dynamic mechanical analysis (DMA) and interlaminar shear strength (ILSS) performance of luffa fiber–reinforced epoxy composites was investigated. The epoxy matrix was altered with nanofiller PbO of different weight percent through a mechanical stirring process. The PbO-added luffa fiber epoxy composites were made through hand layup preceded by the compression molding method. The prepared composite samples were investigated for ILSS and DMA. The test results lead to the inference that the 1.25 wt% PbO nanofiller–added composite samples attained 25%, 17%, and 55% of higher loss modulus, storage modulus, and ILSS, respectively, as compared with the other prepared samples. The morphological investigation was conducted on the fractured surface of the interlaminar tested samples. The micrographic images show the bonding nature of the luffa fiber with the epoxy matrix, fiber breakage, and fiber pullouts. The characterization studies such as FTIR, XRD, and EDX were conducted on the fabricated composite samples. The XRD studies show that the rise in weight percent of the nanofiller PbO enhances the crystallinity of the composite samples. Moreover, the composite sample prepared with 1.25 wt% nanofiller PbO can be used to prepare low-cost roofing materials for sustainable housing projects.

“…The addition of fillers to the hybrid composites added improved mechanical properties. Lignite fly ash was used as filler in the Sansevieria roxburghiana fiber-reinforced epoxy composites, and tensile, flexural, and impact strength was increased in the ratios 38.33%, 41.34%, and 33.56% [10]. SiC was used as filler material in hybrid fiber-reinforced composites, and it provided a strong effect on various properties [11].…”

In this research work, the mechanical properties of hybrid composites reinforced with woven carbon fiber mats particulated with natural rubber powders as fillers in the epoxy resin matrix were investigated. The specimens were prepared by the hand-layup process followed by a vacuum bag moulding process. The vacuum moulding reduces the voids or cavities in the hybrid composites. The natural rubber powder was added in different weight proportions (5%, 10%, 15%, and 20%), and carbon fiber is added in 20% for all the specimens. Experiments such as tension testing, flexural testing, water absorption/acid corrosion/base corrosion tests, dynamic mechanical analysis (DMA), and scanning electron microscopic (SEM) analysis were conducted to evaluate the epoxy carbon rubber (ECR) composites. The tensile and flexural test findings demonstrated that the addition of 10% natural rubber particles gave better results as compared with other proportions. The water/acid/base absorption test findings reveal that the ECR composites are not affected by water/acid/base. The DMA teat findings show that ECR composites having 10% natural rubber have higher damping factor, storage, and loss modulus. The SEM analysis shows that ECR hybrid composites with 10% rubber particles contained a uniform distribution of rubber particles over reinforcement, and also, there were no cracks and voids. According to this research findings, ECR hybrid composites with 10% natural rubber particles prepared during the vacuum bag moulding process can be used to prepare aerospace interior components.

This study examines the effects of lignite fly ash as a filler on the tribological and mechanical performance of a Calotropis gigantea fiber–epoxy composite. The investigation results show that the Calotropis gigantea fiber/epoxy composite with 2 wt.% lignite fly ash nanofiller added had better tensile strength, interlaminar shear, impact strength, and flexural strength than the control sample by 29.83%, 58.17%, 69.16%, and 11.41%, respectively. The manufactured composite samples were subjected to tribological tests, such as the friction coefficient and specific wear rate under dry sliding conditions with various process variables, such as sliding speed (1–3 m/s), functional load (10, 20, and 30 N), and sliding distance (1000 m). The results show that adding 3 wt.% nanofiller lignite fly ash to the Calotropis gigantea fiber/epoxy composites greatly improves the specific wear rate and friction coefficient. Additionally, the performance of the Calotropis gigantea fiber/epoxy composites in absorbing moisture was enhanced by the inclusion of the nanofiller lignite fly ash 2 wt.%. Likewise, the composite sample developed with the ideal nanofiller lignite fly ash with Calotropis gigantea fiber may be used for sustainable brake materials owing to its superior mechanical and tribological qualities.
