“…Te fllers are to form agglomerates on the processed specimens with maximum loadings. It is widely acknowledged that proper fller dispersion in the matrix is critical for optimal mechanical properties [17,22,23]. It is well known that as fller loading increases, so does the ability to agglomerate.…”

Fibre-reinforced polymers (FRPs) are composite materials of plastics reinforced with fibres. Cars, sea, aeronautics, and foundation projects progressively utilize fibre-reinforced polymers. This study aims to study the effect of adding multiwalled nanotubes fillers into the hybridized jute-glass FRP composites and their relative properties. This study uses multiwalled nanotubes (MWCNTs), and particles-hybrid jute-glass composites containing jute fibre chopped layer mats, woven glass mats, epoxy resin, and multiwalled nanotubes fillers were created using the hand layup method. After adding multiwalled nanotubes fillers in various weight proportions, the mechanical behaviours of fibre-reinforced polymers were analysed. The mechanical behaviours of laminated composites were tested using the ASTM standard; the following properties are tensile, flexural, and impact strength. The multiwalled nanotubes with 6% wt. attained the maximum mechanical properties compared to the 2 and 4 wt. % of MWCNTs. The E-based specimen contributes the most to the different types of specimens, with a contribution of 24.21% for tensile, 25.03% for flexural, and 24.56% for impact. The microstructures of hybrid composites were studied using a scanning electron microscope.

This research focused on investigating the mechanical, wear, and fatigue behavior of an epoxy composite toughened with corncob biosilica (CCB) and prickly pear fiber (PPF). The primary aim of this research was to improve the load bearing effect of high‐brittle matrix by adding eco‐friendly fiber and particle. The surface treatment on the fiber and particle was done using an amino silane, 3‐Aminopropyltrimethoxysilane (APTMS). The natural fiber composites are prepared by hand layup process and characterized in accordance with ASTM standards. The experimental results indicated that the addition of fiber and particles increased the tensile and flexural strength up to 61% and 50%, respectively. Similarly, it is noted that the biosilica particles improved the bonding and reduced the rate of wear of composites, as well as lowered the stress intensity factor. A lowest wear rate of 0.037 and COF of 0.38 were noted for EFC2 composite designation. The morphological study of the fractured composites revealed improved fiber adhesion to the matrix. This reduced intensity of stress, increased wear resistance and higher fatigue life ensures the composite's application in structural and industrial applications.

Sisal fiber reinforced nanosilica and cardanol oil toughened epoxy composites were prepared and characterized in this present work. The main aim of this study was to understand the importance of adding cardanol oil and nanosilica to sisal-reinforced epoxy composites in enhancing the load bearing, thermal stability, and antimicrobial properties. The composites were fabricated by the hand layup process and specimens were cut using a water jet machine. The composites were tested using the respective ASTM standards. The results found that the blending of cardanol oil makes the epoxy less brittle and the composites are environment friendly. Similarly, nanosilica with sisal fiber in cardanol oil blended epoxy composites showed improved mechanical properties. The highest tensile strength and modulus were found to be 56% and 64% than pure epoxy resin. The maximum impact resistances and hardness values observed for the composites are 6.48 J and 91 shore-D. Moreover, improved fatigue life counts were observed for composite designation ECN2, which contains 1.0 vol% of nanosilica, but also a decrement in it if the volume percentage was increased to 2.0. The antimicrobial properties improved with the increment of nanosilica and cardanol oil content. These eco-friendly, mechanically toughened biocomposites could be used in drug and food storage, automotives, drones, structural, and sports goods as well as in household appliances manufacturing.
