“…The viscoelastic behavior of the material is examined using dynamic mechanical analysis (DMA) in terms of storage modulus (E′) and tan delta or loss factor over a range of temperatures [ 21 ] . Figure 3 illustrates the DMA of epoxy and its derived composites.in the glassy region, at low temperaturethe molecular chains are tightly packed, incredibly immobile, and have strong intermolecular contacts, it is discovered that composites in this region have the highest value of E′ as shown in Figure 3A.…”

In the current work, light weight epoxy bio‐composites are created for low‐cost technological applications using luffa aegyptiaca fiber and biochar particles derived from coco husk (CHB). This study aims to evaluate the effects of CHB particles added at different concentrations (3 vol% and 5 vol%) on the dynamic mechanical, ballistic and tribology behavior of epoxy composites constructed from luffa aegyptiaca fiber with different fiber loading (20%, 30% and 40 vol%). The composites are prepared using hand layup process provided with post curing operation. The combination of 3 vol% CHB particles and 40 vol% luffa aegyptiaca fiber having the improved viscoelastic properties by means of high storage modulus (5.05 GPa) and low loss factor (0.31). Moreover, this composite shows better ballistic properties in terms of low velocity impact energy (17.1 J). The optical image of impact damage behavior shows minimum damage of impactor on the composite and penetration effect found to be lower. This luffa aegyptiaca fiber reinforced epoxy composite also shows the lowest value of coefficient of friction (COF) with 0.48 and the lowest specific wear rate of 0.011 mm3/Nm. These epoxy composites made from luffa aegyptiaca fiber and CHB particles may be useful in a variety of engineering applications that can use materials for manufacture sporting goods, home furnishings, food packaging, and transportation.

In this current study, high‐toughness epoxy bio‐composites were prepared and characterized for lightweight and low‐cost technological applications using novel palmyra sprout fiber (PSF) and red matta rice husk (RHA) biosilica. The principal aim of this research was to study how the alkali‐silane treatments on the fiber and particle influence the mechanical, wear, thermal and hydrophobic behavior of epoxy composites. The PSF was alkali‐silane treated whereas the biosilica was treated only with silane. The composites were prepared via a hand layup process and characterized. According to the results, the treated PSF with 3 vol.% RHA biosilica has the maximum tensile, impact, flexural strength, and hardness. The composite with the inclusion of 5 vol.% biosilica, and the palmyra sprout fiber has the lowest specific wear rate and COF of 0.007 mm3/Nm and 0.37. Moreover, these composites possess good thermal stability with the highest initial decomposition temperature of 342°C. Similarly, the composite designation ESP3 have the lowest contact angle of 75.7°, which is within the hydrophobic limit. These composites with improved mechanical, thermal and wear properties may be useful in a variety of engineering applications that can be used for high load‐bearing capacity and biodegradability, such as sporting goods, automobiles, home furniture, food packaging, transport, and aircrafts.
