“…Another approach widely used to properly tailor the mechanical and physical properties of natural fiber reinforced composites is the hybridization of these natural fibers with stronger and more aging resistant synthetic fibers such as glass [22,23,24,25] carbon [26,27,28,29,30,31,32] and Kevlar [33,34] or mineral fibers, such as basalt [35,36,37,38,39,40]. On the other hand, few literature references are available until now on hybrid composites reinforced with different natural fibers [41,42,43].…”

The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed to evidence that the sodium bicarbonate treatment leads to noticeable improvement of the mechanical performances of flax reinforced composites, whereas jute composites experience a slight decrease of their mechanical properties. Overall, the hybridization allows to achieve intermediate mechanical properties among those of monolithic composites. Furthermore, the coupled action of hybridization and surface treatment does not lead to a beneficial and reliable effect on the mechanical response of the resulting composites.

“…Tensile Test. The tensile test determines the maximum load (tensile strength) that a material can withstand without breaking [29]. Five samples of each type (1 × 1, 3 × 3, and 5 × 5) were used in the tensile testing, yielding 15 readings.…”

Hybrid composites made of natural and synthetic fibers are stronger, lighter, cheaper, biodegradable, and greener than conventional metals, and they are replacing conventional metals. The primary objective of the study was to examine the mechanical properties of interwoven hybrid composite laminates. Kevlar and glass fiber are used as reinforcement for this work. The fibers are woven together using various weaving techniques. 1 × 1, 3 × 3, and 5 × 5 weaving patterns are considered to explore the properties of the laminates. The composites are woven using a conventional handloom method. As a matrix, LY556 resin and HY951 hardener are combined at a ratio of 10 : 1. The composites are cured using compression molding. The cured composites are assessed for their tensile strength, flexural strength, compressive strength, interlaminar shear strength, impact strength, and fracture toughness. The highest tensile, compressive, and flexural strength were found in the 1 × 1 pattern, shear strength and fracture toughness were found in the 5 × 5 pattern, which finds applications in aerospace and defense sectors, and 3 × 3 dominated in impact strength; as a result, it can be used in bulletproof applications. At last, a scanning electron microscope (SEM) was used to visualize the matrix-reinforcement bonding. The microscopic images show the ripped-out fibers because of the tensile test. The shards in SEM are evident that impact force breaks the matrix elements in a brittle manner.

“…Among the tremendous types and forms of fibers, aramid fibers (Kevlar) are considered one of the primary contributors to the stiffness, strength and other critical properties of the polymer composite. Because Kevlar fibers have 5-10% higher mechanical properties such as tensile strenght, impact energy and flexural strength than other synthetic fibers, it had been utilized in advanced technology like armor, ballistic, helicopter blades, and pneumatic reinforcement [5][6][7][8][9].…”

This research was aimed to perform a symmetric investigation regarding the influence of two types of nanoparticles, on some mechanical and morphological behaviors of the Kevlar/epoxy nanocomposites. Composites were prepared by dispersing nanoparticles of nano ZnO and TiO2 at loading of 1, 2 and 4 wt.% of each in (Kevlar/epoxy) composite using high speed mechanical mixer followed by sonication, then injecting them inside the cavity of a two plates glass mold. After curing they were characterized by tensile tests, flexural test, creep test and SEM. The results showed that the maximum increase of mean stress (41%) and the maximum flexural strength was obtained for system containing 4 wt.% of both nano ZnO and TiO2 particles, i.e., EKZ4 and EKT4 . SEM images for processed specimens were taken to observe the analogy distribution of both nanoparticles through the fiber/epoxy system. The improvement in the mechanical properties of nanocomposite EKT2 (2% TiO2)and EKZ2 (2% ZnO) attributed by the homogeneity of the nanoparticles distribution inside the epoxy which appear in SEM images. Also, the semispherical shape of nanoparticles led to uniform distribution of the nano particles inside Epoxy-keflar resin.
