“…Prior to use, these fibers were soaked in 2% NaOH solution for 24 hours at room temperature for attaining a good mechanical interlocking and interfacial adhesion between the fiber and matrix, which result in improved mechanical properties. [34,35] Thereafter, the fibres were washed with distilled water and then oven dried for 12 h at 60 C temperature. The oven dried fibers were chopped into 8-12 mm length and used in composite fabrication.…”

“…S3/ S4. S. M. Maharana et al, [34] while studying the impact of silica nanoparticles (0, 1.5, 3%, 4.5 wt%) on fracture toughness of jute-Kevlar fiber reinforced hybrid nanocomposite concluded that fracture toughness remains highest for 3 wt% silica nanoparticles loaded composites and decreased thereafter. Fiber reinforced polymer composites generally accompanied with plenty of voids inherited due to the manufacturing errors.…”

“…An increase of 23% in tensile strength and 37% increase in flexural strength was observed with 4 wt.% silica nanoparticles added composites. Another research group, S. M. Maharana et al, [34] studied the effect of fumed silica nanoparticles and stacking sequence of jute-Kevlar on fracture toughness of manufactured hybrid nanocomposite. The mode I fracture toughness was greatly influenced by the addition of silica nanoparticles and it was determined that in a comparison of pure Kevlar stacking sequence and hybrid jute fibre and Kevlar fibre stacking sequence composites, the mode II fracture toughness was almost 37% higher for hybrid jute-Kevlar fibre nanocomposites with 3 wt% silica nanoparticles.…”

Hemp-sisal natural fiber-reinforced hybrid epoxy composites containing a varying proportion of silica nanoparticles (0, 1, 2, 3, and 4 wt%) were manufactured and subsequently evaluated for physical, mechanical, and sliding wear properties. The density of the composite was found to increase, whereas void content was found to decrease with the increase of silica nanoparticles content. The composites containing 2 wt% silica nanoparticles exhibit maximum tensile strength, impact strength, and hardness, whereas the composite with 3 wt% silica nanoparticles showed the highest flexural strength. Dry sliding wear tests of the manufactured composites were carried out on a pin-on-disc machine under different sliding speeds, distances and applied loads at room temperature. Taguchi based L 16 orthogonal array design was used to find the optimum combination of control factors resulting in higher wear resistance. The analysis reveals that the silica nanoparticles contribute the most towards wear performance with a contribution ratio of 32.61% and a combination of 2 wt% of silica nanoparticles, 10 N normal load, 1.5 m/s sliding speed and 500 m sliding distance resulted in higher wear resistance.

This research article studied the manufacturing of bi-directional kenaf fabric reinforced epoxy composites hybridized with carbon fabrics in various stacking sequences and the effect of hybridization on these composites' physical and mechanical properties. Pure and hybrid composites were fabricated utilizing the vacuum-assisted resin infusion method. The hybridization of 16 vol. % carbon fabrics increased the density of pure kenaf/epoxy composites by around 5%. The mechanical performance of kenaf/epoxy composites improved by changing the fiber volume fraction and stacking sequence of carbon fabrics in the hybrid composites. Approximately 16 vol. % carbon fiber volume fractions in hybrid composites improved the tensile, flexural, and interlaminar shear performance of kenaf/epoxy composites up to 400%, 268.8%, and 281%, respectively. The stacking sequence affected the tensile, flexural, interlaminar shear, water absorption, and fracture toughness performance. The highest tensile strength and modulus were shown by hybrid KC2 among all tested hybrid composites. Hybrid KC4 had higher flexural strength, flexural modulus, interlaminar shear strength and lower water absorption and thickness swelling. The highest fracture toughness can be achieved using the KC1 (Ft) hybrid. As a result, carbon fabrics can be used as a skin layer in various stacking sequences with kenaf fabrics in epoxy composites, depending on the targeted structural application.

“…[31][32][33][34][35] Moreover, very few literatures have been reported on the effect of moisture absorption on the interlaminar fracture behavior of hybrid composite. The delamination or interlaminar crack propagation inside an FRP depends on many factors such as weight/volume percentage of reinforcement, [36] filler weight percentage, [37] fiber orientation angle, [38] fiber-matrix interface, [39] and weave configuration. Liu and Hughes [38] reported that the stacking sequence and weaving pattern strongly influence the fracture toughness of the composite.…”

This work aims to examine the influence of moisture uptake of fumed silica reinforced Jute (J)-Kevlar (K) hybrid composite on Mode I interlaminar fracture toughness. Mode I interlaminar fracture behavior is characterized by using the double cantilever beam (DCB) test specimen. Thirteen different composites are prepared based on four stacking sequences (i.e., Jute-Jute-Jute-Jute [JJJJ], Jute-Kevlar-Kevlar-Jute [JKKJ], Kevlar-Jute-Jute-Kevlar [KJJK], and Kevlar-Kevlar-Kevlar-Kevlar [KKKK]) and four nanofiller percentages (i.e., 0%, 1.5%, 3%, and 4.5%). Mode I fracture is experimented by using DCB test specimens. Mode I fracture energy (G IC ) and Resistance curve (R-curve) is evaluated by using the modified beam theory (MBT) data reduction method at dry and wet conditions of the specimens. The interlaminar fracture surface of the composites is analyzed using an optical microscope. It is noticed that moisture ingression severely affects the fiber bridging, which is a key factor influencing the Mode I fracture resistance. The presence of fumed silica also plays a vital role by preventing the microcracks generation surrounding the fibers due to fiber swelling. The fiber swelling is caused by moisture ingression.The composite with stacking sequence JKKJ and 3% of nanofiller (JKKJ-3) is proved to be the reasonable Mode I fracture-resistant material in moist environment.
