“…Indirectly, vacuum infusion process is reported to give more advantages compared to hand lay-up process for woven kenaf composites. However, unidirectional type fibre tends to exhibit outstanding mechanical properties compared to woven kenaf composites as shown in Table 1 [18,23,24]. The volume of fibre in each area of kenaf may affect and influence the mechanical properties of kenaf composites [24].…”

“…Several researches on kenaf composites have already been conducted such as analysis studies on the effect of chemical treated on kenaf [17,18], fibre fraction [8,19], woven orientation [17,20,21], hybrid effect [13], and resin application [7,10,22,23]. A few elements are highlighted in the study that influence the mechanical properties of natural fibre such as the volume fraction, the interfacial adhesion of the fibre with the matrix, and orientation of the fibre and length of the fibre [18,24]. These reports are summarized in Table 1.…”

The synthetic fibres have created some issues including risk of inhalation during fabrication process, renewability, biodegradability, and recyclability in composites industry. The usage of biocomposites as a replacement to synthetic fibres is beginning to be widespread. However, it is noted that lesser attention has been devoted to evaluating the mechanical properties of woven kenaf composites at various woven and stacked layer orientation. Thus, the research objective is to identify the effect of woven and stacked layer orientation on tensile and flexural properties of kenaf composites. Two types of fibre orientation are employed; type A contains a higher yarn density and type B contains a low yarn density. The tensile and flexural tests are conducted to analyze the mechanical properties of woven kenaf fibre composites and compare them to random chopped kenaf composites. The fracture interface between fibre and matrix epoxy is further investigated via scanning electron microscope. Type A kenaf improved up to 199% and 177% as compared to random chopped kenaf for flexural strength and tensile strength, respectively. Scanning electron microscopy analysis shows that resin matrix is properly induced into kenaf fibre gap hence giving additional strength to woven kenaf as compared to random chopped kenaf.

“…Natural fibers are potential replacement of synthetic fibers due to their biodegradability, renewability, and cheaper price. However, in terms of mechanical properties, synthetic fibers demonstrated higher mechanical properties, causing limited application for natural fiber-reinforced composites [1][2][3][4][5][6][7][8][9][10][11][12][13]. Kenaf is one of the natural fibers that shows reasonably good mechanical properties with different types of resin [14].…”

In this experiment, thermoset cardanol resin was reinforced with short kenaf bast fibers to produce 100% green composites. Different fiber loadings based on weight ratios (0%, 30%, 40%, 50%, and 60%) were fabricated by the hand layup method followed by compression molding. e results indicated that 50UTK (untreated kenaf fibers) displays the highest mechanical properties (91.9% and 43.4% increment for tensile strength and impact strength, respectively) compared with the brittle cardanol polymer and other combinations of composite. is indicates a great load transfer mechanism by kenaf fiber reinforcement due to good fiber/matrix interface shown in scanning electron microscope (SEM) analyses. On the contrary, short kenaf fiber insertion creates a stress concentration spot at the fiber's end causing slightly lower flexural properties. Besides, high processing temperature has caused damage to the fibers and made further reduction of flexural strength. erefore, a better load transfer mechanism has been compensated by negative influences of kenaf fiber insertion. In conclusion, 50 wt% of kenaf fiber insertion is found to be the optimum loading for cardanol matrix.

In recent years, woven fabrics of natural fibers have been used to develop toughened epoxy composites with higher tensile and flexural properties . Among all the fibers, sisal fiber is widely used (Agave sisalana) as fillers for thermosets because of its abundant availability, less density, economical processing, low cost, higher specific strength, better impregnation, and good interfacial interaction with thermoset resins .…”

Sisal fiber reinforced biocomposites are developed using both unmodified petrol based epoxy and bioresin modified epoxy as base matrix. Two bioresins, epoxidized soybean oil and epoxy methyl soyate (EMS) are used to modify the epoxy matrix for effective toughening and subsequently two layers of sisal fiber mat are incorporated to improve the mechanical and thermomechanical properties. Higher strength and modulus of the EMS modified epoxy composites reveals good interfacial bonding of matrix with the fibers. Fracture toughness parameters K IC and G IC are determined and found to be enhanced significantly. Notched impact strength is found to be higher for unmodified epoxy composite, whereas elongation at break is found to be much higher for modified epoxy blend. Dynamic mechanical analysis shows an improvement in the storage modulus for bioresin toughened composites on the account stiffness imparted by fibers. Loss modulus is found to be higher for EMS modified epoxy composite because of strong fibermatrix interfacial bonding. Loss tangent curves show a strong influence of bioresin on damping behavior of epoxy composite. Strong fiber-matrix interface is found in modified epoxy composite by scanning electron microscopic analysis. V C 2015 Wiley Periodicals, Inc. J.Appl. Polym. Sci. 2015, 132, 42699.
