“…As has been reported by Joffe and Anderson [14], it could be attributed to the increases of the stiffness of the composite by increases of fiber content to reinforced thermosetting plastics. It was clear that, for the composite sample with 60% kenaf fiber content, higher values of impact strength record compared to other samples.…”

“…It is clearly seen that the composite material with 60% kenaf fibers content have the greatest impact toughness value of 0.085 J/mm 2 . As the research study has been reported, both fiber content and properties of the polymer are accountable for deciding the impact toughness [13,14]. This implies that both effect of interlaminar delamination and interfacial adhesion between fiber and matrix highly decide impact properties [15].…”

In this study, the impact properties of kenaf fibre reinforced hybrid fiberglass/Kevlar polymeric composite was investigated. In this study, a new fiber arrangement based on kenaf bast fiber as reinforcement to the hybrid fiberglass/Kevlar fiber and polyester as matrix used to fabricate the hybrid polymeric composite. Five different types of samples with different of kenaf fiber content based on volume fraction (0, 15, 45, 60 and 75%) to hybrid fiberglass/Kevlar polymer composites were manufactured. 0% of kenaf fiber has been used as control sample. The results showed that hybridization has improved the impact properties. These results were further supported through SEM micrograph of the manufacturing defects of the polymer composite. Based on literature work, manufacturing defects that occurs in composite system reduced the mechanical properties of the material. Therefore, in this research the correlation of impact behaviors and manufacturing defects of kenaf fiber reinforced hybrid fiberglass/Kevlar polymeric composite has been successfully done. As conclusion, the highest manufacturing defects determined in the composites during the fabrication significantly lowest the results of impact behavior.

“…This is attributed to the fact that the increase of fiber content above 40% causes lack of energy absorbance. It could be attributed to the increase of the stiffness of the composite by increase of fiber content to reinforced thermoplastics, as reported by Joffe and Andersons [33]. Generally, it can be seen that the impact energy strongly depends on the percentage of the fiber content, especially when combining natural fibers with thermoplastics [34,35], as shown in Figure 9.…”

This work addresses the results of experimental investigation carried out on mechanical and morphological properties of plain woven kenaf fiber reinforced PVB film which was prepared by hot press technique. The composites were prepared with various fiber contents: 0%, 10%, 20%, 30%, 40%, 50%, and 60% (by weight), with the processing parameters 165°C, 20 min, and at a pressure of 8 MPa applied on the material. Tensile, flexural, and Charpy impact properties were studied as well as morphological properties of impact fracture surface. With the increase in kenaf fibers content up to 40%, the PVB composites have shown lower tensile and flexural strength accompanied with reduction in the ultimate strain of the composite. The results showed that impact properties were affected in markedly different ways by using various kenaf contents and decrease with the increase in kenaf fiber content up to 40%; however, high impact strength was observed even with 40% kenaf fiber content. Furthermore, scanning electron microscopy for impact samples was utilised to demonstrate the different failures in the fracture surfaces for various kenaf fibers contents.

“…This is directly comparable (and even better) than typical values of Young's modulus reported for short fiber composites with a thermoplastic matrix. [18][19][20][21][22][23][24] Figure 6 shows the measured Young's modulus of the composites as a function of V f . Results are only shown for composites where the volumetric composition has been measured (Table 2).…”

This study is presented to predict the Young’s modulus of injection-molded short cellulosic fiber/plasticized starch acetate composites with variable fiber and plasticizer content. A modified rule of mixtures model is applied where the effect of porosity is included, and where the fiber weight fraction is used as the basic independent variable. The values of the input model parameters are derived from experimental studies of the configuration of the composites (volumetric composition, dimensions, and orientation of fibers), as well as the properties of the constituent fiber and matrix phases (density and Young’s modulus). The measured Young’s modulus of the composites varies in the range 1.1—8.3 GPa, and this is well predicted by the model calculations. A property diagram is presented to be used for the tailor-making of composites with Young’s modulus in the range 0.2—10 GPa.
