“…It is worth noting that using thermoset resin such as epoxy and polyester is strongly recommended as the matrix in developing natural fiber composites for structural applications [30]. Research into the feasibility of reinforcing epoxy or polyester with natural fibers has been reported in several literature [31][32][33][34]. A comprehensive theoretical framework for the new sandwich structure panel developed in this research under flexural loading was thoroughly discussed [35], while the statistical analysis of the flexural test was reported earlier [36].…”

Polymeric composites reinforced with natural fibers have raised more attention as the alternative building materials. In this work, natural fiber composites prepared from jute and hemp fiber were proposed for the intermediate layer of a hybrid sandwich panel. This paper presented the flexural behavior of the newly developed hybrid sandwich panel which included the comparison of the ultimate load, load-deflection behavior, load-strain behavior and failure modes. The study was designed as a single factor experiment where the performance of hybrid sandwich panels containing jute fiber composite (JFC) and hemp fiber composite (HFC) as the intermediate layer was compared to the control (CTR) which was a conventional sandwich panel without an intermediate layer. A static flexural test under a four-point bending load scheme was performed in accordance with the ASTM C 393-00 standard. Aluminium sheet was used as the skins, while expanded polystyrene (EPS) was employed for the core. The testing was performed using a 100 kN servohydraulic machine with a loading rate of 5 mm/min. The applied load, displacement and strains were obtained using data logger. The results demonstrated that the hybrid sandwich panel exhibited a more superior performance than the conventional sandwich panels. The intermediate layer contributed significantly to enhancing the load carrying capacity of the hybrid sandwich panel. The load carrying capacity of hybrid panel with the JFC intermediate layer was 29.60% higher than the conventional sandwich panel, and correspondingly 93.46% higher for the sandwich panel with the HFC intermediate layer.The hybrid sandwich panels also developed a much larger area under the load-deflection curve, indicating greater toughness. The introduction of intermediate layer helped the hybrid sandwich panels to sustain a larger strain prior to reach their ultimate loads, resulting in a higher deformation capability. Indentation and core shear were observed as the failure mode of the conventional sandwich panel. Meanwhile, core shear and delamination were identified as the failure mode of the hybrid sandwich panel.

“…Recently, natural plant fibers have been used in scientific researches as potential alternatives to glass fibers (GF) in fiber-reinforced plastics (FRP). Relative to glass fibers, these lignocelluloses fibers have lower densities, cost relatively lower, consume lesser energies during production, pose no abrasion to machines and have no health risk when inhaled [4][5][6][7][8][9][10].…”

A comparison of tensile properties of polyester composites reinforced with pineapple leaf fiber and pineapple peduncle fiber Abstract. Pineapple fiber which is rich in cellulose, relatively inexpensive, and abundantly available has the potential for polymer reinforcement. This research presents a study of the tensile properties of pineapple leaf fiber and pineapple peduncle fiber reinforced polyester composites. Composites were fabricated using leaf fiber and peduncle fiber with varying fiber length and fiber loading. Both fibers were mixed with polyester composites the various fiber volume fractions of 4, 8 and 12% and with three different fiber lengths of 10, 20 and 30 mm. The composites panels were fabricated using hand lay-out technique. The tensile test was carried out in accordance to ASTM D638. The result showed that pineapple peduncle fiber with 4% fiber volume fraction and fiber length of 30 mm give highest tensile properties. From the overall results, pineapple peduncle fiber shown the higher tensile properties compared to pineapple leaf fiber. It is found that by increasing the fiber volume fraction the tensile properties has significantly decreased but by increasing the fiber length, the tensile properties will be increased proportionally. Minitab software is used to perform the two-way ANOVA analysis to measure the significant. From the analysis done, there is a significant effect of fiber volume fraction and fiber length on the tensile properties.

“…FLO has a good UV stability and has hence been promoted for the use in lithographic printing. In this light, natural fibres are commonly selected as composite reinforcement to enhance performance of materials [8][9][10][11][12][13][14][15][16][17]. Solving environmental issues and better tool life are the main reasons being selected [18,19].…”

This paper presents a study of the mechanical properties of Kenaf fibre (KF) reinforced floreon (FLO)/ magnesium hydroxide (MH) bio-composites. The mixing of all materials was done by using a 21 mm lab twin screw extruder followed by hot pressing. The composite sheet was then cut into specimens for testing purposes. The scanning electron microscopy (SEM) was used to study the cross-section of the interface. In this regard, insufficient resin for fibre wetting, hydrolytic degradation on the biopolymer and poor interfacial bonding were attributed to the low strength profile. Yet, further addition of KF increased the tensile strength and flexural to 18.91 MPa and 73.09MPa, respectively. Nevertheless, inserting KF and MH filler were found to have a positive outcome on the flexural modulus by especially 10KF5MH and 10KF10MH for 3.02GPa and 3.17GPa, respectively. Insertion of KF and MH showed the deterioration of impact strength. However, addition of KF increased the impact strength to 16.82 J/m 2 . FLO is a hydrophobic biopolymer, and showed only 0.49% of the total water absorption in 14 days. Meanwhile, for the first 24 hours, the rates of water absorption were very high for all biocomposites. Hence, it is worth mentioning that the high contents of KF in bio-composites were found to have higher saturation period and higher total amount of water absorption while the MH caused shorter saturation period but lower total amount of water absorption. However, incompatibility of the interface bonding had increased the water absorption of KF/FLO/MH composites. 5KF5MH and 10KF5MH recorded water absorption at 10.65% and 13.33%. On the other hand, 10KF10MH was saturated at day 6 with 6.59 % of water absorption. Although 10KF5MH specimen did not have the best performance in mechanical properties, higher flame retardancy shall provide KF reinforced FLO composite with MH filler for more applications in the advanced sector, especially a hazardous environment.
