Water Hyacinth Fiber

In this work, the effect of PE-g-MAH as compatibilizer in polyethylene/ natural rubber/ water hyacinth fibers composites were prepared and characterized in terms of tensile properties, morphology properties, swelling behavior and FTIR characteristic. Water hyacinth fibers (WHF) was used as reinforced fiber in the composites incorporated into the LDPE/NR matrices with different fiber loading. LDPE/NR/WHF composites were prepared with Z-blade mixer at 180°C with rotor speed of 50 rpm for 10 minutes. The presence of PE-g-MAH increased the tensile strength and Young’s modulus while reduced the elongation at break of LDPE/NR/WHF composites. The molar sorption of the composites decreased as the fiber loading increased. SEM morphology showed a better fiber dispersion and fiber distribution indicated PE-g-MAH improved the interfaces between water hyacinth fiber and LDPE/NR matrices. The absorption peak at 1741.52cm-1indicated ester carbonyl group in LDPE/NR/WHFPE-g-MAHcomposites.

In this work, the effect of PMMA in low density polyethylene/water hyacinth fibers composites were prepared and characterized in terms of tensile properties and FTIR characteristics. Water hyacinth fibers (WHF) were incorporated into the LDPE matrix with different fiber loading. LDPE/WHF and LDPE/WHFPMMAcomposites were prepared with Z-blade mixer at 180 °C with rotor speed of 50 rpm. The PMMA modified WHF increased the tensile strength and Young’s modulus while reduced the elongation at break of LDPE/WHFPMMAcomposites in comparison with LDPE/WHF composites. The absorption peak at 1736.28 cm-1indicated the presence of ester carbonyl group (C=O) in LDPE/WHFPMMAcomposites.

The effect of dynamic vulcanization and fiber loading on properties of low density polyethylene (LDPE)/natural rubber (NR)/water hyacinth fibers (WHF) were investigated. In this study, the vulcanized thermoplastics were obtained by in situ dynamic curing of LDPE/NR/WHF composites. The LDPE/NR/WHF composites with different fiber loading were prepared by using Brabender mixer at 180 °C with the rotor speed of 50 rpm. The results showed that dynamic vulcanized LDPE/NR/WHF composites gave a higher tensile strength, Young’s modulus, elongation at break but lower molar sorption than unvulcanized LDPE/NR/WHF composites. The SEM micrographs also displayed better fibers dispersion and the crosslink formation in dynamic vulcanized LDPE/NR/WHF composites indicated better interfacial bonding among fibers and matrix compared to unvulcanized LDPE/NR/WHF composites.

The effects of benzyl urea into RHDPE/NR/CFF composites with different fibers loading were studied. The composites were prepared using BrabenderPlasticorder at 160 °C with rotor speed of 50rpm. The composites were characterized in respect of their tensile properties and morphology. The results indicated that RHDPE/NR/CFF with benzyl urea composites show higher values of tensile strength, Youngs modulus, but lower elongation at break than RHDPE/NR/CFF composites. RHDPE/NR/CFF with benzyl urea composites gave a better interfacial adhesion between the matrix and the fiber than RHDPE/NR/CFF composites as evidence using SEM.

The compatibilizer effect of ENR-50 on the tensile properties of high density polyethylene (HDPE)/recycled acrylonitrile butadiene rubber (NBRr)/banana skin powder (BSP)/ composites has been studies. HDPE/NBRr/BSP composites were prepared by melt mixing technique using twin-screw at 180 °C for 9 minutes at rotor speed 50 rpm. The six different composites studied were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. As for compatibilized composite a fix 5 wt% of ENR-50 was evaluated. The specimens were analysed for tensile strength and elongation at break (Eb). The results showed that tensile strength and the elongation at break were decreases with the increasing of NBRr loading. However for ENR-50 compatibilized composites, higher tensile strength and elongation at break was recorded. The ENR-50 was found to be an excellent compatibilizer for HDPE/NBRr/BSP composites.

This research focused on the utilization of kapok husk (KH) as filler in low linear density polyethylene (LLDPE). The effect of filler content on tensile properties and morphology of LLDPE/KH eco-composites were investigated. The eco-composites were prepared by using Brabender Plasticiser EC Plus at temperature 160 °C and rotor speed 50 rpm. The results indicated that the tensile strength and elongation at break decreased with KH content increased. However, the modulus of elasticity increased with increasing of KH content. The morphology study of eco-composites exhibit poor interfacial adhesion between KH and LLDPE.

Wollastonite is one type of inorganic filler. The effects of wollastonite loading on tensile properties of wollastonite (WS) filled high density polyethylene (HDPE)/Natural Rubber (NR) composites was studied. The HDPE/NR/WS composites were prepared by using Brabender EC Plus at a temperature of 180 °C with rotor speed of 50 rpm for 10 min. It was found that the increasing of wollastonite loading had decreased the tensile strength and elongation at break, whereas the Young’s modulus of the HDPE/NR/WS composites had increased with the increasing of wollastonite loading.

This research studied the influence of treated water hyacinth fibers with chemical substances and the orientation of water hyacinth (WH) fiber reinforced bio-based epoxy composite on mechanical properties. The specimens with direction at 90˚, 45˚ and 0˚ of WH fiber and different treatment substance were investigated. Sodium hydroxide (NaOH) and (3-Aminopropyl) triethoxysilane were used for the chemical treatment of fiber, which can improve the mechanical properties of the composite. The result shows that the tensile modulus of 1% silane treated WH fiber is higher than neat epoxy around 15%. The orientation of the fiber affects directly on the tensile strength. The addition of the WH fibers improves impact properties in all conditions compared to original epoxy.
