Effects of interfacial modification and Fiber Content on physical properties of sisal Fiber/polypropylene composites
Composites Part B-engineering, 2013Co-Authors: Sulawan Kaewkuk, Wimonlak Sutapun, Kasama JarukumjornAbstract:Abstract Sisal Fiber (SF)/polypropylene (PP) composites were prepared at Fiber Content of 10, 20, and 30 wt.% and their mechanical, thermal, morphological, and water absorption properties were characterized. The effects of Fiber treatment (alkalization and heat treatment) and adding a compatibilizer (maleic anhydride grafted polypropylene, MAPP) on the properties of the PP composites were comparatively studied. The Fiber treatment and adding MAPP led to an improvement of mechanical properties, cellulose decomposition temperature, and water resistance of the PP composites. SEM micrographs revealed that the interfacial modification enhanced the interfacial adhesion between the Fiber and the PP matrix. Alkalization and heat treatment provided comparable enhancement in the mechanical properties of the sisal Fiber/PP composites. Adding MAPP showed the most effective improvement of the mechanical properties of the PP composites. With increasing Fiber Content, tensile strength and modulus of the PP composites increased but impact strength and elongation at break decreased. Water absorption of PP composites also increased with Fiber Content.

Sisal Fiber/Natural Rubber Composites: Effect of Fiber Content and Interfacial Modification
Advanced Materials Research, 2011Co-Authors: Wittawat Wongsorat, Nitinat Suppakarn, Kasama JarukumjornAbstract:Sisal Fiber/natural rubber (NR) composites were prepared by the incorporation of sisal Fiber into NR at Contents of 10-30 phr. Fiber treatment (alkalization) and adding maleic anhydride grafted natural rubber (NR-g-MA) were used to improve interfacial adhesion between sisal Fiber and NR matrix. Mechanical properties, morphologies, and cure characteristics of the composites were studied. With increasing Fiber Content, modulus at 100% strain (M100), modulus at 300% strain (M300), and hardness of the composites increased whereas tensile strength and elongation at break decreased. Cure time of the composites decreased with increasing Fiber Content but scorch time was not much affected by Fiber Content. Alkali treated sisal Fiber/NR composite exhibited higher tensile properties and hardness than untreated sisal Fiber/NR composite at all Fiber Content due to the improved adhesion between Fiber and NR matrix through the mechanical interlocking mechanism. Alkalization showed no effect on scorch time and cure time of the composites. The addition of NR-g-MA into the composites increased M100, M300, tensile strength, and hardness but prolonged scorch time and cure time. NR-g-MA provided more effective improvement of the mechanical properties of the composites when compared to Fiber alkalization.

influence of Fiber Content on mechanical morphological and thermal properties of kenaf Fibers reinforced poly vinyl chloride thermoplastic polyurethane poly blend composites
Materials & Design, 2014Co-Authors: Y A Elshekeil, S M Sapuan, Mohammad Jawaid, O M AlshujaaAbstract:Kenaf (Hibiscus Cannabinus) bast Fiber reinforced poly(vinyl chloride) (PVC)/thermoplastic polyurethane (TPU) poly-blend was prepared by melt mixing method using Haake Polydrive R600 internal mixer. The composites were prepared with different Fiber Content: 20%, 30% and 40% (by weight), with the processing parameters: 140 °C, 11 min, and 40 rpm for temperature, time and speed, respectively. After mixing, the composite was compressed using compressing molding machine. Mechanical properties (i.e. tensile properties, flexural properties, impact strength) were studied. Morphological properties of tensile fracture surface were studied using Scanning electron microscope (SEM). Thermal properties of the composites were studied using Thermogravimetric Analyses (TGA). PVC/TPU/KF composites have shown lower tensile strength and strain with increase in Fiber Content. Tensile modulus showed an increasing trend with increase in Fiber Content. Impact strength decreased with increase in Fiber Content; however, high impact strength was observed even with 40% Fiber Content (20.2 kJ/m2). Mean while; the 20% and 30% Fiber Contents showed higher impact strength of 34.9, 27.9 kJ/m2; respectively. SEM showed that there is poor Fiber/matrix adhesion. Thermal degradation took place in three steps. In the first step, composites as well as the matrix had a similar stability. At the second step, matrix showed a slightly better stability than the composites. At the last step, composites showed a better stability than the matrix.

influence of Fiber Content on the mechanical and thermal properties of kenaf Fiber reinforced thermoplastic polyurethane composites
Materials & Design, 2012Co-Authors: Y A Elshekeil, S M Sapuan, Khalina Abdan, E S ZainudinAbstract:The aim of this paper is to study the influence of Fiber Content on mechanical (i.e. tensile, flexural, impact, hardness and abrasion resistance) and thermal (i.e. TGA) properties of Kenaf bast Fiber reinforced thermoplastic polyurethane (TPU) composites. The composite was prepared by melt-mixing method, followed by compression molding process. Different Fiber loadings were prepared; namely, 20%, 30%, 40%, and 50% weight percent. A 30% Fiber loading exhibited the best tensile strength, while modulus increased with increase of Fiber Content, and strain deteriorated with increase of Fiber Content. Flexural strength and modulus increased with increase of Fiber loading. Increase of Fiber loading resulted in decline in impact strength. Hardness increased by addition of 30% Fiber Content. Abrasion resistant decreased with increase of Fiber loading. Fiber loading decreased thermal stability of the composite.
