TL;DR: In this article, a high strength electrical insulating material was developed using fibrillated sisal and epoxy resins, where coarse sisal fibers were fibrilled into fibrils using mechanical disintegration.
Abstract: Environment friendly high strength electrical insulating material was developed using fibrillated sisal and epoxy resin. Coarse sisal fibers were fibrillated into fibrils using mechanical disintegration. Fibrillated fibers provided a high strength, renewable, light weight dielectric variant reinforcement to epoxy resin. Different weight fractions (10–35%) of Agave sisalana fibrils were thoroughly mixed with epoxy resin system to develop composites. Chemical treatment was employed to improve the surface as well as chemical composition of sisal fibril to enhance mechanical strength and electrical insulating properties of composite. Chemical treatment of fibrils improved the tensile strength from 47.4 to 51.99 MPa at 35 wt% loading of sisal fibril in epoxy composite. A few important predictive models namely rule of mixture, Halpin–Tsai, Nielson Chen and Manera model were compared with the experimental values obtained in this present study. Nielson Chan model predicted the experimental data most accurately with an average relative error of 15.82%. Similarly the dissipation factor touched a level of 0.097, thereby indicating good insulation properties of composite. The tests were conducted at lower frequency range to higher frequency range 1–10 kHz and the composite material exhibited stability at high frequency range as compared to low frequency range. POLYM.

TL;DR: In this paper, sisal fiber was hybridized with corn fiber to reinforce polylactide polysilicon composites, and sisal fibre was used as a reinforcement for polylactic acid.
Abstract: The relatively poor mechanical properties of corn fibre (CF) and its green composites have hindered its applications. In this work, sisal fibre (SF) was hybridised with CF to reinforce polylactide ...

TL;DR: In this paper, the polyaniline modified sisal fibers were characterized by thermal, spectroscopic and microscopic techniques and it was shown that the fiber was coated with polyanILine through in situ oxidative polymerization and the latter had a smoothing effect on the surface as compared to uncoated sisal fiber.
Abstract: Sisal (Agave sisalana) fiber was extracted by manual process. These fibers were subjected to surface coating with conducting polyaniline, through in situ oxidative polymerization. The polyaniline modified sisal fibers were characterized by thermal, spectroscopic and microscopic techniques. It was shown that the fiber was coated with polyaniline through in situ oxidative polymerization and the latter had a smoothing effect on the surface as compared to uncoated sisal fiber. Besides, it was confirmed that polyaniline was deposited in conductive form of emeraldine salt. This in turn verified the introduction of active functionalities to the system, which is helpful to tune up surface chemistry of polyaniline for water treatment applications.

TL;DR: In this paper, the ratio of sisal fiber to magnesium hydroxide (Mg(OH)2) was used as a flame retardant in sisal/polypropylene composites.
Abstract: Due to environmental reasons and their acceptable mechanical properties, natural fiber based polymer composites have been increasingly used in various applications, e.g. housing materials, automotive parts. However, their low thermal resistance and fire behavior limit the use of these materials. In this work, magnesium hydroxide (Mg(OH)2), as a flame retardant, was incorporated into sisal/polypropylene composites. Ratio of sisal fiber to Mg(OH)2 in each composite sample was varied. Maleic anhydride grafted polypropylene (MAPP) was also used to improve the interface of polypropylene and fillers. Flammability and thermal behavior of the composites were examined using a horizontal burning test and thermo gravimetric analyzer, respectively. Morphology and mechanical properties of the composites were also investigated.
