TL;DR: In this article , the authors explored and compared the mechanical properties of Sisal and banana fiber reinforced epoxy hybrid composites, and found that the mixture of sisal and fiber epoxy composites around 22% increased mechanical properties and decreased moisture absorption properties.

TL;DR: Sisal fiber bundles were used as reinforcements to cashew nut shell liquid (CNSL) resin for the manufacture of unidirectional fiber composites yielding composites with fibre volume fractions ranging from 0.7 to 0.8.
Abstract: Sisal fibre bundles were used as reinforcements to cashew nut shell liquid (CNSL) resin for the manufacture of unidirectional fibre composites yielding composites with fibre volume fractions ranging from 0.7 to 0.8. To improve the adhesion between hydrophilic sisal fibres and hydrophobic CN5L-formaldehydes resin matrix, sisal fibres were treated with caustic soda having concentrations ranging from 0.02 M to 0.08 M. The composite panels were tested in tension giving tensile strength and Young's modulus ranging from 104 MPa to 172 MPa and 24.54 to 33.44 MPa respectively. The specific tensile properties of sisal-CNSL composites were comparable to those where synthetic fibre such as glass fibres is used as reinforcement to thermosetting polymers such as epoxy. The use of plant fibres as reinforcement to plant based resin may be considered as a step forwards in the quest to minimize the use of fossil-fuel based resources which are energy intensive.

TL;DR: In this article, Sisal-glass fibers are taken in the weight ratio of 1:1 in order to suspend on epoxy resin with different fiber lengths such as 1, 2, and 3 cm.
Abstract: Mechanical properties viz. tensile, flexural and compression properties are studied to assess the influence of fiber length. Room temperature cured epoxy was impregnated with sisal/glass in order to synthesis hybrid composites. Sisal-glass fibers are taken in the weight ratio of 1:1 in order to suspend on epoxy resin with different fiber lengths such as 1, 2, and 3 cm. The variations of aforementioned properties on hybrid composites with different fiber lengths have been studied. Thermal properties such as TGA and DSC are studied to investigate the influence of change in fibre length on treated and untreated hybrid composites. Significant improvement in tensile, flexural, and compressive strengths of the sisal/glass hybrid composites has been observed by the alkali treatments. In TGA investigation, 3°C rise in decomposition temperature, 4°C rise for glass transition temperature in DSC analysis. © 2011 Universal Research Publications. All rights reserved

TL;DR: In this paper, a preparation method of sisal hemp-shaped CuO-ZnO composite oxide, which belongs to the technical field of inorganic functional material preparation technology and high-energy solid propellants is presented.
Abstract: The invention discloses a preparation method of sisal hemp-shaped CuO-ZnO composite oxide, and belongs to the technical field of inorganic functional material preparation technology and high-energy solid propellants. The preparation method comprises the following steps of: adding an amine chelating agent into a mixed solution of soluble copper salt and zinc salt at first to form a chelate solution; fully chelating metal ions and the chelating agent by stirring; adding an alkali metal hydroxide solution into a reaction system; controlling reaction temperature to obtain a composite oxide precipitate; and filtering, washing and drying to obtain CuO-ZnO composite oxide having a sisal hemp structure. The preparation method has the advantages that the CuO-ZnO composite oxide for ammonium persulfate (AP) catalysis is prepared; the CuO-ZnO composite oxide prepared by using the provided method has a novel structure and is sisal hemp-shaped; the high-temperature decomposition temperature is reduced to 120 DEG C, and the oxide is high in performance; and the method provided by the invention is simple in reaction process, mild in conditions, short in procedures and suitable for industrial production.
