Hydrothermal treatment of sisal fiber for composite preparation

Abstract: The influence of hydrothermal carbonization of sisal fibers on the mechanical properties of composites based on recycled polypropylene matrices was investigated in this paper. The fibers were chara...

Investigating the influence of alkalization on the mechanical and water absorption properties of coconut and sponge fibers reinforced polypropylene composites

Abstract: Natural fibers are products made from renewable agricultural and forestry feedstock, which can include wood, grasses, and crops, as well as wastes and residues. There are two primary ways these fibers are used: to create polymers or as reinforcement and filler. Thermoplastic polymer may be reinforced or filled using natural fibers such as coir, sponge, hemp, flax, or sisal. This paper focused on the influence of alkalization (NaOH treatment) on the mechanical and water absorption properties of selected natural fibers (coconut and sponge fibers) reinforced polypropylene composites. In this study, coconut and sponge fiber were extracted from its husk by soaking them in water and was dried before it was cut into 10mm length. Those fibers were chemically treated with sodium hydroxide (NaOH) in a shaking water bath before it was used as reinforcement in polypropylene composite. The reinforced polypropylene composite was produced by dispersing the coconut fibers randomly in the polypropylene before it was fabricated in a compression molding machine where the composite was produced. The fiber content used

Preparation method of sisal hemp cellulose nanowhisker reinforced polylactic acid/lactic acid-hydroxyl glycolic acid copolymer bio-composite

Abstract: The invention discloses a preparation method of a sisal hemp cellulose nanowhisker reinforced polylactic acid/lactic acid-hydroxyl glycolic acid copolymer bio-composite.According to the method, polylactic acid oligomer is adopted for grafting of sisal hemp cellulose nanowhiskers, a sisal hemp cellulose nanowhisker reinforced polylactic acid material is prepared through good compatibility and interface bonding effects of the grafted sisal hemp cellulose nanowhiskers and polylactic acid, and then the sisal hemp cellulose nanowhisker reinforced polylactic acid/lactic acid-hydroxyl glycolic acid copolymer bio-composite with good phase interface bonding force and stability and excellent mechanical performance, degradation performance and bio-compatibility is prepared through a solution mixing method.The method is simple in preparation process, and the prepared sisal hemp cellulose nanowhisker reinforced polylactic acid/lactic acid-hydroxyl glycolic acid copolymer bio-composite has good phase interface bonding force and stability and excellent mechanical performance and bio-compatibility.

Experiments on Mulching Sisal with Black Polythene in Tanganyika

Abstract: Experiments in bulbil nurseries and field sisal were carried out in N.E. Tanganyika, 5°S, 39°E, 200 m. above sea level, at a mean annual rainfall of 1160 mm., on deep red loam. The discussion covers the establishment of sisal through a polythene mulch, the control of weed growth, the persistence of polythene of different thicknesses and from different sources, and some effects on growth of the sisal and on soil properties. A mulch of black polythene improved the growth of bulbil nurseries by 30 per cent or more, due to conservation of soil moisture and elimination of weed competition and disturbance associated with the removal of weeds by hoeing. For nurseries 150-gauge material was preferred, but there were important differences in the persistence of material purchased from two sources. Where black polythene is used in a nursery the density can be increased from 80,000 to 110,000 plants per hectare, to help offset the high cost of the material. A mulch of 250-g. black polythene controlled weeds in field sisal but did not improve growth.

Termite Resistant Properties of Sisal Fiberboards.

Abstract: A study was carried out to test sisal (Agave sisalana Perrine) fiberboards properties as building materials against Asian subterranean termite, Coptotermes gestroi (Wasmann). Evaluation was in the laboratory according to the JWPA Standard-TW-S.1-1992. To improve mechanical properties of fiberboards made from sisal fibers, the boards were overlaid by rubber veneer, betung bamboo matting or formica. Result showed that the formica-overlaid sisal fiberboards performed better than other overlaid fiberboards against C. gestroi.
