TL;DR: In this paper, a method for producing fruit leaf fertilizer by utilizing sisal hemp waste water is described, in which the following raw materials are adopted in parts by weight: 85-90 parts of fresh sisal waste water, 0.5-1.0 part of microelements, 5-10 parts of organic acid, 2-4 parts of molasses and 0.1-0.5 part of a surfactant.
Abstract: The invention discloses a method for producing fruit leaf fertilizer by utilizing sisal hemp waste water. The method for producing the fruit leaf fertilizer by utilizing the sisal hemp waste water is characterized in that the following raw materials are adopted in parts by weight: 85-90 parts of fresh sisal hemp waste water, 0.5-1.0 part of microelements, 5-10 parts of organic acid, 2-4 parts of molasses and 0.1-0.5 part of a surfactant. The fruit leaf fertilizer is formed through fermentation and produced by utilizing waste water after sisal hemp is processed as a main raw material, so that waste materials are changed into things of value, the environmental pollution problem is also solved, and production cost is low; reasonable microelement nutrients are added, microelements can be quickly supplemented for fruits, expansion of fruits is promoted, single fruit weight is increased, yield per mu of the fruits is increased by about 10-20% on the average, and the yield increasing effect is obvious and economic benefit is obvious compared with those of a conventional inorganic fertilizer.

TL;DR: In this article, a comparison between single and multilayered sisal fiber reinforced composites were assessed in terms of tensile, flexural and impact strength, and it was found that the multi-layer sisal fibre microwave processed composite has superior properties than single layered reinforced composite.
Abstract: The present investigation is based on fabrication of sisal reinforced high density poly ethylene (HDPE) composites using a novel manufacturing route of microwave processing. Microwave processing was carried out in a multimode applicator at 2.45 GHz with single and multi-layered sisal fibre reinforcement. The comparison between single and multilayered sisal fibre reinforced composites were assessed in terms of tensile, flexural and impact strength. It was found that the multi-layered sisal fibre microwave processed composite has superior properties than single layered reinforced composite. The fractography of tensile fractured surfaces was assessed using electron microscopy. The microwave processed HDPE/sisal composites can be used as a dashboard material of an automobile.

TL;DR: In this article, the authors evaluated the effect of the shape of the sisal fibers on the impact property of composite materials but no obvious influence on the density and hardness of the composite materials.
Abstract: In this paper, we aim to evaluate the tribological, mechanical, and morphological performance of resin-based friction composites reinforced by sisal fibers with different shapes, namely helical, undulated, and straight shapes. The experimental results show that the shape of the sisal fibers exerts a significant effect on the impact property of the composite materials but no obvious influence on the density and hardness. The friction composite containing the helical-shaped sisal fibers exhibits the best overall tribological behaviors, with a relatively low fade (9.26%), high recovery (98.65%), and good wear resistance (2.061 × 10−7 cm3∙N−1∙m−1) compared with the other two composites containing undulated-shaped fibers and straight-shaped fibers. The impact fracture surfaces and worn surfaces of the composite materials were inspected by scanning electron microscopy, and we demonstrate that adding helical-shaped sisal fibers into the polymer composites provides an enhanced fiber–matrix interface adhesion condition and reduces the extent of fiber debonding and pullout, effectively facilitating the presence of more secondary plateaus on the friction surface, which are responsible for the enhanced tribological and mechanical properties. The outcome of this study reveals that sisal fibers with a helical shape could be a promising candidate as a reinforcement material for resin-based brake friction composite applications.

TL;DR: In this paper, heat treatred sisal fibers were performed by heating the fibers in an oven at 150, 170, and 200°C under an atmospheric pressure and a presence of air.
Abstract: Sisal fiber reinforced polypropylene composites were prepared using an internal mixer. Heat treatred sisal fibers were performed by heating the fibers in an oven at 150, 170, and 200°C under an atmospheric pressure and a presence of air. The composites prepared at a fiber content of 20 wt% were molded by an injection molding machine for mechanical tests including tensile and impact properties. Morphologies of the composites were examined using a scanning electron microscope (SEM). Viscosity at various shear rate of the composites were also investigated. Tensile strength and impact strength of heat treated sisal fiber/polypropylene composites were slightly higher than that of the untreated sisal fiber/polypropylene composite. However, no remakable effect of treatment temperatures on the mechanical and rheological properties of the composites was observed. SEM micrographs revealed that the heat treatment improved adhsion between the fiber and PP matrix.
