TL;DR: The use of synthetic fibers such as glass, aramid, and carbon fiber as reinforcement for composite materials is driven by their better strength and better stiffness as discussed by the authors , however, synthetic fibers have serious drawbacks in terms of their recyclability, biodegradability, energy consumption, and implying health hazards.
Abstract: The use of synthetic fibers such as glass, aramid, and carbon fiber as reinforcement for composite materials is driven by their better strength and better stiffness. However, synthetic fibers have serious drawbacks in terms of their recyclability, biodegradability, energy consumption, and implying health hazards. The strive for more sustainable options has shifted the focus from synthetic fibers to recyclable and biodegradable lignocellulosic fibers like date palm, banana, sisal, areca, bamboo. However, shortcomings like lower tensile strength, poor interfacial adhesion, poor resistance to water absorption make them a less attractive option. It is expected that chemical pre-treatment can remove the cementing materials like lignin, hemicellulose sticking around the fibers and subsequently enhance their tensile strength. In the present study, rattan fibers were subjected to alkaline and acrylic acid treatment. Untreated fibers were used as control. Acrylic acid-treated fibers were found to improve tensile strength of lignocellulosic fibers by 26% as compared to the control. The results indicate that alkaline and acrylic pre-treatments could improve compatibility between the polar hydrophilic fibers and the non-polar hydrophobic matrix material and increase wetting of the fibers in the matrix.

TL;DR: Sisal 3.2 features a multidimensional array support, new abstractions like parametric types and generalized procedures, more flexible user-defined reductions, an improved interoperability with other programming languages and a specification of several optimizing source text annotations.
Abstract: This paper contains a short introduction of Sisal language and an overview of features introduced by Sisal 3.2 version compared to Sisal 3.1 version. Sisal 3.2 features a multidimensional array support, new abstractions like parametric types and generalized procedures, more flexible user-defined reductions, an improved interoperability with other programming languages and a specification of several optimizing source text annotations. Sisal 3.x version is used as an input language of a system of functional programming (SFP).

TL;DR: In this paper, a geometrical model was used to estimate the elastic modulus and moisture absorption capability of sisal fibres, which was found that the lumen ratio is a significant factor in determining the mechanical properties of the natural fibre.
Abstract: Microstructures of sisal fibres were revealed optically. Statistics on dimensional parameters for sisal fibres were used to establish a geometrical model in order to estimate the elastic modulus and moisture absorption capability of sisal fibres. The single fibre tensile test was conducted on the sisal. The predicted longitudinal modulus and water absorption was in good agreement with experimental results. It was found that the lumen ratio is a significant factor in determine the mechanical properties of the natural fibre.

TL;DR: In this article, the authors focused on hybridization of short mercerized sisal and glass fiber filled with nano silica and marble dust particles, by injection molding process with polypropylene matrix and found that marble dust added composite gave the better result than SiO2 added composite.
Abstract: The synthetic fibres are having high stiffness and strength still high manufacturing cost with environmental issues limited the use of synthetic fibres. This encourages towards thinking of intense research of natural fibres having similar property as synthetic fibres. To obtain the better mechanical and thermal property, hybridization of fibres is mostly preferred and that leads to minimize the use of synthetic fibres. As natural fibres are strong and having more ductile property, though moisture absorption is the primary limitation. So fibres is subjected to various treatments such as physical, thermal, chemical and laser treatments etc., to improve the surface characteristics with better interfacial bonding. Nano particle addition also helps in improving the performance of composites and develops cross linking in bonding of matrix and fibre. This research work mostly focuses on hybridization of short mercerized sisal and glass fibre filled with nano silica and marble dust particles, by injection moulding process with polypropylene matrix. It is noticed that among the addition of different fillers, marble dust added composite gave the better result than SiO2 added composite. Incorporation of SiO2 particles as filler material improves the flexural strength and thermal property of the composite.
