TL;DR: In this article, thermal and mechanical characterization of woven sisal fabric composites, with and without thermal treatment (at 60°C for 72h) on the fabric, thermal characterization by TGA and the manufacturing process by compression molding are presented.
Abstract: This research proposes the development of polymeric composites reinforced with natural fibres to become stronger the damaged timber structures and proposes thermal and mechanical characterization of these composites. Fibres with larger structural applications are glass and carbon fibres but the use of natural fibres is an economical alternative and possesses many advantages such as biodegradability, low cost and is a renewable source. Woven sisal fabric was submitted to heat treatment before moulding and the influence of moisture content of fibres on the composites behaviour was observed. The paper presents mechanical characterization by tensile and flexural strength of woven sisal fabric composites, with and without thermal treatment (at 60 °C for 72 h) on the fabric, thermal characterization by TGA and the manufacturing process by compression moulding. Experimental results show to sisal/phenolic composites a tensile strength and a flexural strength value of 25.0 MPa and 11.0 MPa, respectively, independent to the use of sisal fibres with or without thermal treatment.

TL;DR: In this paper, the effects of chemical treatment on the surface characteristics of sisal fibres and their physical/mechanical properties have been investigated, and it was observed that fibre tenacity increases with increase in NaOH concentration.
Abstract: The effects of chemical treatment on the surface characteristics of sisal fibres and their physical/mechanical properties have been investigated. The sisal fibre was extracted by manually beating the sisal leaves with a smooth edged stick followed by chemical modification of the fibres using alkaline treatment method with NaOH at different concentrations and time intervals and at a constant temperature of 65 oC. The surface morphology and physical and mechanical characteristics of the treated and untreated sisal fibre samples was studied. The Scanning Electron Microscope (SEM) micrographs revealed the rough surface topography of the sisal fibres caused by alkali modification which increased with increased concentration. Furthermore it was observed that fibre tenacity increases with increase in NaOH concentration. However, beyond 20 % NaOH concentration, decrease in tenacity is observed. Fibre breaking extension increases with increase in NaOH concentration. Moisture regain decreases with increase in NaOH concentration.

TL;DR: In this paper, the authors presented the recyclability analysis of PLA/Sisal biocomposites comprising sodium bicarbonate treated Sisal fibers (30.5wt).
Abstract: This study presents the recyclability analysis of PLA/Sisal biocomposites comprising sodium bicarbonate treated Sisal fibers (30 wt%). The biocomposites were recycled (8 times) using the extrusion process. The tensile strength of injection molded biocomposites declined by 20.9% up to the third recycle. The dynamic mechanical analysis revealed a severe reduction in storage and loss modulus beyond third recycle. The morphological and thermal characterization of recycled biocomposites also revealed severe fiber and matrix degradation. The infrared spectroscopy exhibited hydrolysis as one of the causes of PLA degradation after recycling. The recycling of PLA/Sisal biocomposites beyond third recycle is not recommended. However, the biocomposites recycled up to third recycle can be used for making products for low to medium strength non-structural applications.

TL;DR: In this article, groundnut shell particles were chemically modified and added to the polymer to form novel bio-based composites and the composites were characterized for some mechanical properties according to ASTM standards.
Abstract: In recent years, there is a growing interest in the use of bio-fibers as reinforcements for thermoplastics and thermosets. A lot of research work has been performed all over the world on the use of natural fibers such as flax, bamboo, sisal, hemp, and jute as reinforcing materials for the preparation of various types of composites. In this study, the agricultural residue such as groundnut shell particles were chemically modified and added to the polymer to form novel bio-based composites. Composite boards were fabricated by randomly distributed groundnut shell particles of different grain sizes and epoxy resin with volume percentages of 70:30, 65:35, and 60:40. The composites prepared were characterized for some mechanical properties according to ASTM standards. The highest tensile strength, tensile modulus, MOR, and impact strength were observed for the sample having groundnut shell particles and epoxy resin proportion 60:40 and 0.5 mm particle size. However, the sample with 60:40 particles and resin pro...
