TL;DR: In this paper, a study of alkali-activated composites reinforced with sisal fibres was conducted, and the composite mechanical behavior was assessed through both indirect tensile and compressive tests.
Abstract: There are currently still some sustainability-related issues that need to be tackled within the construction sector. Namely, cement production is accountable for nearby 5% of the worldwide total CO2-eq release. Therefore, environmentally viable and economically sustainable solutions need to be pursued in order to mitigate the use of Portland cement. The incorporation of industrial waste in concrete compositions, such as fly ash (from coal combustion in power stations) is a feasible alternative. The properties of these residues may be enhanced through alkaline activation, which is able to yield aluminosilicate-based materials with excellent physico-chemical properties. Nonetheless, these materials exhibit a brittle behaviour. Therefore, the present work addresses the study of alkali-activated composites reinforced with sisal fibres. For that purpose, alkali-activated Class F fly ash was mixed with natural fibres and the composite mechanical behaviour was assessed through both indirect tensile and compressive tests. Four different fibre contents, in wt % of fly ash (0, 0.2, 0.6 and 1%), two fibre lengths (13 and 50 mm) and four curing periods (14, 28, 56 and 112 days) were considered. Results confirm that the post-cracking response of these composites was improved with the inclusion of sisal fibres. In general, higher residual tensile strengths and dissipated energy were observed for the lengthier fibres, i.e., 50 mm.

TL;DR: In this paper, the physical and mechanical properties of sisal fiber and yarn of Moroccan origin were investigated by FTIR spectroscopy and thermogravimetric analysis, which revealed an interesting potential to use the Moroccan sisal yarns in development of bio-sourced composite materials.
Abstract: This work aims to investigate the physical and mechanical properties of sisal fiber and yarn of Moroccan origin The cellulosic and non-cellulosic constituents of the Moroccan sisal fiber were identified by FTIR spectroscopy The thermal properties were studied by thermogravimetric analysis The hydrophilicity of the fiber was evaluated by the contact angle The results show that the sisal fiber has a low thermal stability The mechanical properties of the fiber analyzed by the Impregnated Fiber Bundle Test (IFBT) method show that the porosity of the impregnated yarns and the twist angle of the yarns influence the elastic modulus of the sisal fiber The physical and mechanical properties of the manufactured sisal yarns were also characterized and analyzed The obtained results reveal an interesting potential to use the Moroccan sisal fiber in development of bio-sourced composite materials

TL;DR: In this article, the tensile strength of varying glass/sisal and glass/jute contents within the composites were compared and the effect of hybridization was analyzed, and it was suggested that flax is an appropriate natural fiber to replace E-glass for applications requiring similar strength.
Abstract: The improvement in mechanical properties of biodegradable and sustainable materials like natural fibers turns out to be exceptionally appealing from the financial and biological perspectives. This is achieved by hybridization technique in which different fiber orientations can be adjusted in various arrangements providing variety in its properties. In this study, the authors used different natural fibers in hybridization with glass fibers. The tensile strength of varying glass/sisal and glass/jute contents within the composites were compared. Besides, the effect of hybridization was analyzed. Results revealed that all hybrid composites show low tensile strength as compared to the non-hybrid composites. However, in hybrid composites, the laminate containing a single layer of sisal fiber has shown almost the same tensile strength as non-hybrid composites. Based on results, it is suggested that flax is an appropriate natural fiber to replace E-glass for applications requiring similar strength.
