“…Since the density of the 'Pandanus utilis' bre is half the glass bre, industrial volume ratio was used instead of the mass ratio for adequate mixing of the natural bre and the polyester resin. [19] The tensile strength of the SFOT bre polyester composite was 8.32 ± 1.30 MPa, and 11.10 ± 2.53 MPa for SFST bre polyester composite. Based on a t-test, the calculated t value is 2.953 whereas the critical t value is 2.306, which con rms that there is a difference between the two mean values.…”

Composite materials made with synthetic fibres like E-glass, Kevlar or carbon have helped to provide a wide array of products to society with specific engineering properties. However, these materials have a high carbon footprint as well as being non-biodegradable. The use of natural fibre, as a substitution to these man-made fibres, has been studied and encouraging results are being obtained.In this study, the use of ‘Pandanus utilis’ fibre as a reinforcing agent in plastic was investigated with the aim of exploring specific properties such as the tensile strength of the fibre, its wettability and the effect of fibre length after treating the fibre with two different NaOH solutions. Results have shown that better reinforcement was obtained for the composites (11.10 ± 2.53MPa) with fibres subjected to a more aggressive treatment (2.5%NaOH for 2h) compared to the composite made with fibres having maximum tensile strength (168 ± 12MPa at 0.5% NaOH for 14h), due to a better hydrophilicity of the alkaline treated fibre (87.37° internal angle). Within the range of short chopped fibre length tested (6 to 15 mm), it was shown that there was a general decrease in the tensile strength of the composite.

Environmental concerns and the depletion of petroleum resources have spurred research into natural fibres as sustainable alternatives to synthetic fibres as the reinforcement phase in polymer composites. Given that the local availability of materials is a crucial component in the sustainability framework, there is a need to map out the fibres used to develop natural fibre composites across geographical regions to optimize local resource utilization. Through a systematic review of publications sourced from Scopus and Web of Science databases, this study examines the contributions made by Africa to develop green polymer composites. The bibliometric data from both databases were systematically merged, and bibliometric analysis was carried out to identify trends and relevant relationships and provide a more general insight into Africa's progress in the natural fibre polymer composite field. A meta‐analysis was then conducted to identify the natural fibres exclusively sourced from Africa that have been used to develop polymer composites. The study also discussed natural fibre classifications with respect to fibre type and form. Sisal, palm varieties (particularly date palm), alfa, jute and members of the Musaceae family (i.e., banana, plantain and enset) were found to be the most used African‐sourced fibres. This study is a step to creating a more extensive global natural fibre database that seeks to provide more precise knowledge, enhance research efficiency, and ensure the utilization of local materials in creating more sustainable composites.Highlights The use of local materials is a key component of sustainable development A natural fibre database can foster sustainability in the composite industry Egypt, Morocco, and Tunisia are leading Africa's composite research Research prioritizes composite material science over practical applications Sisal, date palm, alfa and jute are the most used natural fibres in Africa

“…A first comparison of the tensile strength of the natural fibre composite and the glass reinforced plastic (GRP) produced using the industrial procedure (fibre chopped at 6 mm length) in force at the local company was made. Since the density of the Pandanus utilis fibre is half the glass fibre, industrial volume ratio was used instead of the mass ratio for adequate mixing of the natural fibre and the polyester resin (Ramasawmy et al, 2017). The tensile strength of the SFOT fibre polyester composite was 8.32 ± 1.30 MPa, and 11.10 ± 2.53 MPa for SFST fibre polyester composite.…”

In this study, the use of Pandanus utilis natural fibre as a reinforcing agent in polyester was investigated with the aim of evaluating the tensile strength of the fibre, and its wettability based on two different NaOH treatments. Furthermore, the effect of the NaOH treated chopped fibre length on the tensile strength of the fibre composite was evaluated. The results have shown that a better tensile strength was obtained for the composites with the 2.5% NaOH treated fibres (11.10 ± 2.53MPa) as compared to the composite made with 0.5% NaOH treated fibres (8.32 ± 1.30 MPa), primarily due to a better wettability of the 2.5% alkaline treated fibre (87.37° internal contact angle) with the polyester resin. Within the tested range of short chopped fibre length (6 mm to 15 mm), it was shown that there was a general decrease in the tensile strength of the fibre composite.
