The characterization of feldspar for electric porcelain and the behaviour of these materials after heating at 1230°C were studied. X-ray diffraction (XRD) and scanning electronic microscopy (SEM) were used to identify the present phases and the densification level. Feldspar sand was treated by flotation. The floated feldspar is constituted by microcline, quartz, and minor amounts of albite. The microstructure of sintered feldspar at 1230°C is essentially vitreous with open microporosities. The dielectrical properties of composites were characterized by using the induced courant method (ICM), which indicates that the charge trapping capacity depends on the mineralogical and chemical composition of feldspar.

“…By increasing the moisture content, the flow of electrical current rises on account of increased non-crystalline regions in the matrix phase [92,94]. The influences of fibre size, moisture, and water uptake on the dielectric behaviour of plant fibre-based composites have been investigated [95]. The results revealed that composites with same-sized fibres had a high mechanical performance and a smooth flow of electrical discharge.…”

There is an increasing demand for natural fibres worldwide due to their renewable and biodegradable nature. This paper reviews many aspects of natural fibres, focusing on the bast fibres of plants including hemp, flax, kenaf, jute, and ramie. Important characteristics of these plant fibres include physical, mechanical, dielectric, degradation, hygroscopic, and surface properties. These properties are highly variable, depending on both the chemical composition of the fibre and the environmental conditions. Retting and mechanical are the two main fibre extraction methods. When executed properly, retting produces the highest purity fibre; however, it is time-consuming and generates large amounts of wastewater. In contrast, mechanical extraction is faster and more environmentally friendly but results in lowpurity fibre. Despite the drawbacks of bast fibres (e.g. low thermal stability, low hygroscopicity, low surface energy), they have been successfully used in insulation, composite, and geotextiles and many further applications are currently being explored.

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
