Lignocellulosic/natural fibre and glass fibre-based hybrid composites are considered as high-performance composites but very limited numbers of researchers worked on substituting sugar palm fibre with glass fibre in hybrid composites. The main goal of this research to investigate the effect of various treatment such as 6% alkaline (TNSP), 2% silane (TSSP) and combined 6% alkaline–2% silane (TNSSP) on physical and thermal properties of sugar palm/glass/thermoplastic polyurethane hybrid composites were carried out. Taking into account of physical properties, the combined alkaline–silane treated hybrid composites (TNSSP) showed the lowest density, thickness swelling, and water absorption as compared to other composites. The good thermal stability was discovered for treated as compared to untreated sugar palm fibre based composites (UTSP). Overall, the treated sugar palm/glass/thermoplastic polyurethane hybrid composites suitable for the fabrication of automotive components.

Physical and thermal properties of treated sugar palm/glass fibre reinforced thermoplastic polyurethane hybrid composites

The automotive and aerospace industries are in continuous struggle towards the development of lightweight components to improve fuel efficiency. Thermoplastic matrix composites offer distinct advantages in terms of weight reduction, recyclability, specific strength, corrosion resistance, cost-efficiency, and design versatility. Natural fibres owing to their biodegradability, abundance in nature, and low cost not only expand the scope of these materials but also curtail the dependency on petroleum-based products. This review presents a comprehensive state of the art in natural fibres properties; mainly plant fibres, and their use as composite reinforcement followed by the textile technologies used to fabricate the engineered architectures. The review also covers the properties of commonly available thermoplastic matrices and the composite fabrication techniques to enable the selection of the precise material and process for any specific product development. Finally, the mechanical properties of natural fibre reinforced thermoplastic composites are reviewed and the key challenges that need to be dealt with are highlighted.

Environmental benign natural fibre reinforced thermoplastic composites: A review

Increasing demand for non-biodegradable plastics undesirably leads to their accumulation and calls for an appropriate solution for this global crisis. Environmental impacts of PET waste have long been addressed; although some remedies have been proposed, their extensive use in the modern world use demands new studies and recycling techniques. It shows the inadequacy of previous solutions to eliminate this environmental problem. Therefore, researching this subject should not be considered an insignificant issue. Distinctively, this review article has a specific reliance on the use of recycled PET fibers in the production of high-consumption and value-added products that, in addition to considering environmental aspects, can also be attractive to the market. This article deals with recent studies in three product categories (concrete, nonwoven fabrics, yarns) made from recycled PET fibers and shows the high potential of PET fibers for the future industry.

Recent Studies on Recycled PET Fibers: Production and Applications: a Review

The continuous demands for reducing environmental impact and energy consumption are the major driving factors for the development of natural fiber (NF)-reinforced composites (NFRCs). The huge demand for sustainable materials in industries leads to the usage of NFs in product developments. These NFs are more attractive due to their lightweight, cost-effectiveness, ease of availability, and environmentally friendly aspects. Green composites are the best alternatives in place of petroleum-based composites which meet the current industrial requirements. In recent years, researchers are more focused on the development of NF composites as a potential candidate in real-life applications due to economic advantages. This review gives a brief overview of NFs introduction, types, economic aspects, and the recent developments in NFRCs with an analysis of mechanical, thermal, and dielectric properties. Moreover, the water absorption behavior, applications, and challenges in using NFs are also studied in this review. Additionally, this review will motivate the researchers for further developments and exist as foundation literature for upcoming researchers.

The effect of fabric weight, needling density, and blend proportion of jute and polypropylene fibers on water absorbency, fabric thickness, and fabric density has been studied. Box and Behnken experimental design has been used for preparation of needle-punched nonwoven fabric samples. Cluster analysis has been used to study the grouping behavior of the variables. Water absorbency increases with the increase in jute content. Water absorbency decreases with the increase in fabric weight and needling density. Highest water absorbency (720%) of the fabric can be obtained at 60% jute content level with lower needling density and lower fabric weight. The fabric thickness increases with the increase in jute content. At higher level of jute content, with the increase in needling density, the fabric thickness shows decrease in trend. At higher level of fabric weight and higher needling density, with the increase in jute content, the fabric thickness shows a decrease in trend. Maximum fabric density can be obtained...

Nettle is a common herbaceous plant, which regroups 30–45 species. It is part of the Urticaceae family such as ramie (Asian nettle, Boehmeria nivea) and belongs to the genus Urtica. The stinging nettle (Urtica Dioica) is the most prominent species in Europe and Himalayan ranges. This fibre also belongs to an ancient textile fibre. In this chapter deals with different aspects of sustainable process of production of fibre, methods of fibre extraction and their advantages, properties of nettle fibre, products from nettle and its blends. A comprehensive effort has been made to revamp the potentiality of sustainable development of fashionable textile and industrial materials from nettle fibre as well as form its byproducts. Overall, chapter covers various nettle-based handicraft and apparel products for luxury sector and their proper disposal.
