ABSTRACT
Fibre-reinforced composites are extensively required where the need for mechanical strength is one of the significant parameters. Industries such as automotive, aerospace, marine, and oil and gas extensively employ fibre-reinforced composite materials, and such industries are considered to be key players in the global market for composites. Fibre-reinforced composites have several kinds of construction features with a wide range of variables, such as the appropriate selection of material components, fibre density, proper fibre orientation, composition of composite materials, composite thickness, composite density, composite structure, fabrication methods, and the use of mixed or hybrid reinforcements from natural or synthetic sources. Engineering thermoplastics such as polyether ether ketone, polyphenylene sulphide, PA, and PC are mainly used in the aviation industry, due to their good fire- and smoke-resistant properties, complying with the flame and toxicity regulations of the aviation sector. Coconut fibre–reinforced soil blocks performed better in terms of compressive strength than oil palm and bagasse fibre–reinforced soil blocks. Due to its good strength, durability, high tenacity, and resistance to salt water, sisal fibre–reinforced composites can be used in a cement matrix.
