ABSTRACT
In comparison to typical fibre-reinforced polymer composites, hybrid polymeric composites or green composites are freshly designed composites. Green composites are a new generation of environmentally friendly composite materials that are both renewable and biodegradable. The qualities of the separate components determine how hybrid composites behave. In these hybrid composites either more than one reinforcing phase with a single matrix phase is present or there are numerous matrix phases with only one reinforcing phase or several reinforcing phases are used. Artificial fibres, natural fibres, or a combination of both are used to create hybrid composites. Natural fibres like coir, jute, hemp, sisal, bamboo, and other fibrous materials have excellent mechanical qualities such as stiffness, flexibility, and modulus. Natural fibres provide a number of advantages. Natural fibres have several advantages, including low cost, light weight, ease of production, and environmental friendliness. The factors like fibre content, matrix to fibre connection and arrangements of fibres, orientation, length of individual fibres, amount of intermingling of fibres, and fibre to matrix connection play an important role in hybrid composite. Aramid, glass, polyethylene, and carbon are the most prevalent synthetic fibres. In polymer matrix composites, stiffer and stronger fibres can be added to improve the quality and strength of the polymer. For aviation, wind turbine blades, automobiles, prosthetics, smart memory, ship construction, and bridge building, high performance composites have shown considerable promise. The characteristics, manufacture, use, and future trends of natural and synthetic fibre hybrid composites are discussed in this chapter.
