Fibres are thread-like structures with thin, long, and flexible strands that can be broadly defined. Plants and animals are the two main suppliers of fibres. The fibres are spun into yarns, which are subsequently woven into the best fabrics. A single long fibre can provide yarn for a variety of fabrics on average. Natural Fibres are fibres that are obtained naturally from both plants and animals. These Fibres are a hair-like raw material that can be obtained directly from a variety of plants and animals. These fibres are created artificially by humans in industries where polymers are developed to make fabrics with the use of simple chemicals. Polymers are macromolecules made up of small, repeating subunits that have been joined together.
Composites are made up of two or more constituent materials that have diverse physical and chemical properties. When they're combined, they create a substance with attributes that aren't the same as their individual properties. The matrix and fibre are the two main components of a composite. The matrix serves as the material's foundation, while the fibre serves to reinforce it. Composites can incorporate core materials, fillers, additives, and surface finishes in addition to fibre reinforcements and matrix to give unique performance characteristics. When they are mixed, they form a material that is specialised to perform a specific task, such as becoming stronger, lighter, or more resistant to electricity. They can also help with stiffness and strength.
