32+ Fibre Reinforced Organic Matrix Natural Composites US. They are comprised of a variety of short or continuous fibers bound together by an organic polymer matrix. These are again classified into thermoplastic, thermoset and elastic.
Composite materials or more simply composites can be defined as materials resulting from the association of a continuous phase known as a matrix and a dispersed phase called thus wood may be considered as a natural example of a composite, lignin matrix strengthened with cellulose fiber.
Natural fiber shows comparatively poor fiber/matrix interactions, water resistance, and relatively lower durability. Instead, the matrix binds the fibres together and distributes the load. These are again classified into thermoplastic, thermoset and elastic. They belong to the category of natural fibre reinforced cementitious.
