FIBER

Fiber is a natural or synthetic substance that is significantly longer

than it is wide. Fibers are often used in the manufacture of other

materials. The strongest engineering materials often incorporate

fibers, for example carbon fiber and ultra-high-molecular-weight

polyethylene.

Natural fibers develop or occur in the fiber shape, and include those
produced by plants, animals, and geological processes. They can be

classified according to their origin:

Vegetable fibers

Wood fiber

Animal fibers

Mineral fibers

Biological fibers
