Fiber Natural fibers include those produced by plants, animals, and geological processes and can be classified according to their origin: 1  Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, ramie, sisal, bagasse, and banana. bundle of optical fibers. Fiber or fibre (from the Latin fibra) is a natural or synthetic string used as a component of composite materials, or, when matted into sheets, used to make products such as paper, papyrus, or felt.

Processed materials We call materials that have not yet been processed raw materials. Raw materials are made into other things. When raw materials are in the form in which they are found in nature, we can call them natural materials. A natural material is any material that comes from plants, animals, or the ground.NSTRUCTIONS: 1  Your task is to find examples of processed materials in the world around you, particularly non-metals. 2  You must look at why that material has been used and how its properties make it useful to us.
