The material from which fabric is made. Fibers are of two types, natural and man-made. Man-made fibers are those manufactured from raw materials, such petro chemicals. Examples of man-made or synthetic fibers include: nytril, vinyl, glass, and anidex. Natural fibers are those made from vegetable or animal materials. Examples include cotton, flax, jute, wool, and silk.
Fibers can be used long or short (chopped). For composites, fibers are generally used long or in Mats or fabric. In this case the thermoset resin mainly acts as a binder. In thermoplastics, they are most of the time used chopped (relatively short lengths of very small cross-sections) as reinforcer. Glass fibers are the most used fibers. Syn. Extender, Reinforcer
Fibers, both visible and invisible, in a variety of lengths, thicknesses and colors integrated into the paper. Black lights must be used to check for invisible fibers, but visible fibers can be verified with the naked eye.
