plastic
1. any one of a large number of synthetic usually organic materials that have a polymeric structure and can be moulded when soft and then set, esp such a material in a finished state containing plasticizer, stabilizer, filler, pigments, etc. Plastics are classified as thermosetting (such as Bakelite) or thermoplastic (such as PVC) and are used in the manufacture of many articles and in coatings, artificial fibres, etc.
2. Fine artsa. of or relating to moulding or modelling
b. produced or apparently produced by moulding
3. Biology of or relating to any formative process; able to change, develop, or grow

acrylic fiber
A synthetic polymer fiber.
fiberglass
The generic term for a material consisting of extremely fine filaments of glass that are mixed with a resin to give the desired form in a mold. Layers of this combination are laid or sprayed into the mold.

plastic
[′plas·tik] (materials)
A polymeric material (usually organic) of large molecular weight which can be shaped by flow; usually refers to the final product with fillers, plasticizers, pigments, and stabilizers included (versus the resin, the homogeneous polymeric starting material); examples are polyvinyl chloride, polyethylene, and urea-formaldehyde.
(mechanics)
