GLOSSARY |
COMPONENT | |
A distinct unitary element of a composite tool in the form of a layer* or a constituent of a layer. |
FIBER | |
A relatively short, slender, flexible element of macroscopic size and finite length and having a width and thickness of the same order of magnitude. A fiber is generally of staple length to facilitate its being spun, twisted, or otherwise secured together into a composite strand but may be shorter length requiring bonding, felting, or matting to form a strand or layer. It may be of animal (e.g., wool, rabbit hair), vegetable (e.g., cotton, jute, hemp), or mineral (e.g., asbestos, glass, metal) origin and may be either natural, modified, or synthetic. |
LAYER | |
A single thickness of material(s) in the form of a sheet(s) in side-by-side, coplanar relation; or particulate material arranged in continuity to constitute a distinct stratum. |
SHEET | |
A rectangular portion of material of finite length, whose width is greater than its thickness. | |
