3 Reinforcing fiber terms

3.1 fiber; fiber A filamentous unit of matter with a large aspect ratio. 3.2 continuousfibre Fibers with a sufficiently large aspect ratio in continuous lengths (3.1). 3.3 staple fiber Short fibers of spinnable length (3.1). NOTE. Can be cut short during drawing, or cut into segments from continuous fibers (3.2). 3.4 reinforcement fiber The fiber (3.1) material added to the matrix can significantly improve its mechanical properties.
