continuous-filament fibre

Continuous-filament fiber refers to fibers produced through a spinning process where the resulting filaments are collected as continuous strands. This is most economically achieved through melt spinning, where a molten polymer is extruded through a spinnerette and solidified by cold air. These continuous filaments can be used directly or further processed.

In the context of plastics, continuous filaments are a key component in fiber reinforcement for polymer-matrix composites. Fibreglass, a common example, uses glass filaments in various forms, including continuous strands, to strengthen plastic materials. These reinforced plastics are used in manufacturing items like tanks, pools, and boat hulls.
