fiber bundle
[/ˈfaɪbər ˈbʌndəl/]
nounpl: fiber bundles
fibrado (ou feixe fibrado)
1. A topological structure consisting of a base space with fibers continuously attached at each point, forming a mathematical object studied in topology and differential geometry
The Möbius strip is an example of a non-trivial fiber bundle over a circle.
A fita de Möbius é um exemplo de um fibrado não-trivial sobre um círculo.
2. In material science, a collection of individual fibers grouped together as a single structural unit
The fiber bundle reinforces the composite material's tensile strength.
O feixe de fibras reforça a resistência à tração do material composto.
3. In biology, a cluster of nerve or muscle fibers grouped together
A nerve fiber bundle transmits signals from the spinal cord to the extremities.
Um feixe de fibras nervosas transmite sinais da medula espinhal para as extremidades.
Fiber bundle is primarily a technical and academic term used in mathematics, physics, and engineering. In Brazil, 'fibrado' is the standard translation used in university mathematics programs and scientific literature. The term is essential in advanced topology courses and differential geometry, particularly when studying smooth manifolds and gauge theory. In industrial contexts, particularly in composite materials manufacturing in both the USA and Brazil, the concept is discussed but often using more colloquial expressions like 'feixe de fibras' or 'aglomerado de fibras'.
