Dynamics of semi-flexible fibres in viscous flow [PDF]

open access: yes, 2007
The dynamics of semi-flexible fibres in shear flow and the effect of flexibility on the swimming speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers ...

Properties of threads created by thread inserts

open access: yesResearch in Agricultural Engineering, 2003
Several techniques are at disposal for production or repair of internal threads. The repair of threads by means of flexible thread inserts and the repair of threads by means of sold thin walled thread inserts belong to the most important ways.
