Please explain the difference between short fibers and discontinuous fibers in FRP composites. Is there any difference with a specific length of fiber?
Hi Srinivasu Dasari,
You may want to refer to the following:
1) https://textbooks.elsevier.com/manualsprotectedtextbooks/9780750663809/static/composites/composites2a.htm#:~:text=They%20are%20classed%20by%20their,fibres%20have%20proportionally%20more%20ends.
2) https://www.sciencedirect.com/topics/engineering/short-fiber
(2) mentioned that short fibres are shorter than 1 mm in length.
Discontinous fiber that's according to the final use of it , that's mean that there is long and short fibers can be discontinous,
Short fiber
Synthetic fibres are available in two forms (i) staple cut ( discontinuous) and (ii) infinite long length filament ( continuous). The staple cut fibres could vary between 38,44,51, mm for making them compatible to cotton fibres and 68 to 120 mm for mixing them with wool fibres. Short fibres are those which are < 12.5 mm.
