Quite Interesting composite facts

Hydroscopic verses hydroscopic moisture in composites materials
Following the last post about Composite terminology here's a pop quiz which we had in the office regarding an email about hydroscopic verses hygroscopic.

If you don't know what it means:
hygroscopic =Readily absorbing moisture, as from the atmosphere.
1.Of a substance: tending to absorb moisture from the air L18


Something that's important to consider with composites. Our conversation was about the use of the word 'hydroscopic'. Read more to find out why:


If you are using a dictionary pre 1993 you might find this meaning:
hydroscope (noun): An optical device used for viewing objects far below the surface of water.

If you are using a dictionary, post 1993 (Oxford English definition) you will find this: The words mean exactly the same thing, (‘due to common usage’)
hydroscopic (adj) [ORIGIN from HYDRO -+SOL(UTION]
=hygroscopic 3

We all realised that our ages, combined with the age of our school dictionaries and education would probably provide a few more of these in the future.
If you have any more we'd love to hear them.
Thank you to Sgt Nik Badham for this QI moment.
