The Aircraft Spruce catalog says "NEVER use micro between glass layers." Is it acceptable to use flox or some other type of filler between glass layers?
Thank you,

The basic answer is NO! The strength of multiple layers of fiberglass comes from them being together with no voids or other material between them. A composite sandwich (glass-foam-glass) can also be made very strong.rv9builder said:The Aircraft Spruce catalog says "NEVER use micro between glass layers."

You should never use micro between layers, but flox is sometimes acceptable. There are usually other techniques that are stronger and lighter than flox to build up an area that should be explored first. Describe your problem in more detail and pehaps we can assist you with a solution.rv9builder said:The Aircraft Spruce catalog says "NEVER use micro between glass layers."

That's the primary one, but if you lay a bunch of plies to make a hard point, and you need to smooth the transition around the build-up, you can lay in some flox in order to avoid any voids in the layup. Generally, the use of flox between layers is avoided because of weight, not strength. It is extremely hard and strong, as you probably know, but weighs quite a bit. Glass cloth with grab flox quite readily and not let go. Not so with with micro, which will stick to the cloth, but has a very, very low shear value and the glass will easily seperate from the micro with just a minimal shear load.Finley Atherton said:The only time that flox is "sort of" used between glass layers that I am aware of is when two lay-ups of glass meet to form a corner over a foam core. In this situation the corner of the foam is removed after one of the sides has been layed-up and allowed to cure. The resulting void is filled with flox and the other side is then glassed over the wet flox. So you end up with two glass lay-ups joined by flox at the corner.
