Composites

[Simon G]

I've posted this question on the technical forum (the official one) and it seems like they are so back-logged that the answer may not come soon enough (I want to start layup this weekend). So perhaps someone with prior years experience (we are a new team) may give an opinion:

The rules state that fiberglass may not exceed 1/8" thickness. My question is on sandwich structure, i.e. if I make a 1 1/4" sandwich structure of 1" foam with two 1/8" thick fiberglass face sheets, would that be allowed?

Also, if I were to have two discreet 1/8" laminates, and joined them in a lapjoint, such that the overlap was 1/4" thick (plus bondline), would that be allowed?

I guess my core question (no pun intended) is whether the 1/8" refers to max thickness of an independently cured laminate, or to the whole structure?

Opinions would be appreciated, as I know that what is said here can't be considered official.

Thanks!!
