Hello all.
When comparing the stiffness results from a tensile test of a lay-up (0/90/+/-45 in differenct combinations) with the stiffness predicted using classic laminate theory (CLT), I have noticed that it's not uncommon for CLT to overpredict the stiffness. The measured stiffness is usually...
Hello.
We recently manufactured a larger CFRP sandwich article using OOA VBO technique and we were a bit surprised that the resulting prepreg appeared to contain much less resin than usual, and by this I mean that the fibers are visible in many places. This was especially appearant in the...
Hello.
I'm wondering if anyone has experience with using expired prepreg (i.e. expired freezer-life and not out-life).
The material in question is an epoxy/glassfiber woven prepreg which will be used locally as a corrosion barrier on a larger epoxy/carbon fiber structure.
I'm thinking that we...
Hello!
I'm trying to model a composite using the built-in solid laminate element type which requires me to specify a lay-up. However, it seems that none of my materials seems to be appropriate. I constantly get the message "invalid material type" when I try to select them in my lay-up editor...
