Al-CFRP UD deformation
Al-CFRP UD deformation
(OP)
I am working on Al(1.0mm) + CFRP (UD or Weave) (1.0mm) laminaton project.
The panel size is 1 X 1 meter (1m2) and the requirement is as flat as possible during - 20 and + 60 C temp variations.
It is impossible to keep it flat with this temp ranges but we should achieve it.
One idea is to use "Soft Glue" for the lamination of those two panels and make them flow a little.
We triedhard glue first and as expected it deformed a lot during that temp chanegs.
Also for other project I would like to have data for CTE (Thermal expansion) for Glass fiber UD and Carbon Fiber UD.
Thanks a lot in advance. !!!

UD IM-carbon/epoxy maybe +0.25 microstrain/K along fibres and +30 microstrain/K across fibres.
UD E-glass/epoxy maybe +10 microstrain/K along fibres and +40 microstrain/K across fibres.
All values (very) approx. NB: blakmax's +3 good for woven or roughly QI mixed-direction UD carbon laminate.
