Hi All,
I have tried to find some info on here but possibly did not use the same search terms so please excuse me if this has been repeated.
I have made some CF panels on a glass sheet using 2 x 200gm² sheets pressed together. In one case i have used peel ply on the reverse to clear excess resin.
I have noted that these parts and panel came out soft and flexible. It also has a slight wrinkled surface when folded or flexed.
The flexibility can be compared to that of a common computer mousepad.
Anyone had this happen or have an explanation ?
The only reason I can possible think of is ambient temperature, I remember the days where pretty cold and humid during and my workshop is an open space.
I have also let the parts rest for a few says hoping that they would cure and harden a little... but no luck.
Seems like this panel and other parts I made during those days have all come out the same way...

Hey all.... After reading the replies, remembering what happened and calling the suppliers ... I found out what went wrong
I had purchased lower viscosity resin thinking that it would produce less air bubbles during the vacuum process.
It occurs that this resin has a slightly different mixing ratio and is more sensitive to temperature.
Thanks again for all the helpful input from everyone, nice to see how accurate all the answers are.

I reckon this must be a resin mixing error or just too cold to cure??
