UHMW warping while fusing to glass filled HDPE
UHMW warping while fusing to glass filled HDPE
(OP)
Hello,
I am trying to fuse UHMW to glass filled HDPE tape and am having the UHMW warp and create large creases. My setup now is inside a vacuum bag I have a silicone heating blanket at 400F on top of the glass filled HDPE with the UHMW under that and lastly it sits on a steel sheet to help keep it flat.
I am thinking possibly I am ramping up the temperature too quickly or that I need a mechanical press to create more pressure..
Thank you

I would heat evenly and slowly from both sides and cool evenly and slowly on both sides.
You might also need to apply the glass fibre to both sides if that is possible.
