Thickness control at sharp curvature.
Thickness control at sharp curvature.
(OP)
Hi i was wondering if anyone here as had experience resolving issues of over thickening at radius (example: corner of a U-shaped plate). I suspect the radius of curvature is too small at the bend, and is restricting resin flow, hence leading to areas where thickness becomes too high. A possible solution I was thinking was to reposition (or add) vacuum ports closer to the other side of the radius to assist with the flow.
Has anyone come across this issue and could provide some insight? Thanks in advance.

Thanks again for your input.
I was thinking along the lines of a thin rubber sheet which could conform the the contour more easily than a stiffer rubber sheet under vacuum. If the solution calls for essentially a rubber male mold, then I imagine it would take more than just the vacuum pressure to consolidate the intensifier against the ply.
