Aircraft ski build
Posted: Thu Nov 25, 2021 7:09 am
I'm adding a layer of 3/16" UHMWPE to the base of an aluminum ski. There is a compound curve at one end. The ski is approximately 50" long, 8" wide with the center 6" being flat. The outside edge 1" is bent up at approximately a 20 degree angle. Looking for suggestions:
How to pre-bend the plastic along the edges to help add contact area and keep it on the original shape. This is important so the bolts used to hold more in provide more shear than tension and to keep the plastic flat and not scalloped.
Bonding the aluminum and plastic. I have a full vac bag set up and was planning on using it to provide clamping pressure. The idea is to flame treat the plastic to help with the bond. Recommended adhesives?
The edge will also be mechanically attached with bolts and there are 1/8" thick by 1" wide aluminum strips running the length of the ski. These provide some tracking, wear resistance, and help hold the plastic in place. The adhesive is helpful but not critical to keep the piece in place.
It'd be great to add some graphics to the white base. Suggestions on sublimation houses or DIY?
If you need more info please ask.
Thanks in advance, Kevin
