Hi
We have been asked to produce a bearing ring from Silicon Resin Bonded Fabric with a strengthining Aluminium sheet bonded to one side(simple). But! the rings hve to pass a 500 hour test of imersion in Skydrol hydralic oil at 130 deg C, the adhesives used so far have not lasted 100 hrs before...
I've been looking into wood extrusion and wondered if instead of a wood filler a cotton based filler has ever been tried.
I work in bearing cage manufacturing process
and at the moment we used rolled phenolic cotton tubes. An extruded tube/rod would help reduce the cost's
