I'm looking into fillers to add to a polycaprolactone based material to increase the friction significantly, and also the surface roughness. I've used powdered rubber at 840 micron but at the fill required it made the material very flexible. The end material needs to retain the strength of the poly-caprolactone and also be rough and "grippy" to touch.
Any ideas of what I could use? Anything added needs to be stable up to 100 degrees C as the material is designed to be mouldable (hence using polycaprolactone)
