BiPolarMoment
Mechanical
I'm working on a device where two PEEK surfaces are moved relative to each other in discrete fashion under load. In this situation overcoming the static frictional force is a concern as it is manually actuated. This motion is one time only for assembly so wear is not a significant concern.
I've been looking for frictional coefficients for these materials but I'm most interested in these specific pairing and that is not often given.
E.g. I've found one source for PEEK 450G dynamic coefficient as 0.4 and for 30% CFR PEEK dynamic coefficient as 0.19 (both dry vs. steel). What I don't know is the static coefficients which are presumably higher and perhaps not proportional. Additionally, I don't know the interaction between like/dislike polymers as in this case compared to vs. steel.
So if numbers can't be provided I'm still interested to discover what the heirechy of the friction couples might be.
CFR/CFR->CFR/PEEK->PEEK/PEEK?
or perhaps no notable difference?
