RUBBER FRICTION

On 27-03-2013

Why investigating and caracterizing friction with Hot Temperature Vulcanisable Elastomers - rubber?
- because friction is a key value for determining efforts / mouvements (these efforts are the consequence of “compression” / “deformation” ... and friction) in mounting currently,also in function
- for avoiding / knowing sticking
- for improving knowledge in this range of specific characteristics


How investigate and caracterize friction ? CHEVALIER has identified 2 existing main tests:

A: SRT pendulum (standardized)
 

B: friction block (standardized)

In that case, friction  (f)  will be
           F
(f) = ———
          M x g
 

In addition to the existing standard tests, different types of tests exist according to the applications /and customers .

Please detail your target and ask to get at jm.oudot@chevalier-cleret.fr the full INFORMATION LETTER Nr 87 we already published. You will dicover friction measurement results between LSR SILICONE, NBR... and STAINLESS STEEL, GLASS... , influence of rubber hardness, influence of rubber surface and... lubrification !
