RUBBER FRICTION

Geschriben am 27-03-2013

Why investigating & 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 & 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 discover friction measurement results between LSR SILICONE, NBR ... and STAINLESS STEEL, GLASS ... , influence of rubber hardness, influence of rubber surface and ... lubrification !
