Adhesion Systems in Power Transmission Belts

As with most rubber composites the adhesion system used in power transmission belts is based on an resorcinol/formaldehyde/latex (RFL) type system. General overviews of RFL adhesion systems from a tyre cord perspective have been previously published by Takeyama and Matsui [31], and more recently by Solomon [32]. Bonding with RFL systems is achieved through applying an RFL coating to the fibre structure prior to the 

Tests to assess the level of adhesion of fibre structures to rubber compounds can be divided into three classifications  

Cord pull out tests are commonly used to assess the adhesion between a single cord and a block of rubber compound. As the name suggests the tests concentrate on measuring the load required to pull a cord from a block of rubber compound. There are various
