Cure kinetics of a composite friction material with phenolic resin/rubber compounds as organic binder

Abstract

Cure kinetics of a friction material with different proportions of rubber/resin as organic binders are investigated. The effect of including two different phenolic resins with different Btransformation times is also analysed. An experimental characterisation is done using both a moving die rheometer and an industrial press. Then, predictive models based on Kamal-Sourour, Isayev, and Claxton-Liska equations are defined. Results showed that a higher amount of resin delivered lower induction times and better fitted phenomenological methods. Higher content of resin and resin with lower B-transformation time led to faster curing reactions at laboratory and industrial scales. Samples with no resin presented an induction time that greatly depended on temperature and fitted worse than the models.

Effects of Pre-Curing on the Structure and Properties of Paper-Based Materials

“…Zhang et al explained that the performance of materials is directly related to the curing degree of resins, which affects their viscoelastic behavior and leads to changes in the mechanical properties of materials [ 17 ]. In terms of friction materials, Pablo et al discussed the important influence of resin content on the curing rate [ 18 ]. Most literature reported the relationship between the amount of resin and friction performance under different working conditions [ 1 , 19 ].…”
