- Abstract
- In this study, we investigated the influence of long-term oil absorption on mechanical properties of carbon fiber reinforced polymer (CFRP) composites for automotive gearbox to identify the adverse effects of lubricant oil on laminated CFRP composites and enhance their oil resistance. The laminated CFRP containing epoxy resin with high glass transition temperature was thermally stable, resulting in a low oil absorption rate. Moreover, as the oil absorption increased, the mechanical strength of CFRP was decreased. The uncured epoxy resins generated a microcrack between the carbon fiber and the resin, which leads to an increased oil absorption through the microcrack and thereby reduces the interfacial adhesion between the carbon fiber and the resin. Consequently, this study affords the optimal material parameters of CFRP for high oil resistance.
