  • Abstract:
  • Composite materials are used in several engineering applications, where can be exposed to a range of corrosive environments during their in-service life. Thus, it is necessary understanding the impact of a corrosive environment in the working life of composite. Therefore, glass fiber/epoxy composites were subjected to oil immersion tests, using universal multi-grade engine oil (20W-40) and an extra high performance hydraulic brake fluid (DOT3), in order to study the effects of oil absorption behaviour on flexural and tensile strength properties of glass fiber/epoxy composites. The study has been completed with weight changes, after and before immersion both solutions affect the flexural properties and the tensile strength. Flexural and tensile behaviours are the main mechanical properties evaluated, although they are supplemented with Rockwell hardness, obtaining complete mechanical information. However, for all tests performed, the automotive brake fluid (DOT 3) promotes the lowest values comparatively to the automotive engine oil (20W40). Nowadays, composite materials are used in several engineering applications, as a consequence of their high specific strength and stiffness, competitive cost, good static and dynamic properties, good resistance to corrosion and simplified fabrication. In this context, these materials are exposed at different environment conditions, which affect significantly their mechanical properties. Glass fiber/epoxy composites were subjected to oil immersion tests, using an universal multi-grade engine oil (20W-40) and an extra high performance hydraulic brake fluid (DOT 3), in order to study the effects of oil absorption behavior on flexural and tensile strength properties of glass fiber/epoxy composite. Both solutions affect the flexural properties and the Tensile strength. However, for all tests performed, the automotive brake fluid promotes the lowest values comparatively to the automotive engine oil.
