Over ts entire service life, it can be xp sed to a range of corrosive enviro men s. Thus, in the orking lif o composit ma erial, it is mporta t o understand t fect o f co rosive environment. According t the au hor’s knowl dge, he effect of different aviatio oils was not yet stud ed. Therefore, bi-directional carbon fibre reinforced composites wer subjected to oil imm rsion tests, us ng an Aviation gasoline (Avgas-100LL), Aviation Turbine Fuel (ATF-K50) and an extra high performance lubricating fluid (OX -38), in orde to study the effect of fluid abs rption behaviour on tensile, flexural and impact strength properties of bi-directional ca bon fibre r inforc composit es. These oil solut ons affect the tensil , flexural properti and the impact strength. However, for all tests performed, the high- performance lubricating fluid promotes the lowest values compared to the Avgas and Aviation Turbine Fuel. © 2020 The Authors. Published by Elsevier B.V.

Over its entire service life, it can be exposed to a range of corrosive environments. Thus, in the working life of composite material, it is important to understand the effect o f corrosive environment.
