This paper is dedicated to the study of the mechanical behavior of a composite material reinforced with flax fibers with an orientation ±45o with respects to the load direction and symmetrical to the median plane, during a series of 4 creep-recovery tests with variable shear stress. During the entire testing process, a creep period of 1 hour was chosen and for the recovery period a minimum of 24 hours, this being necessary for the strain stabilization of the specimen. After the received information was processed the evolution of strain deformation was further analyzed during all cycles. After the load is removed, the material has the tendency to recover to its original dimension. As the strain deformation is rising on both periods of creep and recovery, this shows us the strain deformation depends on time and that after each recovery period the cumulative plastic deformations takes place.
