Abstract
The investigation of this work has the objective of studying the failure modes of hybrid laminates composites reinforced by bidirectional E-glass fiber and AS4 carbon impregnated with polymer resin (NOVAPOL L120). The test specimens were initially subjected to mechanical tests of uniaxial traction, three-point bending and interlaminar shear ILSS (Short beam). The fractographic analysis of the final fracture of the laminates was performed by scanning electron microscopy (SEM). The fracture aspects in the fiber / matrix interface region were detailed, so it was possible to determine the direction of crack propagation and to characterize the fractures caused by the loading action.
