title = "EFFECTS OF HYBRIDIZATION AND PLY THICKNESS ON CARBON/CARBON COMPOSITE LAMINATES STRENGTH AND TOUGHNESS",
abstract = "This work presents the results of an experimental study performed on carbon/epoxy composite materials manufactured using a ply-level hybridization technique to promote a pseudo-ductile failure and enhance their longitudinal fracture toughness. Three hybrid layup configurations with different total ply thicknesses and expected mechanical responses were selected for the investigation. The experimental campaign included longitudinal and transverse tensile tests together with in-plane shear and double edge notched tensile (DENT) specimens for the characterization of intralaminar longitudinal toughness. Although fracture toughness does not increase appreciably with hybridization, an effect on the failure modes is observed characterized by more widespread damage with distinctive fragmentation and pull-out. The combination of the thicker ply blocks with hybridization resulted in a diffused damaged scenario with clear advantages in terms of energy dissipation.",
