| An experimental campaign was made for the assessment of the Single Lap Shear Strength of titanium-carbon-based fibre metal laminates. Six titanium surface preparation methods were designed based on new and standard conditions defined for conventional fiber metal laminates. Their mechanical behavior was tested and failure characterization at metal-composite interface with a parametric study based on strength, stress and ratio of dominant failure type. The highest single lap shear (15.43 ± 1.23 MPa) was observed for laminates after sandblasting + sol–gel treatment and it was 60 % higher than for Scotch-Brite + sol–gel. The lowest value (4.78 ± 1.17 MPa) for was noted after plasma process. For phosphate-fluoride process and sandlasting + primer the results were comparable between 6.26 − 7.03 MPa. Three dominant cracking models under shear stresses were defined adhesive, mixed and cohesive. For plasma method with the lowest surface roughness failure at the metal-composite interface was noted. Laminates with modified surface by phosphate-fluoride process with primer and sol–gel coating showed delamination at the oxide layer-primer/sol–gel layer interface and at the primer/sol–gel layer-epoxy interface. Modification of titanium laminates by sandblasting and Scotch-Brite abrasion with a sol–gel resulted in cohesive failure which occurred in the volume of the composite. It has been observed that for titanium surfaces, if shear strength is the criterion, it is desirable to achieve high surface roughness and the external coatings (such as primer or sol–gel) are recommended to improve the chemical properties of the FML. The most effective titanium surface preparation is proposed in terms of the application of titanium in second-generation fibre metal laminates. |
