摘要:
Multimaterial structures comprising carbon fiber reinforced plastics (CFRPs) and titanium alloys can be widely utilized in the aerospace and automotive industries to achieve optimal weight reduction and reliable structures. In this study, three-dimensional-printed titanium (3DP-Ti) adherends prepared using selective laser melting were co-bonded with woven-fabric carbon fiber reinforced phenolic matrix composite by hot pressing. Upon controlling the scanning speed and path, the 3DP-Ti adherends were prepared with various porosities and macro structures on their surfaces, and the influences of these surface structures on the lap-shear strengths and fracture morphologies of the 3DP-Ti adherends were investigated. The lap-shear tests of the lap-shear joints with flat 3DPTi and pyramidal-macrostructured 3DP-Ti displayed the cohesive failure of the phenolic resin matrix. In contrast, the specimen with cylindrical macrostructure exhibited CFRP fracture and delivered the highest bond strength of 20.6 MPa, which was 18-64% greater than the strength of the lap-shear joint with the conventional Ti alloy plate and 3DP-Ti adherends with flat surface and pyramidal macrostructure. The major possible mechanisms behind the failure mode transition and the highest bond strength included the mechanical interlocking between the cylindrical macrostructure and CFRP.
