- Abstract
The ply stacking sequence of Carbon Fiber Reinforced Plastic (CFRP) has influence on failure strength of bonded joints made by this CFRP substrates. Existing researches have demonstrated that the specific influencing mechanism is related to the position of 0 ply inside the substrates. Tension load of such joints normally keeps increasing until delamination between 0ø ply and its neighboring plies happens, and the position of 0ø ply determines whether it delaminates easily or not. This mechanism takes effect in both local and global ways. Laminates with 0ø plies further from the adhesive interface are found to be more resistant against tension loading because this configuration makes the local crack propagation more complex. On the other hand, 0ø plies being the surface layer of laminates brings higher bending stiffness globally, reducing intralaminar peel stress caused by eccentric loading of single lap joint, thus increase joint strength. In the case of quasi-isotropic symmetric laminates, the local and global factors are working oppositely and coupling with each other. A bonded joint made with two composite substrates of different stacking sequence can eliminate this coupling effect and draw reliable conclusion
