Abstract
Methods and apparatus for tooling in layered structures for increased joint performance are disclosed. A disclosed example method includes placing a tool onto a first substrate to define an impression in the first substrate, curing the first substrate, removing the tool from the first substrate to define a joint interface corresponding to the impression, and coupling, at the joint interface, the first substrate to a second substrate.
Claims15
A method comprising:
- placing a tool onto a first substrate to define an impression in the first substrate, the first substrate having first plies;
- curing the first substrate;
- removing the tool from the first substrate to define a joint interface corresponding to the impression, the removal of the tool from the first substrate to define a tab with a first undercut in the first substrate, the tab having a t-shaped cross-sectional profile;
- and
- coupling, at the joint interface, the first substrate to a second substrate, the second substrate having second plies, the second substrate having an opening with a second undercut, the tab to be inserted into the opening along a direction that is orthogonal to which planar surfaces of the first and second substrate extend.

A method comprising:
- placing a tool onto a functional film to define an impression in the functional film;
- removing the tool from the function film to define a bond interface corresponding to the impression, the removal of the tool to define a first undercut in the impression of the functional film;
- and
- coupling, at the bond interface, the functional film to a substrate, the substrate including a tab with a t-shaped cross-sectional profile, the substrate coupled to the functional film with the tab inserted into the impression along a direction that is orthogonal to which planar surfaces of the functional film and the substrate extend.
