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.
Claims22
A method comprising:
- 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.
2 more elements
A composite layer assembly comprising:
- a first composite structure including at least two plies, the first composite structure having at least one indentation;
- and
- a second composite structure including at least two plies, the second composite structure coupled to the first composite structure via the at least one indentation.
An interlocked composite structure comprising:
- first plies layered around an opening, the opening including:
- a first narrow portion extending from a first interface surface at a first side of the first narrow portion, and
- a first wide portion extending from the first narrow portion at a second side of the first narrow portion opposite the first side;
- and
- second plies extending from a second interface surface, the second plies layered to define a protrusion including:
- a second narrow portion extending from the second interface surface, and
- a second wide portion extending from the second narrow portion, the first interface surface and the second interface surface to contact one another such that the second narrow and wide portions of the protrusion are inserted into the first narrow and wide portions, respectively, of the opening of the first plies.

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;
- and
- coupling, at the bond interface, the functional film to a substrate.
