Abstract
A method of defining a rib structure within an iso-grid composite component according to an exemplary aspect of the present disclosure includes, among other things, defining a first rib at least partially with a uni-tape ply bundle at a first level, the uni-tape ply bundle including uni-tape plies and a first spacer ply, and defining a second rib transverse to the first rib at least partially with a spacer at the first level, the spacer including a second, different spacer ply, the spacer transverse to the uni-tape ply bundle such that the spacer is interrupted by the uni-tape ply bundle.

A method of constructing a rib structure within an iso-grid composite component comprising:
- forming a first rib at least partially with a uni-tape ply bundle at a first level, said uni-tape ply bundle including uni-tape plies and a first spacer ply, each of said uni-tape plies including a first material, and said first spacer ply including a second material that is different from the first material in fiber construction;
- and
- forming a second rib transverse to said first rib at least partially with a spacer at said first level, said spacer including a second, different spacer ply, said second spacer ply also including said second material, said spacer transverse to said uni-tape ply bundle such that said spacer is interrupted by said uni-tape ply bundle.
A method of constructing an iso-grid composite component comprising:
- forming a multiple of uni-tape ply bundles, each of said uni-tape ply bundles including uni-tape plies and a first spacer ply, each of said uni-tape plies including a first material and said first spacer ply including a second material that is different from the first material in fiber construction;
- and
- forming a multiple of spacers, each of said multiple of spacers including a second, different spacer ply also including said second material, each of said multiple of uni-tape ply bundles at different levels within a rib pattern such that each uni-tape ply bundle within a level of a first rib of said rib pattern is uninterrupted by at least one of said multiple of spacers which at least partially defines a second rib of said rib pattern transverse to said first rib of said rib pattern at said respective level.
A method of constructing an iso-grid composite component comprising:
- forming a uni-tape ply bundle including uni-tape plies and a first spacer ply, each of said uni-tape plies defining a first height, said first spacer ply defining a second height different from said first height;
- and
- forming a spacer including a second spacer ply, said second spacer ply defining a third height different from said first height, said spacer transverse to said uni-tape ply bundle such that said spacer is interrupted by said uni-tape ply bundle.
