Abstract
An iso-grid composite component according to an exemplary aspect of the present disclosure includes a spacer transverse to a uni-tape ply bundle, the spacer interrupted by the uni-tape ply bundle.
Claims20
An iso-grid composite component for a gas turbine engine comprising:
- a uni-tape ply bundle including uni-tape plies and a first spacer ply;
- a spacer including a second, different spacer ply, said spacer transverse to said uni-tape ply bundle, and said spacer interrupted by said uni-tape ply bundle;
- an interstitial ply layer adjacent said uni-tape ply bundle and said spacer;
- and
- wherein said uni-tape ply bundle and said spacer define a rib pattern, said uni-tape ply bundle at least partially defines a first rib of said rib pattern, said spacer at least partially defines a second rib of said rib pattern that is transverse to said first rib, and said interstitial ply spanning between a first sidewall of said first rib and a second sidewall of said second rib.

An iso-grid composite component for a gas turbine engine comprising:
- a multiple of uni-tape ply bundles, each of said uni-tape ply bundles includes uni-tape plies and a first spacer ply;
- a multiple of spacers, 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 at said respective level;
- a multiple of interstitial ply layers, each one of said multiple of interstitial ply layers being adjacent to a respective level of said multiple of uni-tape ply bundles and said multiple of spacers within said respective level;
- and
- wherein said first rib and said second rib of said rib pattern define a space at each of said respective levels, said space extending at least partially between said respective levels, said space being free of said multiple of uni-tape ply bundles and said multiple of spacers, and said interstitial ply at least partially disposed within said space.
