Referring to FIG. 10, a preform structure, such as preform structure 1000, includes a plurality of reinforcement wraps and a plurality of preform inserts. Reinforcement wraps of the preform structure include a first reinforcement wrap 1002, a second reinforcement wrap 1004, a third reinforcement wrap 1006, a fourth reinforcement wrap 1008 and a fifth reinforcement wrap 1010. Preform inserts include a first preform insert 1012, a second preform insert 1014 and a third preform insert 1016. The reinforcement wraps 1002, 1004, 1006, 1008 and 1010 may be provided as exemplarily described above with respect to one or more of the reinforcement wraps 604, 606, 608 and 704. The preform inserts 1012, 1014 and 1016 may be provided as exemplarily described above with respect to the reinforcement insert 702.

As exemplarily illustrated, the first and second reinforcement wraps 1002 and 1004 are positioned closely adjacent to one another, but end portions of the first and second reinforcement wraps 1002 and 1004 are separated from one another such that an edge 1002a of the first reinforcement wrap 1002 is spaced apart from an edge 1004a of the second reinforcement wrap 1004. The first preform insert 1014 may be inserted between the first and second reinforcement wraps 1002 and 1004 at the edges 1002a and 1004a thereof. Similarly, the third and fourth reinforcement wraps 1006 and 1008 are positioned closely adjacent to one another, but end portions of the third and fourth reinforcement wraps 1006 and 1008 are separated from one another such that an edge 1006a of the third reinforcement wrap 1006 is spaced apart from an edge 1008a of the fourth reinforcement wrap 1008. The second preform insert 1016 may be inserted between the third and fourth reinforcement wraps 1006 and 1008 at the edges 1006a and 1008a thereof.

Taken together, the first and second reinforcement wraps 1002 and 1004 form a first preliminary preform structure 1018. Similarly, the third and fourth reinforcement wraps 1006 and 1008 form a second preliminary preform structure 1020. The second reinforcement wrap 1004 of the first preliminary preform structure 1018 is positioned closely adjacent to the fourth reinforcement wrap 1008 of the second preliminary preform structure 1020 at edges 1004a and 1008a thereof, but the second and fourth reinforcement wraps 1004 and 1008 diverge to extend axially in opposite directions. The third preform insert 1012 may be inserted between the first and second preliminary preform structures 1018 and 1020 at the location where the second and fourth reinforcement wraps 1004 and 1008 diverge. Finally, the fifth reinforcement wrap 1010 may be positioned closely adjacent to the second and fourth reinforcement wraps 1004 and 1008 such that the third preform insert 1012 is trapped in the radial and axial directions between the second, fourth and fifth reinforcement wraps 1004, 1008 and 1010.

It should be appreciated that the reinforcement wraps 1002, 1004, 1006, 1008 and 1010, and the preform inserts 1012, 1014 and 1016 may be coupled together in any suitable manner (e.g., by stitching, or the like), and in any sequence suitable for forming the preform structure 1000 exemplarily described above. Constructed as described above, exterior surfaces of the preform structure 1000 include a preform termination surface 1022, a radially-facing inner surface 1020, a radially-facing outer surface 1026, a second axially-facing surface 1028, a transition surface 1030, and an inclined surface 1032. Upon providing the ceramic matrix material to, for example, infiltrate the preform structure 1000, the attachment termination surface 126, radially-facing inner surface 108, radially-facing outer surface 110, second axially-facing surface 114, transition surface 122 and mating surface 124 can be formed to generally correspond to the preform termination surface 1022, a radially-facing inner surface 1020, a radially-facing outer surface 1026, a second axially-facing surface 1028, a transition surface 1030, and an inclined surface 1032, respectively.

Referring collectively to FIGS. 11 and 12, a blade track assembly 1100 includes a hanger 1102 coupled to a blade track, such as the blade track illustrated and described above with regard to FIGS. 1 and 3. It will nevertheless be appreciated that the blade track assembly may include any blade track having an attachment portion according to any embodiment, or combination thereof, exemplarily described above.
