A laminate preform for a ceramic matrix composite (CMC) component, the laminate preform comprising at least one ply including a prepreg formed with an impregnated set of tows, at least one tow in the impregnated set of tows twisted through at least one turn/meter, and having at least one bridging fiber extending between adjacent plies.
2. The laminate preform of claim 1 , wherein the at least one ply comprises multiple plies stacked to define the laminate preform.
3. The laminate preform of claim 2 , wherein the at least one tow in the impregnated set of tows is twisted between 1 turn/meter and up to and including 20 turns/meter.
4. The laminate preform of claim 3 , wherein the at least one tow in the impregnated set of tows is twisted between 5 turns/meter and up to and including 10 turns/meter.
5. The laminate preform of claim 2 , wherein at least one tow in every other ply in the multiple plies includes a pattern with one of a left handed twisted tow and a right handed twisted tow.
6. The laminate preform of claim 2 , wherein the at least one tow is every tow in the impregnated set of tows.
7. The laminate perform of claim 1 , wherein the impregnated set of tows at least one twisted tow.
8. The laminate preform of claim 7 , wherein each set of tows include at least one twisted tow to form a plurality of prepregs.
9. The laminate perform of claim 8 , further comprising multiple plies formed by the plurality of prepregs, the multiple plies being stacked to form the laminate preform.
10. The laminate preform of claim 9 , wherein each ply comprises a row of twisted tows, and the row of twisted tows is formed with a pattern consisting of at least one of left-hand twisted tows, and right-hand twisted tows.
11. The laminate preform of claim 10 , wherein the pattern includes left-hand twisted tows and right-hand twisted tows.
12. The laminate preform of claim 10 , wherein multiple rows define a set of rows and every other set of rows includes the pattern.
13. The laminate preform of claim 1 , wherein the impregnated set of tows are wrapped around a drum.
14. The laminate preform of claim 13 , wherein the impregnated set of tows are formed by a plurality of fibers that are bundled together.
15. The laminate preform of claim 14 , further comprising a coating deposited on the plurality of fibers via a chemical vapor deposition (CVD) process to form a coated plurality of fibers prior to bundling the plurality of fibers.
16. The laminate preform of claim 1 , wherein the impregnated set of tows include a binder including a ceramic matrix precursor.
17. The laminate preform of claim 16 , wherein the impregnated set of tows at least one twisted tow, and the at least one twisted tow is impregnated with a binder being a matrix slurry.
18. The laminate preform of claim 1 , wherein the impregnated set of tows are formed by a set of tows that are woven or braided prior to impregnating the impregnated set of tows.
19. The laminate preform of claim 1 , wherein the impregnated set of tows are formed by a plurality of fibers that are bundled together, and wherein the impregnated set of tows are formed by a plurality of fibers that are bundled together further comprising depositing a coating on the plurality of fibers via a chemical vapor deposition (CVD) process to form a coated plurality of fibers prior to bundling the plurality of fibers.
20. The laminate preform of claim 1 , wherein the laminate perform is used within a turbine engine.
