摘要
The present invention is a ceramic matrix composite turbine engine component (10), wherein the component (10) has a region of expected higher interlaminate stress (20) during normal engine operation. The component (10) includes both coated fiber tows (2) and uncoated fiber tows (6) arranged together into a preselected form, wherein the uncoated fiber tows (6) are located at predetermined regions of expected high interlaminate stress (20). The invention further includes method of manufacturing a CMC such as a composite turbine engine component (10), wherein the component (10) has a region of expected higher interlaminate stress (20) during engine operation.
