Abstract
Precursors and methods for manufacturing perforated composite parts are disclosed. An exemplary precursor (19) comprises structural fibers (24,28) embedded in a cured matrix material (24,26) and interposed between two removable plies (20). The precursor may also comprise a sacrificial fiber (28) extending through the removable plies (20), the matrix material (24,26) and between the structural fibers (24,28). An exemplary method comprises removing the removable plies (20) from the precursor (19) and removing the sacrificial fiber (28) from the precursor after removing the removable plies to form a through hole in the precursor (19) at a location of the sacrificial fiber (28).
