METHODS AND PRECURSORS FOR MANUFACTURING A PERFORATED COMPOSITE PART

Precursors and methods for manufacturing perforated composite parts are disclosed. An exemplary precursor (19) comprises structural fibres (24,28) embedded in a cured matrix material (24,26) and interposed between two removable plies (20). The precursor may also comprise a sacrificial fibre (28) ext...

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