Abstract

A method of fabricating a composite part comprising fibre reinforced material in a mould (10a, 10b, 10c), the method comprising the steps of: depositing fibre material on a mould surface; covering the fibre material with a vacuum film to create a mould cavity that contains the fibre material and is substantially sealed; evacuating air from the mould cavity; detecting if there is an air leak into the mould cavity with an acoustic camera unit (31) during and/or after the step of evacuating air from the mould cavity.
