METHOD OF TAPE LAYING OF THERMOPLASTIC COMPOSITE MATERIALS

摘要

A method of laying up a thermoplastic composite in a mould tool (1), the method comprising: providing a mould tool having a mould surface (3), at least a portion of the mould tool comprising a porous material; applying a negative pressure to the porous material (5) so as to create a negative pressure at the mould surface; laying an initial layer (8) of thermoplastic composite material onto the mould surface, whereby the thermoplastic composite material is held against the mould surface by virtue of the negative pressure at the mould surface; and consolidating the thermoplastic composite material.
