ABSTRACT: In this work, manufacturing tools for thermoplastic (TP) composites have
been developed. The chosen process involves the stacking alternately of
oriented dry fabrics and TP films and does not use semi-products in order to
reduce material costs. This study was specifically directed towards optimizing
the impregnation of continuous glass and carbon fibres reinforcing two TP
amorphous matrices, the polyphenylsulfone (PPSU) and polyetherimide (PEI), to
obtain semi-finished products employed for aeronautical structures. The
impregnation quality of inter and intra-yarns is analyzed and validated by
optical and scanning micrographic observations conducted with an optical and a
Scanning Electron Microscopies (SEM), respectively. The study showed that
besides the process parameters and porosity distribution in the core of warp
yarns, the impregnation quality depends on the surface properties of
constituents. Desizing treatment has been carried out to improve the
wettability of fibres by the TP matrices.
