The characterization of glass fibre reinforced unsaturated polyester filled with P84 Polyimide / multi-wall carbon nanotubes (mwcnt) hybrid composites / Nik Noor Idayu Nik Ibrahim

This study was carried out with an aim to improve the strength and
thermal stability of the glass fibre reinforced unsaturated polyester
composites by incorporating the P84 Polyimide powder and Multi-wall
Carbon Nanotubes (MWCNT) as filler. Research methodology for this
study was divided into four main stages. First stage is the preliminary
study on the effect of the masterbatch technique on the basic properties
of unsaturated polyester. Masterbatch technique is the mixing of
powder P84 Polyimide with liquid MEKP prior to be incorporated into
the polyester resin, where a mixture that contain both filler and curing
agent was produced. This mixture were prepared in bulk, stored in a
closed container and only taken out when needed. The results showed
that the masterbatch technique does not affect the gel time but does
increased the Tg. The second stage was the preparation of the matrixfilled
system as a function of different preparation techniques where
two matrix systems were studied. First was the unsaturated polyester
filled with masterbatch P84 Polyimide system and the second was the
unsaturated polyester filled with P84 Polyimide system. The difference
between the systems was the preparation technique. The first system was
prepared by incorporating both filler and curing agent (masterbatch P84
Polyimide) simultaneously into the polyester resin...
