Strengthening of a Fibre-Matrix Interface: A Novel Method Using Nanoparticles
The surface of carbon fabric (CF) was treated with nanoparticles (NPs) of Ytterbium fluoride (YbF3) (40‐80nm size) in various amounts (0, 0.1, 0.3 and 0.5wt%) to improve its wettability with a Polyetherimide (PEI) matrix. The effect of treatment on the fibres of the CF was also studied by adhesion t...

| Summary: | The surface of carbon fabric (CF) was treated with
nanoparticles (NPs) of Ytterbium fluoride (YbF3) (40‐80nm
size) in various amounts (0, 0.1, 0.3 and 0.5wt%) to improve
its wettability with a Polyetherimide (PEI) matrix. The
effect of treatment on the fibres of the CF was also studied
by adhesion testing and fibre tow tension testing. An
improvement in wettability with PEI and a slight reduction
in the tensile strength of the CF was observed in these tests.
Fourier transform infrared‐attenuated total reflectance
spectroscopy (FTIR‐ATR) indicated the addition of
functional groups on the fabric after treatment. Micro‐
Raman spectroscopy (MRS) showed a slight distortion in
the structure of the CF due to the treatment. Increased
roughness of the fibre surface and adhesion of NPs on the
fibre surface were observed by field emission scanning
electron microscopy (FESEM). Composites were developed
based on untreated and surface‐treated CFs by
impregnation techniques. The composites were analysed
for interlaminar shear strength (ILSS) and a maximum
improvement of 61% was observed for the 0.3%
concentration of YbF3, followed by a slight decline in ILSS,
indicating that it was the optimum dose. |
