| 摘要: |
The epoxy resin matrix of carbon fiber (CF)-reinforced
epoxy composites was modified with novolac resin
(NR) to improve the matrix-dominated mechanical
properties of composites. Flexural strength, interlaminar
shear strength (ILSS), and impact strength were
measured with unfilled, 7 wt% NR, 13 wt% NR, and 18
wt% NR filled to epoxy to identify the effect of adding
NR on the mechanical properties of composites. The
results showed that both interfacial and impact properties
of composites were improved except for flexural
property. The largest improvement in ILSS and impact
strength were obtained with 13 wt% loading of NR.
ILSS and impact strength were improved by 7.3% and
38.6%, respectively, compared with the composite
without NR. The fracture and surface morphologies of
the composite specimens were characterized by scanning
electron microscopy. Intimate bonding of the
fibers and the matrix was evident with the content
of 7–13 wt% NR range. Decrease of crosslinking
density and formation of NR transition layer were
deduced with adding NR. |
