SUMMARY
Neohouzeauu dnllooa
fih(!J"s
were prepared hy mechanical method. Its composition and
morphologv
offibers
were studied. The analytical result shown that,
most
of
In-nucetlnloses
and
lignin lI't're
J"(!lI101'ed.
FTIR
spectroscop}' shows that strong
sharp
peak
in the untreated
bamboo
spectrum at
about
J73(j cin'
corresponding
to carbonyl group
(>C=O),
hut
this
peak
disappeared
in alkaline treated bamboo spectrum. Bamboo fiber reinforced polypropvleue grafted maleic

onhydride
composites IUII't' been prepared hy 50% fiber COl/tents. The mechanical properties
of
composite were also tested.
