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.
