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. 1- M6DAU Vat lieu polyrne eompozit co nhieu tinh chat iru viet nhu kh6i luong rieng nho, do ben co IS' cao, chiu mai mon tot, nang suat gia c6ng Ian nen ngay cang diroc irng dung rang rai de thay the mot phan de vat lieu truyen th6ng.
