microscope and
infrared spectra. The results shown that the change in chemical compositions
morphology of fiber surface was increased ability of adhesion with PP resin
matrix.
2. The piece of bamboo mat was fabricated from treated bamboo fibers by
random depositing in the water.
3. The cummulative probability of the tensile strength of untreated and
alkali-treated bamboo fibers was proved that both the tensile strength of treated
fibers and the young’s modulus of treated fibers decreased because fracture
strain of treated fibers increased.
4. The contact angles for the surface treated bamboo fibers proved that the
alkaline treatment does leading an crease of hydrophobic of bamboo fibers, the
contact angle increase from 65,030 to 73,230 in the water.

5. When combine MA with PP resin at appropriate content, the hydrophobic
of PP was decreased, the contact angle decrease from 93,360 to 91,330 in the
water.
