Abstract: Flax noil fibers reinforced polylactide composites were prepared by means of flax noil fibers and polylactide fibers , non 2 woven method and moulding pressing technology. The effect s of carding times , volume
f raction of flax fibers and moulding temperature on tensile st rength of the composites were discussed respectively , and the tensile f racture surfaces and the adhesion were examined by scanning elect ron microscopy. The result s reveal that the tensile st rength reaches a peak at 190 ℃and volume f raction of 39. 6 %. The st rength increases first with the carding times and then decreases , which reaches the highest point af ter two carding times. The f racture surface reveals that the breakage property of the composite is brit tle , and the adhesion between flax fibers and the mat rix needs to be improved.
