分别以五种聚烯烃树脂为基体，采用自行设计的浸渍模具制备了连续玻璃纤维增强聚烯烃预浸带，并采用热模压机将预浸带压制成相应的板材。研究了五种基体树脂、纤维含量、纤维分布对复合材料力学性能的影响。结果表明，加入玻纤后复合材料的拉伸强度、弯曲强度大幅度提高，纤维分布对材料的弯曲性能影响较大；纤维含量0～70％范围内，随纤维用量的增加，复合材料的力学性能提高；在70％～75％范围内，复合材料的力学性能随纤维含量的增加而降低。动态力学分析表明，加入纤维后明显提高了复合材料的抗形变能力。

Five kinds of polyolefin resins were used as matrix ,the continuous glass fiber rein-forced polyolefin prepreg tapes were prepared by a self-designed impregnation mold and the prepreg tapes were pressed into the corresponding plate using a hot stamping press .The influ-ences of five kinds of polyolefin ,fiber content and fiber distribution on mechanical properties of composites were studied .The results show that the tensile and flexural strengths increase obvi-ously with the addition of the glass fibers ,and the influence of fiber distribution on flexural prop-erty of the composites was more obviously than that of other property .In the range of 0~70% , the mechanical properties of the composites increased with the increase of the fiber content .In the range of 70% ~75% ,the mechanical properties of the composites decreased with the increase of the fiber content .The result of dynamic mechanical behavior shows that the deformation re-sistance of the composites enhanced evidently with the increase of the glass fiber content .
