摘　　要：用自制热致液晶性纤维素芳族酯（ＡＥＣ）与聚碳酸酯（ＰＣ）进行了注塑原位复合的研究。结果表明：复合物的拉伸模量．弯曲模量及强度均随ＡＥＣ用量增加而增加，拉伸强度在ＡＥＣ含量为１０％时达到最大值；复合物力学性能的变化与其中ＡＥＣ液晶微纤的数量和形态密切相关。injection mold in situ copmosite of thermotrpic liquid crytalline aromatic esterof cellulose (AEC) with polycarbonate (PC) were studied in this paper. The tensile modulasbend modulas and bend strength of PC/AEC injection mold parts inhanced with increasingAEC content and the tensile strength reached the maximum value when AEC content is10 %. The mechanical properties of the in situ composite were determined by the amound andmorphology of AEC microfibrils.
