Moldflow是一款模拟仿真分析软件,能够优化塑料零件、注塑模具和成型过程,为实际设计提供指导.本文利用Moldflow软件对键盘外壳进行纤维取向的分析.分别分析材料、注塑工艺、纤维含量对纤维取向的影响；以及纤维含量对注塑成型过程的影响.
分别选取填充20%GF的ABS、PPV、PP材料,在相同的工艺条件下,20%GF在三种材料中,平均纤维取向以及纤维取向张量受材料分子结构的影响均有所不同.
选取PC+ABS+20%GF材料,分别改变模具温度、熔体温度,平均纤维取向均有所变化,纤维泊松比为0.4219,定值不变,而纤维取向张量只受熔体温度影响.
选取聚丙烯（PP）材料分别加入不同比例的玻璃纤维（GF）,在相同工艺条件下,随着纤维含量的增加,平均纤维取向呈先减小后增大的趋势变化；制品变形量呈减小趋势,但当纤维含量为35%时,变形量急剧增大,之后又呈减小趋势.

　　Moldflow, a simulant and emulational analysis software, can optimize plastic hardware, injection moulds and molding processes and provide a practical design with direction. By means of the Moldflow, this paper makes some analysis on the fiber orientation to the keyboard case and analyzes the influence on the fiber orientation by the material, the molding technics and the fiber content respectively and the influence on the process of injection molding by the fiber content,
　　分别选取填充20%GF的ABS、PPV、PP材料,在相同的工艺条件下,20%GF在三种材料中,平均纤维取向以及纤维取向张量受材料分子结构的影响均有所不同.

　　Respectively select the filler materials ABS, PPV and PP of GF and on the same technics term, the tensors of 20% of GF’s average fiber orientations of the three materials are different from each other because of the influence from their respective molecular structures.

　　选取PC+ABS+20%GF材料,分别改变模具温度、熔体温度,平均纤维取向均有所变化,纤维泊松比为0.4219,定值不变,而纤维取向张量只受熔体温度影响.

　　Select the material PC+ABS+20% of GF and alter the temperatures of the mold and the fusant respectively, and the average fiber orientation has somewhat change: the Poisson's ratio of fiber is 0.4219 and the Fixed value is the same while the tensor of the fiber orientation is only influenced by the temperature of the fusant.

　　选取聚丙烯（PP）材料分别加入不同比例的玻璃纤维（GF）,在相同工艺条件下,随着纤维含量的增加,平均纤维取向呈先减小后增大的趋势变化；制品变形量呈减小趋势,但当纤维含量为35%时,变形量急剧增大,之后又呈减小趋势.

　　Select polypropylene (PP) and add to different proportional fiber-glass, and, on the same technics terms, the average fiber orientation shows a trend to change to decreasing first and increasing later as the fiber content is increasing; although the finished product shows a decrescent trend, the deflection increases rapidly when the fiber orientation is 35% and then it shows a decrescent trend once more.
