摘要/Abstract

摘要： 目的： 研究玻璃纤维体积含量对纤维增强型复合体抗弯曲性能的影响。方法： 通过改变预浸树脂基体中纤维粗纱股数，改变光固化纤维增强复合体中玻璃纤维的体积含量，利用三点弯曲实验检测不同纤维体积含量时纤维增强型复合体的弯曲性能，最终确定最佳纤维体积含量比。采用SPSS 20.0软件包对数据进行统计学分析。结果： 纤维体积含量为60.4%时，复合材料的三点弯曲强度和弹性模量达到最大。结论： 复合体的弯曲性能随玻璃纤维含量的增加而提高，达到峰值后，再增加纤维含量，弯曲性能反而下降。

Abstract: PURPOSE: To investigate the effect of glass fiber volume content on the flexural property of fiber-reinforced composite. METHODS： The specimens of composite were fabricated with 4 different glass fiber volume contents by changing roving winded number of strands dipped in resin matrix, and the mechanical properties were tested by 3-point flexural test in order to determine the optimal fiber volume content. The data was analyzed statistically with SPSS20.0 software package. RESULTS: Self-made fiber-reinforced composites with the glass fiber volume content percentage of 60.4% achieved the maximal flexural strength and the maximal elastic modulus. CONCLUSIONS: As the glass fiber content in matrix of composite material is increased in certain range, the flexural strength and the elastic modulus can be improved，then reaches the peak. However, the flexural property decreases rather than rises when the fiber content is more than 60.4%.
