摘要:
提出了适用于纤维模量远大于基体模量时短纤维增强复合材料(SFRC)轴向应力分布的预测公式。建立了SFRC的轴对称单胞模型,对不同模量比下SFRC的纤维轴向应力分布进行了数值计算。通过与现有理论模型得到的应力分布对比表明,当纤维和基体弹性模量比小于37时,现有理论模型得到的纤维轴向应力和界面剪切应力均与有限元分析结果相吻合; 当模量比大于37时,现有理论模型得到的界面剪应力与有限元分析结果基本保持一致,但是纤维轴向应力与有限元分析结果相差较大。与Hsueh模型相比,提出的预测公式与实验结果更为接近。
Abstract:
A new formula was proposed for predicting stress distribution in short-fiber-reinforced composite(SFRC),which was suitable for large modulus ratio of fiber and matrix.An axisymmetric representative unit cell model of SFRC was established.The axial stress distribution along the fiber in SFRC with different modulus ratios was obtained by numerical analysis.Compared with the Hsueh’s model, the result showed that the axial stress and the interface shear stress at the fiber interface agreed well with that of the Hsueh’s model when the modulus ratio was less than 37.When the modulus ratio was larger than 37,the interface shear stress was consistent with that of the Hsueh’s model,however,the fiber axial stress was very different from the existing theory.Compared with Hsueh’s model,the results predicted by the proposed formula were in agreement with experimental ones.
