摘要:
以碳纤维/丁腈橡胶基密封复合材料为对象,采用ABAQUS有限元分析软件,建立含有界面相的三维有限元模型,研究了橡胶基复合材料热残余应力的分布规律。探讨了制备温度、界面相厚度、界面相模量描述方法、纤维体积分数、纤维直径对热残余应力的影响。结果表明:制备温度的变化对纤维和界面相的热残余应力影响较大; 界面相厚度对纤维的残余应力的影响比其对自身的影响大; 梯度界面有利于降低复合材料的热残余应力; 适当提高纤维体积分数和增加纤维直径都有助于改善复合材料热残余应力的分布。
Abstract:
By ABAQUS software,a three-dimensional finite element model containing the interphase was established for the analysis of thermal residual stress distribution in nitrile rubber matrix sealing composite reinforced by carbon fiber.The effects of fabrication temperature,interphase thickness,interphase modulus’ describing methods,fiber volume fraction and fiber diameter on the thermal residual stresses were investigated.Results showed that the changes of the fabrication temperature had significant effect on the stresses in fiber and interphase; the thickness variation of interphase had more impact on the stresses in the fiber than that in interphase itself; gradient interface could reduce the thermal residual stress of the composites; an appropriate increase in fiber volume fraction and fiber diameter was conducive to improving the distribution of the thermal residual stress in the composites.
