Effect of randomly distributed fibers on residual stress of SiC/GH4738 composites

Abstract In this paper, the model of SiC reinforced superalloy composite with different fiber content is established by Monte Carlo simulation method. The process of hot isostatic pressing of SiC reinforced superalloy composite is simulated, and the residual stress distribution under different fiber content is obtained. The results show that not only the fiber content has a great influence on the residual stress of hot isostatic pressing of SiC reinforced superalloy composite, but also the fiber distribution has a great influence on the residual stress. It is necessary to establish a finite element model of different fiber distribution to simulate the process of hot isostatic pressing of SiC reinforced superalloy composite.
