摘要
综合论述了连续纤维增强钛基复合材料热残余应力的分析方法如:X 射线衍射和中子衍射方法、剥层法、基片弯曲法以及选择基体腐蚀法等,以及热残余应力对复合材料力学性能的影响。就热残余应力的影响因素总结了人们在降低复合材料热残余应力方面所作的各种努力,在此基础上指出了当前研究存在的缺陷和今后的发展方向。
This paper reviews the analytical measurements of thermal residual stresses (TRS) for continuous fiber reinforced titanium matrix composites, such as X-ray and neutron diffraction, layer removal method, slitting method, selectively matrix corrosive method and so on, and the effect of TRS on mechanical properties of the composite, and discusses the different kinds of methods for reducing the thermal residual stresses. Finally, present investigative limitation and areas for further research are outlined.
