| 摘 要： | 研究了硼钛复合纤维在拉伸过程中的行为，结果表明：复合纤维的变形是由纤维的弹性应变与基体的弹塑性应变复合迭加而成，并且在纤维与基体结合十分牢固，基体组元体积分数又较少的情况下，复合纤维表现为高强度，高弹性模量及低塑性，将试验结果同理论计算模型进行了比较，所得结果基本一致。

| Abstract: | Characterization of Bw / Ti composite fiber stress-strain response was explored.Both of experimental and composite consists of elastic deformation of fiber and elastic-plastic deformation of matrix. In addition ,under the condition of firmly coherent interface between fiber and matrix as well as less than 50% volume fraction of matrix compc-nent,the composite fiber performs a high strength,high modulus and low plasticity behavior which means ensurement of excellant properties for fiber and limitation of plastic potentiality for matrix. Finally ,comparison between experimental and theoretical results was made and the agreement of both was satisfactory. |
