摘要

　利用电子显微及X射线衍射仪分析研究了C/Cu复合材料的界面特性及合金元素铁对C/Cu复合材料界面特性的影响.研究表明复合材料界面既无化学反应也无扩散发生

C/Cu界面是物理结合.试验表明

合金元素Fe与碳纤维发生化学反应

使C-Cu界面结合强度明显提高

因此使C/Cu复合材料的强度从592MPa提高到696MPa

横向剪切强度从64MPa提高到84MPa.化学结合型界面是提高复合材料强度的途径之一.

Abstract

The interface character of C/Cu composite and the influence of alloy element Fe are studied by means of electron microscopic analysis and X-ray diffractometer. The results show that Fe can react with carbon fiber and the interface bonding strength is improved by adding alloy element Fe. Strength of composite is increased from 592 MPa to 696 MPa as the result of iron-carbon fiber reaction. Chemical interface bonding character is one of the ways improving C/Cu composite strength.
