摘要

摘要: 采用变温拉曼光谱mapping扫描技术研究了在升温过程中炭纤维（CF）增强聚酰亚胺（PI）/碳纳米管（CNTs）复合材料的微观力学行为。其中CF为增强材料，CNTs作为应力传感媒介，两者都具有拉曼温度敏感性。获得了各温度条件下（25~300℃） CF/CNTs-PI复合材料界面微区的应力分布变化图。在200℃以下，CF/CNT-PI薄膜中纤维与界面区域压应力分别在122 MPa与74 MPa附近，应力分布从纤维到基体逐渐减小。200℃为残余应力消除温度，CF/CNT-PI薄膜内部应力接近于0 MPa。然而，当加热超过200℃时，薄膜主要承受拉应力，且主要分布在CF上。此外，发现CF与基体之间的应力传递小于100%。这些结果均证明复合材料中的应力随温度而变化，而CF具有优异的增强作用。

Abstract: Temperature-variable Raman spectroscopy equipped with mapping function was used to investigate the micro-mechanical properties of a carbon fiber (CF) reinforced polyimide(PI)composite film using carbon nanotubes (3 wt%) dispersed in PI as the stress sensor. The stress distributions on CFs and the interface region during heating from 25 to 300℃ were mapped based on the stress sensitive Raman G' band (around 2679 cm^-1) shifts of CNTs. Results indicate that thermal motion of PI chain affect the mechanical properties when the CF/CNT-PI film was heated up to 300℃. Both CFs and interface region were compressively stressed below 200℃. The compressive stress decreased with temperature and was approximately eliminated at around 200℃. Tensile stress developed above 200℃ and increased with temperature, which was distributed mainly on CFs. Furthermore, the stress transfer between CFs and matrix was less than 100% due to the thermal stress hysteresis in the PI matrix.
