摘要

建立了碳纤维复合材料(CFRP)雷电冲击特性的实验平台

通过实验验证和对CFRP等效电路模型的分析

提出了采用两电极测试系统

通过检测流经CFRP层合板的脉冲电流和其两端的动态电压

研究了CFRP动态特性的测试方法

分析了在雷电流A分量作用下CFRP的动态特性。实验结果表明:在峰值时间为30.2 μs、半峰值时间为72.2 μs的非破坏雷电流A分量冲击作用下

碳纤维复合材料具有较强的导通能力

并且随着脉冲电流强度从5 A增加至100 A

其电阻由20 Ω减小至2 Ω左右

即具有显著的非线性; CFRP试品两端的电压先于电流达到峰值

材料整体显示出一定的电感效应。利用建立的CFRP层合板的等效电路模型

对CFRP在雷电流冲击下表现出的动态电阻非线性、电感特性、高导电微碳纳米管(MCNT)夹层对材料动态伏安特性的影响等现象进行了合理的解释。研究结果为CFRP的电气特性、树脂热降解、温度场分布以及热失重等研究提供了必要的理论支撑

同时为CFRP在航空航天领域的广泛应用奠定了坚实的基础。

Abstract

An experiment platform is established to measure lightning impulse characteristics of carbon fiber reinforced polymer(CFRP)

on which the experimental circuit and structures of CFRP are developed to propose a suitable two-electrode testing method. The dynamic characteristics of CFRP under non-destructive lightning current A wave(T

=30.2 μs

=72.2 μs)are investigated. The experimental results show that the carbon fiber composite material has a strong conduction capability under lightning impulse

and its impact resistance exhibits significantly nonlinearity

and a close relationship between surface coating mat

erials and internal layer-structures is revealed. Considering the internal ply structure

surface material and conductivity of carbon fibers

micro carbon nanotubes layers and polymer

the lightning conducting model of CFRP is established. The inductance characteristics

nonlinear dynamic resistance characteristics as well as the linear trend in dynamic V-I characteristics can be well explained.
