摘要/Abstract

摘要： 以碳纤维/环氧树脂层压板为研究对象，利用ABAQUS有限元分析软件对高温环境下碳纤维/环氧树脂层压板热响应过程进行数值模拟，结合试验分析不同铺层厚度材料的热响应行为规律，验证了模拟的可行性。研究发现，随着厚度增加，材料达到稳态温度的时间延后，稳态温度降低，材料内部随着距受热面深度的增加，升温速率呈下降趋势，且随着深度的增大，下降趋势减缓；热流方向沿平行于碳纤维层分布时稳态温度和稳态导热系数均较垂直方向大，碳纤维沿平行于热流传递方向分布有利于传热。

Abstract: This paper takes carbon fibre/epoxy laminate as the research object, and uses ABAQUS finite element analysis software to numerically simulate the thermal response process of carbon fibre/epoxy laminate under high temperature environment, combined with the experimental analysis of the thermal response behaviour of the material with different layer thickness, to verify the feasibility of the simulation. It is found that as the thickness increases, the time to reach the steady-state temperature is delayed and the steady-state temperature decreases, and the temperature rise rate inside the material decreases with the increase of depth from the heated surface, and the decreasing trend decreases with the increase of depth; the steady-state temperature and the steady-state thermal conductivity are greater when the heat flow direction is distributed along parallel to the carbon fibre layer than along vertical, and the distribution of carbon fibre along parallel to the heat flow transfer direction is more beneficial to heat transfer.

Key words: carbon fiber/epoxy laminate, thermal response behavior, high temperature environment, steady state temperature, steady-state thermal conductivity
