雷击对碳纤维增强型航空复合材料损伤的影响
Effects of Lightning Strike on Damage of Aeronautical Carbon Fiber Reinforced Plastic
摘要
Abstract
T he thermal‐electric finite element simulation model of carbon fiber reinforced plastic (CFRP) damage caused by lightning strike was established .The superimposed temperature was trea‐ted as the internal injury .The accuracy and effectiveness of coupled thermal‐electric simulation meth‐od were verified by comparing with the experimental results .The regression analysis was taken into consideration to give a quantitative analysis of lightning parameters and CFRP lightning damage ,and the relevant curves were drawn .The results show that action integral is a key factor in determining the injury status of CFRP laminates .Fiber damage area and delamination area have a linear relation‐ship with the action integral .And resin damage area and damage thickness have a logarithmic relation with the action integral .关键词
