Abstract
The effects of the number of layers, the arrangement of carbon fiber (CF) tow and the epoxy resin (ER) matrix on the fire performance of carbon fiber/epoxy composites (CFEC) were studied by a variety of experimental methods. The results show that the number of layers of CF tow has influence on the combustion characteristics and fire propagation of the composites. The arrangement of CF tow has influence on flame propagation rate and high temperature mechanicalproperties. The mechanism of the influence of the number of layers of CF tow on the composite is mainly due to the different thermal capacity of ER matrix. The effect of the arrangement of CF tow on the fire performance of the composite is mainly due to the inhibition and obstruction of the tow on the combustion of ER matrix. The influence on the high temperature mechanicalproperties is mainly due to the different arrangement direction of CF tow. The fitting equation of the mechanicalproperties of the samples was obtained. This equation could be used to predict the samples’ tensile strength from 25°C to 150°C by comparing with the experimental results. Taking the carbon fiber woven cloth (C) applied in the fuselage material as an example, combining the influencing factors of various parameters in the fire field, some suggestions are put forward combined with the research conclusion.
