Experimental Study on the Thermodynamic Properties of Carbon Fiber Hollow Fabric Composites

Abstract

This paper presents a study on the thermodynamic properties of 15 mm resin-based carbon fiber hollow fabric composite, which was prepared by vacuum drainage molding process. Firstly, the experimental tests were carried out to obtain the mechanical property and thermal conductivity of the carbon fiber hollow composite. Then the comparison between the carbon fiber hollow fabric composite and the traditional aluminum honeycomb thermal conductive composite in heat conduction mechanism and heat conduction material structure. Finally, the application of carbon fiber hollow composite in the field of heat conduction was introduced with a discussion on the its future development in the aerospace field. The results show that the three-dimensional carbon fiber hollow composite is more superior than the traditional aluminum honeycomb composite in comprehensive mechanical properties, and it is almost the same as traditional aluminum honeycomb composite in thermal conductivity. Therefore, it can be concluded that the three-dimensional carbon fiber hollow composite could be an ideal structural material to replace the traditional honeycomb and foam sandwich composites used in the field of aerospace technology.
