TY - JOUR TI - Construction of visual 3-D fabric reinforced composite thermal performance prediction system AU - Wu Shaofei JN - Thermal Science PY - 2019 VL - 23 IS - 5 SP - 2857 EP - 2865 PT - Article AB - In view of the construction of a visualized 3-D thermal performance prediction system for fabric reinforced composites, the thermal constants analyzer was used to analyze and compare the thermal conductivity of the 3-D fabric reinforced composites by experimental methods, such as fiber volume fraction, internal braiding angle, and different yarn reduction methods and fabric structures. The factors influencing the thermal conductivity of 3-D fabric reinforced composites were studied, and the principle of thermal conductivity was analyzed. The thermal expansion coefficients of 3-D fabric reinforced composites in X- and Y-directions are one order of magnitude smaller than those in Z-directions. When aramid fabric is used as reinforcement, the composites with negative thermal expansion coefficients can be designed. The research results provide the necessary basis for the design, application and theoretical research of the 3-D fabric reinforced composites in heat conduction. Through the research of this paper, it lays a foundation for the process selection, performance design and structure optimization of this kind of material, and promotes the further application of 3-D braided composites.
