TY - JOUR TI - Effects of humid and hot environment on fiber composites in cooling towers AU - Qiu Li AU - Li Yong Gui AU - Xiong Yan Ping AU - Chen Xiao Dong JN - Thermal Science PY - 2021 VL - 25 IS - 2 SP - 1321 EP - 1328 PT - Article AB - Polyvinyl chloride materials used in cooling towers always lead to damage and low efficiency due to the hot and humid environment. This paper suggests a glass fiber reinforced material for a better performance. An optimal fractal distribution-of glass fibers in the composite matrix is experimentally obtained when the fractal dimensions are between 0.6 and 0.9.
