Effects of humid and hot environment on fiber composites in cooling towers

ABSTRACT
Polyvinyl chloride (PVC) 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.
