Study of the effect of the weather factors on the mechanical properties of the composite material of foam polystyrene and natural wool

Abstract

This study investigates the utilization of natural wool as a natural additive to foam styrene, aiming to assess its influence on the mechanical properties of the resulting composite material. Previous research on wool processing was utilized before adding it, our research concluded that 15% wool treaded wool yielded the best rate in terms of water absorption and combustion time. However, it was observed that compression resistance increased with higher additive ratios.  The effect of weather factors on the resulting material was investigated by subjecting it to external atmospheric conditions for four months. Repeated tests were conducted to distinguish any variations in the properties of the composite material before and after exposure to these weather factors
