Effect of aluminum hydroxide/epoxy coating on the flammability indexes of cotton/epoxy laminated composites

In recent years, natural fiber laminated composites are extensively applied to fabricate various structures. Despite the numerus advantages of natural fiber laminated composites, flammability is one of the limitations to use them in different applications. Hence, this paper focused on the evaluation of the effect of additives on the flammability index of natural fiber laminated composites. An epoxy-based coating reinforced by different loadings of aluminum hydroxide was used on the surface of cotton/epoxy laminates. The fire behavior of the epoxy-based coating was characterized by a cone calorimeter device. The results manifested that by increasing the amount of aluminum hydroxide, the thermal properties of laminated composites will be enhanced.
