Abstract

In this study, “correlation analysis” was used to calculate the physical and mechanical property index data of the prepared composite materials. After preparing such composites with neoprene/chromium leather fillings and adding 15% of pineapple leaf fibre, we examined the properties of RL/NA/PLF tensile strength and elongation at break, tensile strength and collapse strength, elongation at break and collapse height, permeability and 15min water absorption, permeability and 24h water absorption, 15min and 24h water absorption, 24h water absorption and surface wetting, tensile strength and 15min water absorption, tensile strength and 24h water absorption, tensile strength and 24h water absorption, resistance. The results showed that the correlations between tensile strength and surface wettability, collapse strength and permeability, collapse strength and 15min water absorption, collapse strength and surface wettability are opposite to the corresponding indexes of RL/NA. This result is due to the pineapple leaf fibre itself having high strength, low elongation, good water absorption and good air permeability characteristics, which give these results when coupled with the interaction with neoprene adhesive and chrome tanned leather collagen fibre.
