| Résumé : |
In this paper, the pearson product moment correlation coefficient analysis method is used to show that the tensile strength of RL/CR is highly positively correlated with the elongation at break, the bursting height is highly positively correlated with the bursting strength, the tensile strength is highly positively correlated with the bursting strength, and the bursting height is negatively correlated with the elongation at break. The air permeability of RL/CR is not correlated with 15 minutes water absorption, but is negatively correlated with 24 hours water absorption and surface wettability ; The 15 minutes water absorption of RL/CR is negatively correlated with the 24 hours water absorption and the surface wettability ; The surface wettability is positively correlated with 24 hours water absorption.
The tensile strength of RL/CR is negatively correlated with air permeability, highly positively correlated with 15 minutes and 24 hours water absorption, and highly negatively correlated with surface wettability. The bursting strength of RL/CR is negatively correlated with air permeability and 15 min water absorption, and highly positively correlated with 24 hours water absorption and surface wettability. |
