To study of Life Time Prediction of Nylon Rope using Aging Property, Thermal Behavior and Physical Properties’

Abstract

This work aim is To study of Life Time Prediction of Nylon Rope using Aging Property, Thermal Behavior and Physical Properties In This work taking nylon rope experimental test were performed in ASTM D3045 standard for breaking strength. firstly in this project the nylon rope samples are keep in heat aging oven at 70 0 c temperature for 0,1,3,6,12,23 weeks. after the completion, test the material in universal testing machine for breaking strength In the present investigation the Breaking Strength, was determined as a function of time with the constant exposure to the plastic product at 70°C for 23 week. The sample was initially determined the properties and considered as 0 days sample or base property of the material. The sample was drawn in the interval of B-1,3,6,12,23 Weeks. The regression analysis was conducted on the test data and the prediction of the life span of the products was made as per ASTM. Use the regression equation to determine the exposure time necessary to produce a predetermined level of property change. An acceptable regression equation must have an r 2 of at least 80
