Abstract

The invention discloses a dynamic fatigue evolution test method for rubber and fiber cord thread bonding, by means of connecting a fixture with an MTS elastomer test system, the method realizes simulation of continuous evolution process of bonding failure of rubber and a fiber cord thread under various conditions of use in multiple modes such as constant stress, constant strain as well as alternating load and alternating frequency. The beneficial effects of the method are that: the method is simple to operate, the data is reliable, the reproducibility is high, the test process has time continuity, so the method can better simulate the evolution process of bonding fatigue rupture of multiple kinds of rubber and various fiber cord thread composite materials under the condition of real stress, and has important guiding significance for predicting the service life of rubber products,thereby having a broad application prospect.

Description

technical field

[0001] The invention relates to the technical field of rubber and fiber cord composite materials, in particular to a dynamic fatigue evolution test method for rubber and fiber cord bonding. Background technique

[0002] With the popularization of automobiles and the improvement of modernization level, people's requirements for tire performance are becoming more and more stringent. Among all performances, the durability and service life of tires are of great concern to the tire industry and consumers. In tires, fiber cords are widely used as a skeleton material in carcass structures. As two materials with completely different properties, their adhesion is directly related to the safety of the tire. Therefore, in order to ensure that high-quality tires are put into use, the tire factory must test the bonding of rubber and fiber cords.

[0003] At present, the most simple and commonly used method to measure the adhesion between rubber and fiber cord is the ...
