摘要：
In this work, the mechanical properties of aged rubbers were investigated. Dynamic properties of aged rubbers with various aging times, temperatures and pre-strains were tested. Several kinds of filled rubber specimens relevant to a heavy-duty radial tyre were prepared to be prestrained in an in-house rig. The prestrained specimens were then put into an aging oven to accelerate aging. The aging times were chosen to be 24-240 h. After aging, static and dynamic mechanical tests are performed on these specimens. Some experimental results are presented and discussed to demonstrate the importance of rubber age for its time-dependent properties, especially the Payne Effect. (C) 2003 Elsevier Ltd.
