摘要：	The aircraft tire is a complex composite structure containing reinforcing nylon cords in a rubber matrix. It experiences a very complex loading during usage. There are inflation induced stresses as well as the centrifugal and flexural stresses induced by rolling. The material is exposed to cyclic thermal loading from heat generated by distortion and braking. All of these influence the useful life and performance of the tire. The tire designer needs to have an understanding of the constitutive properties of the aircraft tire and the influence of environment and loading on those properties. In this study, unused aircraft tires were cut open and specimens extracted to test for constitutive properties and a very important mechanical property called peel strength. The procedure for extracting the coupons, the fixturing and the simulated loading conditions used in the laboratory are discussed. Three kinds of peel test configurations were compared in a baseline study. The best configuration was then used to test conditioned coupons. The results and statistical analysis of these tests are presented.
