Physical testing of aviation tire inner tubes

Aviation tire inner tube physical test can measure the physical properties of various types of aviation tire inner tubes such as tensile strength, aging, tearing, hardness, brittleness temperature, and adhesion between valves and rubber pads.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various tires and provides professional durability testing services for aviation tires.

Aircraft tires are classified in many ways, including: type, ply level, with or without tubes, and bias or radial tires. There are also ways to identify tires based on their size.

1. Tensile property test The tensile property test of the inner tube rubber includes the measurement of the tensile strength of the tire body rubber, 500% elongation stress, elongation at break, permanent deformation at break and the tensile strength of the joint rubber.
2. Aging performance test
3. Tear strength test
4. Hardness measurement
5. Brittle temperature test
6. Adhesion strength test between valve and rubber pad
