Systematic Techniques of Hose Failure Mode Analysis

Systematic techniques to analyze industrial and automotive hose failures are presented. End use requirements for textile reinforcement cords versus hose specifications and end use operating environments are assessed. Hose design criteria are examined from a reverse engineering manner. The Facts Mapping technique is offered as a vehicle to manage the data generated in the failure analysis. A definition of a hose failure is offered. Proper selections of the hose inner-liner and cover materials and the reinforcement cord are emphasized.
