Most fuel cells that are widely used in commercial and military aircraft as a fuel storage are made of rubber compound materials. Fuel cells are critical part of the aircraft structure.
This theory has confirmed the most ideal splice condition of rubber compound materials, hoping it will solve repairing difficulties due to functional degradation of fuel cell rubber materials after long-term use.
Five samples per part are used to measure the maximum tension load in order to find splice traits of rubber compound materials per surface roughness and testing temperature which, then, are compared in correlation.
As a result, regarding the testing temperature, those made in high temperature demonstrates higher maximum disconnection load than those made in room temperature; regarding the surface roughness, those greater than 600 in both room and high temperature demonstrate high disconnection load. Moreover, as observed in disconnected surfaces per each testing temperature, those made in high temperature show smaller and higher number of dimples than those made in room temperature, which proves the surface made in high temperature with more dimples has greater splice capacity than the surface made in room temperature.
